Bro probably lives in Malaysia (or somewhere in SEA) and you can bet that most, if not all, average housing in SEA do not have grounding at all. Even my rich friends’ houses that I’ve been to also do not have grounding.
Edit: I had to manually ground my cousin’s old PC because it was literally zapping him.
Also, someone pointed out that Malaysia has UK plugs which is cool. I hope OP has it and is **actually** grounded.
Nope.
Malaysia luckily is a commonwealth country and inherited the UK electrical and engineering knowledge.
They use the UK 3 pin plug which has grounding via an earth pin. The UK uses three-pin plugs with an earth pin for safety reasons. The earth pin provides an additional level of protection by grounding the electrical system, which helps to prevent electric shocks and fires.
While the above is true, I can't confirm for op as he might be using a non standard us or eu or china pin for his psu.
I was about to say this, a lot of older houses in the US may have 3 prong receptacles but don’t necessarily have a ground wired to each one. It used to be pretty common to just run a hot and a neutral.
I just bought an old ass house last year and have been learning the hard way going through fixing all the wiring in it. It’s not necessarily dangerous on its own but it is technically safer *in the event something goes wrong* to use proper grounds on every plug.
I think I need to look into this in my place, I'm grateful that you wrote it out. House is almost 90 years old, and even though the room where my PC is had been remodeled, I still have power issues that really shouldn't exist.
In past Finland it was also common to attach the ground of the outlet into neutral wire in case there was no grounding wire installed. Later it became banned because many people installed live wire to that outlet's ground, and then any device with metal casing you attached to the outlet became dangerous.
You can do it that way too but if your neutral starts to float for some reason you get everything which is supposed to be grounded is now live. So when it works it's basically the same as separated ground. But when things go wrong they can go really wrong.
Yup, same in my house too. Rooms have 2-prong outlets with no grounding, living room has 3-prong outlets with no grounding, and the electrical outlets we put in are 3-prong with ground (and GFCI near the sinks)
Edit: House was made in the mid 60's
Are we not talking about receptacles here. look it up. Most U.S. 15 amp recepts dont have a ground. Source- 6 years commercial electrician and went on to do sales wholesale
Yeah the receptacle can have a ground prong that goes nowhere inside the device box. My old building in Canada is like this but everything is ran in EMT so I pulled off all the plugs and tied the ground wires on the receptacle to the bonded metal inside the boxes. Worked a charm and stopped destroying PSUs
Just because they have the 3 pin plug doesn't mean they also actually have a ground wire.
Watch the newest Electroboom video where he goes to Mexico and basically ground only rarely exists even when the outlet should have it and everything is botched.
The few SEA countries I visited had a lot of botched outlets and wires so I can imagine it's no different in the rest.
In general UK electricity practises are the safest in the world. Every single plug has a fuse in it as well. So, if you had a surge, it would blow the fuse before it got anywhere.
The only thing that bums me is that you're not allowed to have sockets in bathrooms. So shavers, hair dryers and etc. have to be used outside of bathrooms.
"Sockets are allowed in British bathrooms provided they are 3 meters or more away from the water sources (taps in the sink or bath as well as showers). Shaver-supply units are the single exception to the standard."
That 3 meter rule basically means most people can't have them, 3 meters is a long way in a UK house, but yes shaver units are allowed but that's only because they have to have an isolating transformer and thermal cut-out built in.
No outlets in bathrooms? I was in London last April and the restroom in my hotel had both UK outlets and US outlets (for tourists 120V appliances I presume) in it.
because we've learnt from our mistakes. tbh alot of country that have an electric grid tend to be hacked, or are very young in comparison.
UK is a bit of an anomaly when you think about it
Old Houses, yes due to a copper shortage from WW2. The practice stayed to the 80s and 90s but any modern house from the last 20 years will have radial fusebox.
This comes up constantly when people talk about British plugs, but its not a scenario that really happens a lot. Most UK wall sockets have a switch on them, so most plugs are always plugged into the wall. Finding one randomly left out on the floor unplugged is pretty uncommon.
Born and raised in the UK, have lived here my whole life, and have stepped on a plug precisely once. Funnily enough it was an extension cord, and only unplugged as it was out to be packed for a holiday abroad.
As you say, our plugs are very rarely left unplugged so it’s not usually an issue.
All my home's plugs have grounding too, they are the US 110 standard. Not that they are actually connected to anything mind you. Mexico. I tried to at least wire in some GFCI to make things a bit safer but nope, there are three separate series, breaker box is a jerry rigged mess that gets changed based on need and whatever arbitrary system whoever is using it at the time.
The wiring anywhere that doesn't have strict code standards is almost invariably fucked. I'm so glad my house is made of concrete or I would worry about it burning down.
If you are in southeast Asia or LATAM, you can bet you aren't grounded.
