Reading the box on this GeForce 8800 GTX, it says it requires 30 amps on the +12V rail... now, reading the specs on the 650W psu I also just bought, it says that +12V1 is 20.0A and +12V2 is 20.0A.. are these combined to a total of 40.0A for the card, or am I mistaken? Yeah, I don't know much about PSU's
