Try the GTX 680 in an entirely another PC ( like a friend's rig or something ) and see if you still have the issue.
I'm sure everything is connected properly, I'll try testing in a friends rig and I'll try taking the GPU out.

I mean it's just screwed into my motherboard tray from my case, and that is sitting on my desk.

I'm fairly certain the PSU isn't the problem, as it's brand new and I've tested it with another one. Wouldn't seem logical that both of them are broken...
