I've recently made a mining rig, with dual 1.3kW powersupply, and 6 Strix 1080's, everything was working perfectly fine :

until recently, a power surge occurred and 3 GPUs that are connected to the other powersupply became undetectable by the OS, and have different light colors than the other other 3 that are connected to the main powersupply.

At first, I've suspected that one of the powersupplys stopped working since i'm supplying 3 cards with each PSU, and I have confirmed my analysis by connecting 1 of the affected gpus to the "working" powersupply, and it became detectable, and started working perfectly fine.

I thought i could fix the whole thing by ordering a new powersupply and replacing it with the broken one, and that i did.
Unfortunately, after replacing it, the same problem still exists, i'm starting to suspect that something else might've been damaged from the surge, such as the powersupplies connecter (i'm using a lorentzen add2psu)

but other than that i'm out of ideas, can you guys help me?:D
