It has to do with your components. Nothing in existance can use all the power that 1200watt psu can pump out. Power consumption would be only a little more than if you use a 800watt psu. Higher wattage psu tend to be a little less efficient on lower load, thus, the small waste.

also, it may be rated at 1200W but if your system only needs 600W that's all it will draw.

well, that is, not taking efficiency into account ;)

Kind of useless to get a 1200watt psu, since most components don't draw more than 700W in total.

1200 watt is way overkill.
But it won't "use" any more electricity than your components will draw.

Are you sure? How about a Quad SLI 9800GX2 + 8 HHDs + Skultrail with top of the line CPU (2*QX9775)? :lol:

Nope, I'm sure you can still pull it off on a 1000watt psu. :na:
