Depends on Video card, and numbers of all types of drives.

I have a system that runs an AMD 1700+ a 32meg cheap
video card, two IDE HDs, a CD-Rom and DVD-burner,
with "only" a  300W PS.
Be carefull of the distribution of the 300W though to the
various voltages. Mine is an Antec PS that came with a
"non-performance" case.