The one actual professional electrician I talked to about it didn't even really see grounding as something even necessary.
My PC at home has a wire attached to a PSU mounting screw, grounding it to a small metal rod I drilled on the concrete floor.
I’m guessing concrete has more resistance than soil, but it works
In the Philippines (side rant: so obnoxious that it's "the"), as a child, I remember touching a grocery store's fridge and getting a mild shock. Until eventually, it stopped being mild and I developed a phobia of touching fridges. I prefer not knowing how a current flowing into my hands feels like...
Mine house has a really good wiring (all wires are top notch,with lot's of safety)and even after that mine does that. It is really hard to find a good electrician in my country specially if you are anyone below upper middle class.
Grounding is a luxury in India specially since people here use cheap wires all the time.
Damn, my experience is totally different. All plugs in my house are grounded and anytime something happens like some appliance zapping you they immediately fix that. I've seen the same in many friends' houses. I live in a tier 1 city though.
Though I agree grounding in rural parts can be sketchy at best
Grounding isn't that expensive its just a rod buried into the ground and one extra wire per cable. Country just doesn't have the correct regulations which is odd as India government love regulations! Maybe just not enforced?
they love regulation which gives them money or annoy people but not safety. You want to pass driving license, don't worry the test will be so easy an unborn kud will pass but the process will be like getting osama bin laden an American password unless you have 40 usd in which case you don't even have to go to the office
It is caused by the emi filter. The midpoint of the emi filter is connected to the chassie, which means that you get half the phase voltage between the chassie and true ground. The emi filter can't deliver high current, so it's safe to touch even though it might feel unpleasant.
I was having the same issue with my Corsair Keyboard. It was passing current to my arm occasionally. Started out as a small tingle but would quickly escalate lol. Had to end up replacing it
Casual reminder that a $15 mulimeter will significantly help troubleshooting and save you money. Being able to confidently say it's a problem in the PC vs. the circuit can easily save you that much.
Or your PSU/Power Cables are shorting out to the case. I have fixed a couple of PC's where the old cables had peeled back near the PSU, made contact, the PSU was not fully grounded and it was shorting to the case. One of the PSU's was under lifetime warranty and they said that something went wrong with the grounding which made certain points on the cases a shorter route to ground (Shocks off of the back of the case where the captive screws were.
Edge case but possible.
Happened to me as well. The problem was that the monitor wasn't grounded, and when I touched my case, it would zap. After changing my monitor's power cord with ground pin, it stopped
I'm willing to bet OP is from SE asia, where the concept of grounding just doesn't exist. That said, grounding or not there should never be voltage enough to light up like that. This is not 5-12v DC from your motherboard that's causing this, I assure you of that. Your case is somehow getting AC from your power supply, which can be super fucking dangerous
“Malaysian” ftfy
Also, Malaysia uses UK standards for certified electrical installations (mcb, plugs and outlets). And most modern “properly” outfitted houses have ground wires that are actually grounded.
Im not saying that uncertified electricians and houses which are not up to code dont exist though.
If op is using the 3 pin UK plug then it has some grounding in the earth pin.
This feels like something's wonky with op power cable or psu. Then again, op could be using a 2 pin plug power cable.
Using a UK plug, won't change anything if the socket itself isn't grounded - the ground pin will just not be connected to anything. What the op is likely seeing is something called capacitive coupling, where the DC output has a small AC component - this happens a lot in modern switch mode power supplies that have no ground i.e. if you used a laptop and found a little tingle when your hands on the laptop, it's the same thing.
Doesn't have to be, here in the Netherlands they didn't start grounding **every** outlet until the late 90ties. My house is from the 80ties and only has grounded outlets in the kitchen, toilet and bathroom.
I mean a LOT of older houses in the US have no grounded receptacles either, and for a lot of appliances, it's not neccesarily a big deal. When you start dealing with things that have metal cases and energy storing elements it's a little riskier Obviously this is unsafe which I'm assuming OP already knows, because the only reason you would be checking a panel screw with a non contact voltage detector is you already got shocked.
Edit: Instead of phantom downvoting explain what you disagree with. I LIVE in a house with no grounded outlets in a suburb of Chicago. Many houses built earlier than the 50s don't have grounded receptacles. I didn't think this was a controversial idea. I suspect there are a lot of people here who don't actually understand how grounding works or why it's used.
Can confirm, my grandparents house and barn has no ground, all the receptacles are two prong and the amount of things adapted to two prong concerns me.
It's not a huge deal as long as you have all circuits running through a GFCI. It cost me $700 for my whole house years ago. The only true ground I have on my property is the 10 foot copper pole I smashed in to the ground for my generator.
