I am looking to upgrade to a better gaming machine. I just need to know whether my current PSU needs will be enough to run an 8800GTS 320MB or 640MB graphics card.

Its a Thermaltake Silent Purepower 480W (Xaser III) PSU. It has 3 12v rails and I think each supplies 18 amps. Will this be sufficient?

I want to run it with a 250 gig hdd internal, 500 gig external, 1 dvd writer, and 2 gig of ddr2 800 ram.

480W/12V = 40A MAX on the combined 12V rails and a powerful 8800 or x2900 wont need more than 30A on the combined 12V rails so obviously it will do.

Edit:

WHAT?? This psu is CRAP

There is only one 12V rail of 18A.. Forget it the max would be something like a x1650xt maximum


Ok, my PSU isnt exactly like that one, but if the specs are similar then I suppose I will need a new PSU. Its just that I thought that if maybe each 12v rail supplied 18 amps then I would be able to use 2 of them for the 8800 (it has 2 4pin molex connectors right?)

Yeah I just took it out to have a look at the label. It only seems to have 1 12v rail of 18 amps. I suppose the 6800 GT im running now must not need that much. Looks like i will indeed need a new PSU for my new system if I want an 8800GTS, which I do LOL!!!. Thanks for the help guys.
