Actually, I think it may be less then that. Peak power consumption for an i7 system at 3.8ghz with the exact card is 382w for the whole system, so I should be fine, maybe about 350w

Am I correct in thinking.

9800GX2 + C2Q Q9550 = GTX295 + Athlon X4 635

Here are various reviews of GTX295 showing power drains:

Neoseeker - BFG card
Geeks3d - Reference GTX295
Toms Hardware GTX295 - GTX275 sli comparison

Each one of these shows GTX295 around 310 - 330W

I would say a new supply is needed - Corsair TX650 would be on the mark.

+ check out this link to get a better judgement, it will help you decide what power supply value is needed:

I ran the calculator for you,

Athlon II 635 @ 100%, GTX 295, High End motherboard, 2 sticks of ram, 2 external USB devices, 10% capacitor aging + 100% TDP

All this gives 642W usage
