And you're probably looking at steady state, when you first power on  
and all your fan and drive motors are starting at the same time, and  
capacitors are charging up, you may well be loading more than an  
extra 100 watts for a brief period.

As another poster pointed out, sometimes it is the quality of the  
power as much as the quantity. PSUs included with cases can tend to  
be low quality, and they start to throw glitchy power long before  
they reach their absolute wattage limit.

I think Antec makes some good PSUs (and nice cases, there are  
exceptions to the included PS rule).

An item that most users know nothing about and hardly know is in  
their case is a golden opportunity for builders to skimp. The only  
way to get a really good power supply is to specifically demand one  
or purchase it yourself.
