My Emachine used a Bestec ATX-250-12e power supply. Do I need to use the same brand and model? Or can I just get a generic ATX 250 watt power supply?
As long as the power supply fits the case and has the proper connector it will work but do yourself a favor and purchase one with a higher wattage output. It sounds like the original crapped because you have added peripherals and the power supply no longer can handle the load. The higher wattage rating only designates the amount of power the supply can put out. If anyone tells you that you cant do this they are full of crap and need to stick with fixing sandwiches...