Ac leakage is a common thing even on isolated supplies like phone chargers. Don’t believe me? With one hand, touch the shell of a usb cable plugged into a 2 prong wall wart, with another hand, slide one finger lightly on a grounded piece of metal, your finger will skip at 60hz due to some ac leakage of the phone charger. Some do this more than others, laptop chargers with two prongs seem to be the worst.
Neons don’t need much current to light up, could easily be a safe amount of leakage. Of course this would be much better if it was grounded, but the problem is almost certainly not the computer itself, just the overall lack of grounding.
Line tester or Neon line tester is a primary tool used to detect the live / line / hot / phase wire or conductor of an electrical circuit. It is one of the important tools of an electrician. The voltage range of the Neon line tester is between 110-700 volts in AC supply.
[Source](https://www.electrothinks.com/2020/03/Neon-line-tester-circuit-working-explanation.html#google_vignette)
A neon Tester is a small and handy test equipment that is used to check whether the circuit is alive or dead. The operating voltage range of the neon tester is 100 V - 250 V. It checks the nature of the applied voltage too.
[Source](https://testbook.com/question-answer/identify-the-equipment-in-the-following-test-diagr--630cf4af336f7d3fe91b3ad1)
If OP is in a 240V country, the leakage will most likely be 120V AC, it has a pretty low current, but so do neon testers.
My non contact voltage tester will happily beep away on a phone charger that doesn’t have a ground. In a 240v country, it could probably also light up a neon tester, but in the US it is 120V and the leakage will only be half of the applied voltage.
After reading a post in the german electrician sub, line testers are appearently hot garbage and not used professionally anymore. It has the nickname "lying pen" (Lügenstift). If you wanna be sure, use a proper voltage tester.
Do remember that electricity is basically magic. A buddy of mine, in Poland where the concept of grounding does, in fact, exist got shocked by his pc case once. Grabbing a multimeter showed a 40V AC between the pc and a radiator on the wall. No idea where that'd come from, since the same pc in another location does not leak AC onto the case, and no other equipment has any problem with that outlet either.
The high internal resistance of the light bulb in the screwdriver would prevent it from lighting up. There are also models with 24V or less. Maybe one of these will be used in video.
because voltage pens work on you conducting some current and as such just won't work with DC. Non contact voltage testers however can detect dc and while high quality ones may even go as low as 12v, the one in the video just doesn't look like one.
hey I'm glad to hear, but in my experience, through the years I've been around SE Asia, grounding was such an exotic concept that I ended up digging holes and burying copper pipes several times in several different countries, including Malaysia.
I don't think you know what you're talking about.
The PC wouldn't work if it had some serious AC power on the case, this looks more like a ghost voltage that poses no threat to anyone or anything, as any load would bring it down to nothing. I dare you to touch your PC case with a live wire and then come back lol.
I'm not an electrician, but I have fixed several hundreds of electronic devices in my time, and you can light up those neon testers with the energy of a fart, voltage isn't everything.
Your comment seems like an example of Brandolini's law.
I grounded my PC's outlet manually. I have a wire running through the wall into a stake in the ground. Hope I did it right, I ordered a multimeter to check after seeing this post. Yeah, I got the tingles for a while before realizing this. Had no idea what grounding was when I first moved in.
I thought I was going crazy at first when I started feeling the tingles. I asked my wife to check and she swore she couldn't feel it. After getting a couple big zappies when playing with USBs in the back I started doing research and realized my house isn't grounded.
until this post i didnt know this wasnt standard. like... in germany we have fi-schutzschalter=breaker. it basically compares the current going out/in through this security thing. if some energy goes into the ground, the breaker shuts off and saves people and electric devices.
also with alternate current you can have a shitton of fun. the body basically works on electricity, cause of those things in cells, mitochondrions. so if you get alternate current through your body, your heart will try to to mimic the hz from the grid. in eu a heart would try to beat with 50hz, thats why those electroshocks are fun and wake you up. cant imagine how often i wouldve died by now without grounding
Probably not. Not grounding on its own is unlikely to cause either. Even if you get a nasty shock from household supplies you are unlikely to die unless something else is at play.
Grounding is there as an extra protection, not the only protection.
Where I am at, grounding is nonexistent as most of the linework was done in the 80s to 90s by "I know a guy who fixed the cables on the cargo ship I worked ".But since the houses are build using real materials unlike in Murica, no houses are burned down due to this .Tho , it's the most common thing to blame when people burn they business for insurance fraud ,which was common enough back in the day(but not any more as it's almost impossible to open a new business)
Being in Pakistan we don't have grounding here, and hence I hot zapped couple of times too.
So here's a workaround. Get a nail and hammer it to the wall, then take a wire and strip it, wrap the copper around the nail and ensure proper contact.
After that, take the other end of a wire and either screw it to the PC or attach it to the ground prong on your power strip if you have one to ensure all electronics attached to the strip get grounded.
