I received 6 boards recently and 4 of them have been working fantastically.

Two aren't working so well. After some troubleshooting I figured out that I plugged in the 8-pin CPU power instead of the 6/8-pin PCIe power.  Sad

Looking at pinouts, the 12v and ground pins are swapped on the two meaning I powered up two of my boards with 12v and ground lines swapped.

I'm hoping I've managed to blow a relatively simple to replace component and I get these boards working. I can't seem to find any schematics so I can try to narrow down what components are most likely to be failed.

Have any schematics been released yet for the BitBurner XX?

How did it even fit? aren't the plug shapes different for just that reason? No schmatics, but you can trace the ground (which you fed 12v into) and follow it on the board. I don't have my boards infront of me, but it shouldn't be too hard to trace. I think there are smd fuses on the board, so I would test them first.

The plugs are keyed differently, but the BitBurner XX boards (at least the ones I have) used connectors that are keyed to allow both types of plugs. I'm not sure why burnin decided to use these parts instead of the ones keyed only for the correct PCI-e power connector.

Aside from how it happened, it did and now I'm trying to figure out how to fix my boards Smiley
