Of course it might be a few watts off, but it still gives a good idea about general wattage requirements.
n what? The PSU doesn't burn juice for nothing. Only for what's needed. It can *provide* up to 1000W, it doesn't *consume* 1000W by itself.Last edited by V!NCENT; 24 August 2009, 11:16 AM.

you are still doing it wrong! The watt on the package are about the OUTPUT not the INPUT!
650W PSU = 650W on the package and on the system side, but it sucks 812W from the wall socket.
In your case a 650W PSU would be way more than enough.

Also, one thing you get wrong is that PSUs have the best rated efficiency at certain loads. For example, most high end PSUs have 90% efficiency when the load is higher than 80%. If the load on the PSU is lower (way lower in Vincent's case) the conversion efficiency is even lower.
Read some basic electronics and figure out what happens inside a power source.