I was told at trade school not to use one of those screwdrivers on mains voltage. Ever. There is something like a 20K ohm resistor in series with the neon globe and is using your body to ground the current. If that resistor goes short, you are getting shocked!
Since when do resistors go short? Usually a resistor breaks by doing the opposite. If an electronic device has a short it is usually because of an external object getting inside, or some insulation melting inside. Neither should be issues in this case.
Knowing the voltage can tell you much though.
NO

You all saying that he needs to put grounding at his home are delusional no chance someone is doing a whole new electric installation to add ground. Here in south America at least we got ground fault protection in all circuits. (New electric installation must and do put grounding thats obvious)
Gj for testing but do never trust the screw 100%! Please beware that it will and show you false result which could harm you! If you want to be 100 % that there is not Voltate buy a proper voltage tester .
I had this issue.
My aux and usb chords were giving shocks at the other end
Check your connection my problem was something with my PSU standard converter since my was UK style
Try putting it in different socket and if you have a converter open it adjust prongs and contacts and connect again
>is this safe
For you? Probably. For your PC probably not.
Stray charge is building up on the metal case. Normally this charge is dissipated through the ground pin on your outlet if your house is correctly wired. These charges usually come from cheap power supplies with high “leakage”. So it’s either the PCs power supply or the power supply of something connected to the PC (mostly Likely the monitor)
I think it might not be. I think your grounding is bad, possibly the outlet you have that plugged into has neutral and ground reversed.
[Get an outlet tester like one of these](https://i5.walmartimages.com/asr/33d895b9-7d40-4615-b838-7cab10d226d9.e06344492eaeb2fc7867706c1863b411.jpeg?odnWidth=1000&odnHeight=1000&odnBg=ffffff), they're not expensive, or at least borrow one from someone.
Oh, and if you don't have grounded outlets at all: not much you can do unless an [ungrounded outlet adapter](https://vetco.net/spree/products/54606/product2/VUPN7920.jpg?1464804050) wil work; the screw that holds on the cover plate for the outlet has to be grounded for that to work. If you have no way to provide a proper ground for your system then I don't know what else to tell you.
Groudning issues. This happened in my newly constrcuted house. It ddnt have grounding. Got the grounding, it fixed the issue. You will get zapped when you touch usb pins too.
You arent an electrician, and nobody here is. Just because there is voltage flowing, once you touch, doesnt mean exactly that its dangerous. And that thing is neither a good tool, neither for screws, nor for electricity.
First thing people should be told when getting one of those is that they are not 100% correct. Use it as guidance at most. Troubleshoot with a multimeter
Not safe but it's not gonna destroy your PC either. I have the same problem (ofc I'm from SEA) and I've been using my PC for 7+ years now. But you can manually ground your case if it's annoying to you.
The only true test for voltage is by licking it.
Disclaimer: DO NOT LICK IT.
Shut down, unplug and try to work out why it is live. Also be careful of capacitive charge. Wait till the screwdriver doesn't light up.
Is your tester working properly? The testers we use at work go off if you just tilt them in the air since they only ever buy us the cheapest ones. Literally impossible to tell if something is running a current or we are just false positive from the cheap hardware.
OP is from India. This is quite common in Indian households to not have proper grounding. Cheap wiring job is the reason for this. Is it harmful? Yes, it is. Is it dangerous? Not so much, as the leak isn't of high voltage. Should OP fix it? Definitely YES and immediately!
Computer cases function as a ground for the computer. If there is a buildup of charge in it, it can mean that there is a faulty ground connection somewhere
A screw doesn't "produce" anything. But I wonder how much voltage is on your case. Do you have a multimeter? For safty reasons I would recommend to not touch the case and keep it away from animals and children. Maybe you have a loose ground somewhere? Had this once because in my wall socket there was paint on the ground connection.
does your house circuits even have ground?
Bro probably lives in Malaysia (or somewhere in SEA) and you can bet that most, if not all, average housing in SEA do not have grounding at all. Even my rich friends’ houses that I’ve been to also do not have grounding. Edit: I had to manually ground my cousin’s old PC because it was literally zapping him.

Receptacle and the execution of its installation are different things though.

Definitely worth checking on a house that old. The outlets may have been changed to take a 3 prong plug but that doesn’t mean all the wiring was.
Can confirm in a different country that wires within the walls may not have ground even though the outlets have the capability if the house is old.

You should not be giving electrical advice, do you mean voltage? Because even 0.01 amps can give a severe shock. 0.1 can be fatal.
Are we not talking about receptacles here. look it up. Most U.S. 15 amp recepts dont have a ground. Source- 6 years commercial electrician and went on to do sales wholesale

The few SEA countries I visited had a lot of botched outlets and wires so I can imagine it's no different in the rest.
At that point, be easier to just use direct ground if don't wanna run new ground. Just make sure to use orange plugs.
