Power consumption?

[JeppeVJ]

HI there

I Recently built a pc for my little brother, made of spare parts. It consists of a athlon 64 3000+, Ati x800gto, and 1.5 gigs ram.
I have considered buying him a new graphic card, more precisely a Geforce 7900GT, but his psu only runs at 250 watts. Is it possible to use the system with such a powerful card without frying the psu?

Thanks, Jeppe.

If its a quality psu i dont think u will get any trouble, but its hard to say. Many old PSUs have all amps at 3.3+5volt lines.

I see. It appears to be of good quality(Very heavy)

Thanks, Jeppe
