I just upgraded some components in my PC, I got the Evga 550 GS Supernova PSU, the CPU cord doesn't quite reach my ATX 12v 4 pin connection unless I stretch it hard which I won't. My question is can I use the VGA plug on the back of the PSU for the CPU connection since it's the same 8 pin plug? If so I can reach it but will it even work that way?
