i screwed my pc open and just wrote what is on the power supply
it's an antec model BP500u
ac input:100-240V~,8-4A,50-60 Hz
anything else you need?
Namely, the power output, in amps, provided on the +12v rails. On your PSU, there should be TWO such rails.
However, by my guess, each rail probably has 14-16 amps anyway, for a total of around 30 or so; that's 360 watts of +12v power, which is plenty enough to handle your CPU and video card. This guess is reliant on the fact that it's an Antec power supply, which is known as one of the better makers of PSUs.
–500 Watt or greater power supply with two 75W 6-pin PCI Express® power connectors recommended (600 Watt and four 6-pin connectors for ATI CrossFireX™ technology in dual mode)”
Woot I just sneak in there for crossfire (610watt PCP&C silencer) I've been wondering if I was going to be able to do that. Hopefully with a quad core (Q9450) 4gb ram, WD velociraptor, Seagate 500gb SATA and a few case fans I should be alright.
