PSUs for Vista machine/DirectX 10 Graphics cards

[Stripe]

hmm, not sure if this should be in graphics cards but anyway...

just wondering whether anyone has any idea what sort of wattage PSU one will need for a vista capable machine and DX10 graphics card?

im debating whether to stick my current one in a low-spec PC im building or buy a low power PSU for that and keep my current one for when Vista comes out.

cool, thanks. I hear that a mid-range PC doesn't use anywhere near as much power as the PSU describes so I'm hoping I'm gonna be ok for a bit.
