the PC currently. Also how many physical drives, Optical Drives
and does it have any type of High End Video card ( 512+ Megs
of Video RAM ). Gaming Video cards exhibit a very high load

Power Supply quality is all over the map, so if you decide to get
a new supply don't buy the cheapest unit on the shelf and be sure
it's compatible with your specific motherboard. Not many things
worse than a return trip to the store to get a swap for the correct
part.