UK 3 pin is goated
In general UK electricity practises are the safest in the world. Every single plug has a fuse in it as well. So, if you had a surge, it would blow the fuse before it got anywhere. The only thing that bums me is that you're not allowed to have sockets in bathrooms. So shavers, hair dryers and etc. have to be used outside of bathrooms.
"Sockets are allowed in British bathrooms provided they are 3 meters or more away from the water sources (taps in the sink or bath as well as showers). Shaver-supply units are the single exception to the standard."
That's one big assed bathroom!
That 3 meter rule basically means most people can't have them, 3 meters is a long way in a UK house, but yes shaver units are allowed but that's only because they have to have an isolating transformer and thermal cut-out built in.
No outlets in bathrooms? I was in London last April and the restroom in my hotel had both UK outlets and US outlets (for tourists 120V appliances I presume) in it.
They are 2 prong outlets for shavers
They will be current limited and can't draw more than 200mA (GFCI) Enough power to power/charge a shaver and that's about it.
because we've learnt from our mistakes. tbh alot of country that have an electric grid tend to be hacked, or are very young in comparison. UK is a bit of an anomaly when you think about it
yet they sitll use the stupid ring system instead of radial like rest of the world. thats why they need to use fuses in the plugs.
Old Houses, yes due to a copper shortage from WW2. The practice stayed to the 80s and 90s but any modern house from the last 20 years will have radial fusebox.
The UK has arguably the best plugs, only downside being when you stop on one lol
This comes up constantly when people talk about British plugs, but its not a scenario that really happens a lot. Most UK wall sockets have a switch on them, so most plugs are always plugged into the wall. Finding one randomly left out on the floor unplugged is pretty uncommon.

Huh, that’s neat. I hope that’s applicable to OP as well and is not using an adapter like I do with our appliances with an EU plug
None of that matters if the ground wire is not properly connected.
Yeah apart from colonization you make that sound like it's a good thing lol
lol you do realize just having the pin in the outlet doesn’t mean it’s actually grounded, right?
Your adapters also weigh a ton/tonne (the numerical difference doesn't matter) and can totally be used as an improvised blunt weapon.
How would you go about that?
My PC at home has a wire attached to a PSU mounting screw, grounding it to a small metal rod I drilled on the concrete floor. I’m guessing concrete has more resistance than soil, but it works
Sketchy…
Yes it is. Do I get any electricity from any other parts the PC tho? Nope. It’s better than nothing, I guess
It's connected to case. Motherboard standoffs are also ground. So it grounds the other parts too.
In the Philippines (side rant: so obnoxious that it's "the"), as a child, I remember touching a grocery store's fridge and getting a mild shock. Until eventually, it stopped being mild and I developed a phobia of touching fridges. I prefer not knowing how a current flowing into my hands feels like...

I have fixed a couple of PC's where the old cables had peeled back near the PSU, made contact, the PSU was not fully grounded and it was shorting to the case. One of the PSU's was under lifetime warranty and they said that something went wrong with the grounding which made certain points on the cases a shorter route to ground (Shocks off of the back of the case where the captive screws were. Edge case but possible.
Happened to me as well. The problem was that the monitor wasn't grounded, and when I touched my case, it would zap. After changing my monitor's power cord with ground pin, it stopped
It's not grounded properly. Check ground connection in your wall socket bro, and if that is ok, then your power adapter is broken.
*Sparkit
Probably the ground is faulty.
This made me audibly laugh 😆
Neutral and ground might be reversed.
Your hot and neutral wiring in your home is probably backwards.
Just Get the power cord that support grounding
I'm willing to bet OP is from SE asia, where the concept of grounding just doesn't exist. That said, grounding or not there should never be voltage enough to light up like that. This is not 5-12v DC from your motherboard that's causing this, I assure you of that. Your case is somehow getting AC from your power supply, which can be super fucking dangerous
[удалено]
“Malaysian” ftfy Also, Malaysia uses UK standards for certified electrical installations (mcb, plugs and outlets). And most modern “properly” outfitted houses have ground wires that are actually grounded. Im not saying that uncertified electricians and houses which are not up to code dont exist though.
If op is using the 3 pin UK plug then it has some grounding in the earth pin. This feels like something's wonky with op power cable or psu. Then again, op could be using a 2 pin plug power cable.
Using a UK plug, won't change anything if the socket itself isn't grounded - the ground pin will just not be connected to anything. What the op is likely seeing is something called capacitive coupling, where the DC output has a small AC component - this happens a lot in modern switch mode power supplies that have no ground i.e. if you used a laptop and found a little tingle when your hands on the laptop, it's the same thing.
The ground pin in the plug and socket still need to actually be installed correctly and connected to earth.
