I have a gaming PC that is causing me some problems. The GPU is an XFX XXX RX580 and the PSU is an OCZ500MXSP. I got the PSU for free, but it didn't have all the cables. It was missing the 8 pin PCI-e power cable that the GPU requires. It instead had an 8 Pin to 6 pin PCI-e power cable, that I connected to the GPU with a 6 pin to 8 pin adapter. So the GPU powers up just fine, but it's only powered by 6 out of 8 of the pins from the PSU.
Games crash a lot, particularly while playing PUBG. It happens sometimes while playing Overwatch as well, but it happens less frequently on Overwatch. I have also seen the blue screen of death, which I think is related. Could these crashes be caused by the GPU having the wrong plug to it? I just want to make sure before I spend the money on a new PCI-e power cable. They seem to be very hard to find since it is a rather old PSU.
Other info:
CPU: Intel i5 5700k
SSD: Samsung EVO 250GB
Plenty of case fans, so I don't think it's overheating.
I'm running an ubuntu VM on the same system, but it seems to crash regardless of whether or not that is powered on
Edit: this picture: https://imgur.com/a/GIBvRx8 makes it look like the two pins that aren't connected are both GND, so it may not be undervolted at all
