I agree. I had a good ( $60 ) 350 watt power supply with a
'silent' fan.. I ran it with a P4 3.0ghz board and 5 3.5" drives
and a DVD... no issues what so ever. Drives use 10 watts max
when they are really busy.  ... this was on a server so I didn't have a
'fast' graphic's card... not sure how much juice those things draw.

if you system is flaky... I'd look at other things before I looked
at the power supply.
