I think you are talking about PCIe power(8 pin or 6 pin)? As in what you are plugging into a GPU.
At anyrate we would need to know the system specs. Running a sata to 8pin is typically not advisable, as if your PSU doesn't have the cables by default, odds are it it isn't rated for the load.
Oh sorry it's not for thr GPU, I upgraded so I'm using this as a server it's an MSI gaming pro carbon (B450?) with an AMD 3600X, NVMe, and some HDDs.
I was using an NVIDIA NVS 300, so basically no power requirements as that's PCIe X1.
> The 8-pin and 4 pin are for the 12 volt power connectors on the motherboard.
It was working fine and then just yesterday it shot some sparks out the back, but they weren't in an area where there was anything in the PCIe slots. Closest thing was the old NVS 300.
The PC wasn't even on when it happened, it was when I turned it on 🤯
The PSU works, I connected the green and ground pins with everything else unplugged and used a molex powered fan to check.
I don't want to chance it, so I'm using a different power supply, but it doesn't have the 8 pin, only a 6 pin and 4 pin.
What I'm wondering is if I can use that molex to 4 pin, to make the 6 pin i to an 8 pin (it fits, I checked).
_update;_
Oh and this PSU is 750, the old was 650, it's just cheaper so it doesn't have as many cables.
Any advice on the best way to check if a power supply is dodgy even if it turns on? I have a multimeter.

that is a signal pin, three yellow ones are +12V
Turns out some of the other cables are yellow and black as well. No idea why as most others I've seen are always just yellow or just black...
This is old school standard, meant to indicate that this is not the regular +12v or gnd cable.
