The colored cables are the original ones from Corsair (AX860i) - nothing changed since my last build.
During all the previous tests only the top GPU was plugged in. Even tried switching off the unused PCI-E lanes.
Normally I have only the 24pin and 8pin connected (same as in my last build). But to be save I tried connecting the 4pin also - with no effect.
I also tried the other GPU now - but still the same code 61.
Is there any way to narrow it down which component is faulty? (RAM or board)
Bought every component at a different retailer, so I'd like to know which component I would have to send back.
This is only if you are out of ideas of course - would be glad if there is something else I could do.
