a Core 2 will use at least 10W more power than a 45W X2 when idle.
source/ref? unlikely as E4500 etc only use ~8W at idle.

you do not need 400W. your current components draw 200W maximum. I would recommend Corsair VX450. if you will upgrade graphics, maybe Corsair HX520W. this is quiet up til 300W, even if your next graphics draws 2x more power than 8800GT, still less than 300W.

I guess I was really trying to ascertain what drawbacks having a needlessly overpowered psu would bring. there aren't really any, apart from the extra noise (the fan in a 1000W unit will be a higher-speed model to deal with the huge amount of heat at full load; that's rarely good for silence).

Does an intel board + celeron consume less power than a nvidia board + sempron? no is my guess. in theory TDP of Celeron 4X0 is lower, but intel chipsets tend to be power-hungry, so it evens out. when we're talking about idle below 50W, you get diminishing returns, so in any case it's only a handfu...

you don't need anywhere near an 850W PSU. your maximum draw is ~200W, at that DC output Corsair VX450W is still at lowest noise level.
