This might seem like a newbie question but I would really use your help. I just bought a bought a gtx580 and a Corsair CX600 PSU. I can't seem to be able to connect the PSU to the motherboard ( Gigabyte G41M-E2SL ) for the following reason: The PSU doesn't have the 4pin cable (ATX 12V or something). Are these 2 even compatible? (The motherboard and the PSU), is there something that I can do? Please help me.
