Hi, I recently picked up a Asus p5k mobo, gtx 570, 8gb ddr2 and a core 2 quad with some generic looking aftermarket cooler for a steal and I was wondering whether a Corsair builder CX500w I have around would be enough to power this? It is a 80+ bronze psu so it's no generic brand but I'd rather ask here first that to risk it even if it was all cheap components.