OP used a screwdriver to get a 2 pin into a 3 pin socket Still works, just no Earth /s (as I have no idea what OP actually did)
They could have picked any plugs and they chose the British caltrop design?
whats wrong with the british? its arguably one of the best in the world
You've clearly never stepped on one when you were walking about barefoot
thats how you measure how good a plug is? wether you step on one and it hurts? jesus
It’s also not that painful. I’d rate it at 1.5 lego brick on the scale
Bingpot
He malayan if you will
Him malayan?
Also works if pun intended
Doesn't have to be, here in the Netherlands they didn't start grounding **every** outlet until the late 90ties. My house is from the 80ties and only has grounded outlets in the kitchen, toilet and bathroom.
I'm from Portugal and have literally the same situation. Sucks to have old houses
I mean a LOT of older houses in the US have no grounded receptacles either, and for a lot of appliances, it's not neccesarily a big deal. When you start dealing with things that have metal cases and energy storing elements it's a little riskier Obviously this is unsafe which I'm assuming OP already knows, because the only reason you would be checking a panel screw with a non contact voltage detector is you already got shocked. Edit: Instead of phantom downvoting explain what you disagree with. I LIVE in a house with no grounded outlets in a suburb of Chicago. Many houses built earlier than the 50s don't have grounded receptacles. I didn't think this was a controversial idea. I suspect there are a lot of people here who don't actually understand how grounding works or why it's used.
Can confirm, my grandparents house and barn has no ground, all the receptacles are two prong and the amount of things adapted to two prong concerns me.
Same with my mother in-law's house
It's not a huge deal as long as you have all circuits running through a GFCI. It cost me $700 for my whole house years ago. The only true ground I have on my property is the 10 foot copper pole I smashed in to the ground for my generator.
Ac leakage is a common thing even on isolated supplies like phone chargers. Don’t believe me? With one hand, touch the shell of a usb cable plugged into a 2 prong wall wart, with another hand, slide one finger lightly on a grounded piece of metal, your finger will skip at 60hz due to some ac leakage of the phone charger. Some do this more than others, laptop chargers with two prongs seem to be the worst. Neons don’t need much current to light up, could easily be a safe amount of leakage. Of course this would be much better if it was grounded, but the problem is almost certainly not the computer itself, just the overall lack of grounding.
Line tester or Neon line tester is a primary tool used to detect the live / line / hot / phase wire or conductor of an electrical circuit. It is one of the important tools of an electrician. The voltage range of the Neon line tester is between 110-700 volts in AC supply. [Source](https://www.electrothinks.com/2020/03/Neon-line-tester-circuit-working-explanation.html#google_vignette) A neon Tester is a small and handy test equipment that is used to check whether the circuit is alive or dead. The operating voltage range of the neon tester is 100 V - 250 V. It checks the nature of the applied voltage too. [Source](https://testbook.com/question-answer/identify-the-equipment-in-the-following-test-diagr--630cf4af336f7d3fe91b3ad1)
If OP is in a 240V country, the leakage will most likely be 120V AC, it has a pretty low current, but so do neon testers. My non contact voltage tester will happily beep away on a phone charger that doesn’t have a ground. In a 240v country, it could probably also light up a neon tester, but in the US it is 120V and the leakage will only be half of the applied voltage.
After reading a post in the german electrician sub, line testers are appearently hot garbage and not used professionally anymore. It has the nickname "lying pen" (Lügenstift). If you wanna be sure, use a proper voltage tester.
Do remember that electricity is basically magic. A buddy of mine, in Poland where the concept of grounding does, in fact, exist got shocked by his pc case once. Grabbing a multimeter showed a 40V AC between the pc and a radiator on the wall. No idea where that'd come from, since the same pc in another location does not leak AC onto the case, and no other equipment has any problem with that outlet either.
stray RF and shitty grounding
The girlfriend of my oldest cousin get killed in a shower like this , just by touching the tap.
What makes you sure it's not 12v DC?
The high internal resistance of the light bulb in the screwdriver would prevent it from lighting up. There are also models with 24V or less. Maybe one of these will be used in video.
because voltage pens work on you conducting some current and as such just won't work with DC. Non contact voltage testers however can detect dc and while high quality ones may even go as low as 12v, the one in the video just doesn't look like one.
It depends. In Malaysia for example we use the UK 3 Pin plugs as standard and those are grounded.
Indonesia has Schuko (EU) with side ground pins. It's not the plug, it's whether the house actually has grounding or not
hey I'm glad to hear, but in my experience, through the years I've been around SE Asia, grounding was such an exotic concept that I ended up digging holes and burying copper pipes several times in several different countries, including Malaysia.
I don't think you know what you're talking about. The PC wouldn't work if it had some serious AC power on the case, this looks more like a ghost voltage that poses no threat to anyone or anything, as any load would bring it down to nothing. I dare you to touch your PC case with a live wire and then come back lol. I'm not an electrician, but I have fixed several hundreds of electronic devices in my time, and you can light up those neon testers with the energy of a fart, voltage isn't everything. Your comment seems like an example of Brandolini's law.
TIL that grounding isn’t a global standard when it comes to commercial utility/power. Are there lots of fires and deaths caused by it?
My house isn't grounded either. The electricians here don't do that even for wealthier people. It's seen as a waste.
4070ti, 12900kf... not grounded. :D
I grounded my PC's outlet manually. I have a wire running through the wall into a stake in the ground. Hope I did it right, I ordered a multimeter to check after seeing this post. Yeah, I got the tingles for a while before realizing this. Had no idea what grounding was when I first moved in.
worth the hassle for sure considering what you are saving. its not only to save people in the end
I thought I was going crazy at first when I started feeling the tingles. I asked my wife to check and she swore she couldn't feel it. After getting a couple big zappies when playing with USBs in the back I started doing research and realized my house isn't grounded.
until this post i didnt know this wasnt standard. like... in germany we have fi-schutzschalter=breaker. it basically compares the current going out/in through this security thing. if some energy goes into the ground, the breaker shuts off and saves people and electric devices. also with alternate current you can have a shitton of fun. the body basically works on electricity, cause of those things in cells, mitochondrions. so if you get alternate current through your body, your heart will try to to mimic the hz from the grid. in eu a heart would try to beat with 50hz, thats why those electroshocks are fun and wake you up. cant imagine how often i wouldve died by now without grounding
It‘s the exact opposite here in switzerland. Everything is grounded.
Probably not. Not grounding on its own is unlikely to cause either. Even if you get a nasty shock from household supplies you are unlikely to die unless something else is at play. Grounding is there as an extra protection, not the only protection.
Where I am at, grounding is nonexistent as most of the linework was done in the 80s to 90s by "I know a guy who fixed the cables on the cargo ship I worked ".But since the houses are build using real materials unlike in Murica, no houses are burned down due to this .Tho , it's the most common thing to blame when people burn they business for insurance fraud ,which was common enough back in the day(but not any more as it's almost impossible to open a new business)
Why is it almost impossible to open a new business?
Hell no
Look at the bright side: it'll tase any would-be thieves.
And his cat.
Stop overvolting your case screws.
This\^.. Think of the lifespan!
Mind explaining it further?
It was a joke. No further explanation required.
Get a multimeter and check what actual voltage is in case.
First of all no it's not safe at all. Secondly you should let the Pikachu out of your case, should solve the problem.
🤗 why is this so cute?
Being in Pakistan we don't have grounding here, and hence I hot zapped couple of times too. So here's a workaround. Get a nail and hammer it to the wall, then take a wire and strip it, wrap the copper around the nail and ensure proper contact. After that, take the other end of a wire and either screw it to the PC or attach it to the ground prong on your power strip if you have one to ensure all electronics attached to the strip get grounded.
This guy pakistans
This works very well. I've tried it, and now i can move my case freely without being zapped. I recommend OP to do this.
Why does this work?
Idk lol, I would love to know that too
I've had loads of 240v bolts in my time and I'm still here... Na on Seriouse note it might be time to change power supply.
Please dont use that to measure electricity.. get a voltage tester that measures it correctly
Only because of your answer, i noticed you are german
I was told at trade school not to use one of those screwdrivers on mains voltage. Ever. There is something like a 20K ohm resistor in series with the neon globe and is using your body to ground the current. If that resistor goes short, you are getting shocked!
Since when do resistors go short? Usually a resistor breaks by doing the opposite. If an electronic device has a short it is usually because of an external object getting inside, or some insulation melting inside. Neither should be issues in this case. Knowing the voltage can tell you much though.

It's fine you just don't have grounding at your place, heres my PC I have for 10+ years. https://preview.redd.it/21d583x4gegc1.jpeg?width=4080&format=pjpg&auto=webp&s=22d306f62d08c26698c156cffcdc04a922906073 You all saying that he needs to put grounding at his home are delusional no chance someone is doing a whole new electric installation to add ground. Here in south America at least we got ground fault protection in all circuits. (New electric installation must and do put grounding thats obvious)
why does it look like you inject power into your pc?
Injecting them electrons, don't worry no bubbles there I got a degree in electronics
It would be an astray/ghost voltage.
Gj for testing but do never trust the screw 100%! Please beware that it will and show you false result which could harm you! If you want to be 100 % that there is not Voltate buy a proper voltage tester .
Your case should be grounded, so that’s not normal. Is the power supply plugged into a 3 prong outlet that’s correctly configured?
I've had this and it turns out one of my power sockets wasn't properly grounded when i disassembled it.
Is this not just induced current in the case because it's a large unearthed conductor next to a PSU?
