420W PSU - enough for a 7900GX2/7950GX2?

[GingaNinja]

I was wondering, is it possible that a Hiperpower 420W could power one of the cards? Its specifications are somewhat lower that those recommended by Nvidia, but I was wondering whether I might just get away with it. I don't have much running in my pc (see sig below); I'm also running watercooling on the CPU, but this is powered directly from the mains, so it doesn't make any demands on the PSU.

If I were to try it and the PSU wasn't up to it, could any damage result or would the system just not power up or be unstable?

I would imagine not as they're basically two cards in SLi.

I would be inclined to agree..

I would also be inclined to ask Úlfhednar if you finally decided to upgrade your X1800XT?

Doesnt the 7950GX2 use something like 200w at load?

If you want to be on the safe side, check NVIDIA's list for compatiblity of PSUs : http://www.slizone.com/object/slizone2_build.html#certified_powersupplies

Not decided yet. I'm either buying an X1800XT to replace the one I killed or an X1900XT. Depends on funds etc.
