Well, that's just silly. There must be something wrong with your
figures because even a decent 380 watt PS is perfectly adequate for an
ordinary desktop system.
For instance, I make an 80mm case fan to be 12v x .15a = 1.8 watts.
Are you figuring startup current as your steady state? That would only
apply to motor driven parts like fans and drives. That's momentary and
the other components aren't drawing anywhere near peak when it happens.
And what x86 CPU uses 150 watts? Max current for an AMD X2 is 89. Some
of the Intel quads get as high as 130...

My figures are closer to 250 peak 180 steady state... So a
300-350w power supply should be fine for normal usage...
