I have 2 80x80 case fans,hard drive cooler(3 20x20), video card fan, fan on chip set, 2 CD-ROM drives all on a 235w Power Man. No problems yet. Thinking of getting a 300w Sparkle. If you do get a new power supply make sure it is a good brand and on the AMD list. Their is a big difference between a good power supply and a bad one.
