Re: power supply
What exact model of graphics card is it? You can have an 8300GS which consumes like 0 watts and an 8800ULTRA consuming 315 watts .
And besides, you also have to look at your 12v rail[s] as well and combined amperage.
Maybe give us the case model and we can get some more info on that PSU, but it's probably garbage if you want to run a high-end graphics card.
