I recently set out to finally buy and build myself my very own PC. Something I've wanted to do for a while, but I've hit a wall here. After hooking up everything, my motherboard, my GPU, Power supply, all of it, the computer absolutely refuses outright to display on any screen it's hooked to, in any basic way, shape, or form. I was looking to see if it may be something to do with my GPU, but After looking into it, the way I have it wired up should be fine. I have no idea what I'm doing wrong and am absolutely confounded. Components are an EVGA X79 Classified motherboard, MSI GTX 760 TwinFrozr, And My Power supply is a Corsair CX600 M. I've seen some people say that when wiring a 760, you need two separate cables going from the PSU to the GPU, but I've also seen that if you have one cable with two ends, you can use that and it will work just fine, which is how I have it wired. 8 pin out of the PSU, and 2 6+2pins going into the GPU. Any ideas?
