I upgraded my Power Supply on my Computer to a Cooler Master 460W Power Supply since the previous power supply on my PC looked kind of fishy since it is made by Bestec which seem to fail a lot on emachines according to a lot of people online and was a 250W PSU with 20 pins plug into a 24pin Mobo connecter.
I love my new Cooler Master Power Supply. It is quiet, uses less power because it is more efficient, and I have not have one power supply over heating or power related problem with my PC for a few month since replacing my old PSU.
You can learn how to replace a power supply by watching some videos online on youtube, or meta cafe.
Safety first, Unplug the Power supply from the wall outlet then you have to do is remove all the power supply molex, floppy, and 4 pin plugs attach to the inside of the computer’s mother board, expansion cards and drives.
