Vram's explanation sounded good to me. I'm really more of a digital
guy :-) That said, I think your 100-150W number is reasonable. Most
power supplies are rarely run at anything near their rated capacity.
The extra headroom is a good idea though. Modern processors can go from
idle (<5W) to full tilt (> 50W) pretty much instantaneously. System
power up can also tax the supply, particularly if drive spinup isn't
staggered.