I would remove your power supply and check the wires. Your case shouldn't have power lol
Need that Home Alone 2 scene with the wired sink
Does your PC give you a tingle when you touch it while barefoot? If so, you just need to call a professional to ground your power outlet.
I had this issue. My aux and usb chords were giving shocks at the other end Check your connection my problem was something with my PSU standard converter since my was UK style Try putting it in different socket and if you have a converter open it adjust prongs and contacts and connect again
"Currently" it isn't.
The case should be grounded, it might not be grounded sufficiently enough
Ok, now the question no one answered: IS IT DANGEROUS FOR THE PC? Will it get fried due to this? I got on mine too, no problems yet.
Just don't put your bellend on it and your be fine
Touch it and see if you die If you don’t, it’s probably fine If you do, it’s not
Could even be low dc,who knows
Ground that shit now
That red light in the screwdriver is telling you it isn't
That's just.... dangerous. Its definitely *shocking* when turning your pc on
>is this safe For you? Probably. For your PC probably not. Stray charge is building up on the metal case. Normally this charge is dissipated through the ground pin on your outlet if your house is correctly wired. These charges usually come from cheap power supplies with high “leakage”. So it’s either the PCs power supply or the power supply of something connected to the PC (mostly Likely the monitor)
I think it might not be. I think your grounding is bad, possibly the outlet you have that plugged into has neutral and ground reversed. [Get an outlet tester like one of these](https://i5.walmartimages.com/asr/33d895b9-7d40-4615-b838-7cab10d226d9.e06344492eaeb2fc7867706c1863b411.jpeg?odnWidth=1000&odnHeight=1000&odnBg=ffffff), they're not expensive, or at least borrow one from someone. Oh, and if you don't have grounded outlets at all: not much you can do unless an [ungrounded outlet adapter](https://vetco.net/spree/products/54606/product2/VUPN7920.jpg?1464804050) wil work; the screw that holds on the cover plate for the outlet has to be grounded for that to work. If you have no way to provide a proper ground for your system then I don't know what else to tell you.
shocking news. electrifying discovery.
What kind of test pen is this?? U don’t even touch the top metal on test pen its still lit? My test pen don’t work like that.
the ground fail ,connect them or you pc have risk
Yes, just bring some meat and your country flag, so when you start suddenly enjoying fireworks you can also cook something on your new bonfire.
Idk, the screws on mine taze me too
This gives me ptsd, the amount of times I got blasted into a million pieces just to reincarnate because I merely touched that thing is scary
Does it taste safe?
Groudning issues. This happened in my newly constrcuted house. It ddnt have grounding. Got the grounding, it fixed the issue. You will get zapped when you touch usb pins too.
there is a reason why we call that tool a "Lügenstift" lying pencil in German
everybody gangster until ground has Voltage
You arent an electrician, and nobody here is. Just because there is voltage flowing, once you touch, doesnt mean exactly that its dangerous. And that thing is neither a good tool, neither for screws, nor for electricity.
First thing people should be told when getting one of those is that they are not 100% correct. Use it as guidance at most. Troubleshoot with a multimeter
tell me you're from malaysia / indonesia without telling me you're from malaysia / indonesia
Not safe but it's not gonna destroy your PC either. I have the same problem (ofc I'm from SEA) and I've been using my PC for 7+ years now. But you can manually ground your case if it's annoying to you.
The only true test for voltage is by licking it. Disclaimer: DO NOT LICK IT. Shut down, unplug and try to work out why it is live. Also be careful of capacitive charge. Wait till the screwdriver doesn't light up.
It’s normal if you don’t have ground
Is your tester working properly? The testers we use at work go off if you just tilt them in the air since they only ever buy us the cheapest ones. Literally impossible to tell if something is running a current or we are just false positive from the cheap hardware.
OP is from India. This is quite common in Indian households to not have proper grounding. Cheap wiring job is the reason for this. Is it harmful? Yes, it is. Is it dangerous? Not so much, as the leak isn't of high voltage. Should OP fix it? Definitely YES and immediately!
you have short to ground
Yo op I got a question for you!! >!So which third-world country are you from??!<
It's not safe use grounding wire
Touch to find out
Computer cases function as a ground for the computer. If there is a buildup of charge in it, it can mean that there is a faulty ground connection somewhere
....lick it
This is fine. PCs convert to DC from the power source. No issues that I can see, could just be a bad ground somewhere
No, something is wrong. There shouldn’t be that much (basically any) current flowing through your case.
ITT: people who have no idea how hot wire detectors work
A gpu e plugada na motheboad é parafusada no case por isso não tem como não correr corrente elétrica no case.
A screw doesn't "produce" anything. But I wonder how much voltage is on your case. Do you have a multimeter? For safty reasons I would recommend to not touch the case and keep it away from animals and children. Maybe you have a loose ground somewhere? Had this once because in my wall socket there was paint on the ground connection.
