So I just installed an EVGA hybrid kit (1080/1070) onto my GTX 1080 ti, the 1080 ti was working fine for months now and so has the psu. But now when I go to boot the system with it plugged in with the PIN connectors the PSU will click once and not boot at all. Tried to boot with just the card in but no psu cords and it boots just fine. I have come to the conclusion it's either the PSU or the GPU at this point. I have a 750w PSU EVGA gold rated and even tried the 850w in my other rig with no success when plugged into a PSU.
