I'm not sure if it's my motherboard or something else causing problem. Two of my video card died already (2 GTX 460 2WIN and now 1 GTX 470). I did research to find what I can do to fix the problem, that's why I changed PSU, and I tried 3 of them but no luck. I got my specs below to look at. I haven't been doing a lot of stuff on my PC, I do video edit but this month I never did, still my cards died. Gaming, not much but not at high settings (play at 1280x720)and maximum of 1hr game play. So should I RMA my motherboard or this is STILL normal? I want to make sure. My motherboard boots ok, no beeps every time I turn it on or anything.
One of those power supplies should have worked. And the voltage range of 11.73-12.097 is well within the spec of +/-5%. I would sell the evga card even if you get another one from an rma request. Try something else.
