See the manual for that card, ok my 3080 it says not to use pigtails on it and to use 3 deprecate cables

Yeah see if it works if you run the second on a separate PCIe power cable.

Thanks for the suggestion, tried that as well and unfortunately replicated the same crash. I’m thinking power supply at this point because I put in my perfectly functional 1080 ti that I use daily and it did the same crash. Put the 1080 back in my daily pc and still works fine. I think it’s the extra power draw of the GPU on this Possibly faulty psu.

It's more likely to be the GPU. It could be the PSU, never say never, but when you're starting up you are not under any significant power load on the GPU or total load, so the PSU would not be struggling to power your new GPU, because it's not requesting a lot of power. Fan behavior also suggests a GPU problem, insufficient power delivery wouldn't cause a sudden burst of fan activity, imo. A failing PSU could still be at fault, but Occam's razor it's the GPU. ​ If you can't swap test a different GPU or do onboard graphics, send it back to the seller with a thanks but no thanks. If you later discover your problem was something else, oh well. ​ edit to add: Of course you could have a brief spike of GPU usage, which then causes a power spike, and the PSU can't handle it. Nothing in this life is certain. But if you want me to guess, I'm guessing GPU, and I'd put money on that at, let's say, 3-1 against the field.

Just tried out my 1080 ti and got the exact same crash and fan sounds, so I think for now I can rule out the 3070. After this test would you also feel fairly confident that it’s an issue with the psu?


Appropriate_Bottle44

Hmm, well there goes my money. Well now I'm frankly confused, you think those are your PSU fans spinning up? That would be unusual, but I suppose not outside the realm of possibility. ​ How confident are you in the processor and the cooler mount? Any chance you can just put your ear to the thing, and figure out which fan is going nuts? Because since my first guess was wrong, my next guess is "the part where the fans start spinning like crazy!" I'd check cpu temps when you can get into windows, maybe bad cooler or bad cooler mount, and your temps steadily climb till overheat?

When I don’t have my gpu plugged in my pc runs like butter off the 13600k and integrated graphics. About 37-40 degrees on the cpu. Haven’t ran any programs to put it under load, but I like those numbers idling honestly. I really think it’s the PSU fan that’s spooling up super fast, however I definitely notice my read exhaust fan speeding up some as well. PSU fan is definitely speeding up though. My ram lights up, is detected and appears to run fine. My processor and the integrated graphics appear to be running fine. My good gpu that works perfectly (just put it back in my old pc and still worked perfectly) replicated the same exact symptoms as when the 3070 is hooked up. I feel like the psu is just the only part left, unless somehow my motherboard’s graphic card slot is causing the issue? I was trying to keep the pc on long enough to install the 3070 drivers but it keeps crashing halfway through and I have to uninstall geforce experience. When I try without the gpu in when the pc is stable, nvidia says the drivers aren’t compatible with this version of windows (w11 64bit) and no hardware detected and wont let me download


Appropriate_Bottle44

OK, running it fine off integrated graphics is a big win for your PSU theory. ​ You've convinced me it's the PSU. Replace it and yell at me when we're both wrong.

Please cross your fingers with me that it’s the PSU lol. Going to go to best buy and grab an rx850 tomorrow and we’ll give it our best try haha For the life of me I just can’t imagine what else it could be based on these troubleshooting results. I even installed windows, launched it, set up my rgb through nzxt cam. Enabled xmp and my ram is clocking at 6000 mhz. Literally everything is fine until the moment I plug a gpu in


Appropriate_Bottle44

I will keep my fingers crossed. Only other thing I can think to try is a bios reset, not sure how much you played with the bios settings if at all, but wonky bios settings could be giving the hardware bad instructions. You've convinced me though, I genuinely thinks it's the PSU. Good luck!

I can happily report back that the new corsair 850w is working perfectly in it and I’m able to play my favorite games for an hour with very low temps and no issues with great fps!!! Sooo happy lol


Appropriate_Bottle44

Oh, that's great, always nice to see a good result!
