About the device inside your computer that changes house current into the type of electricity your computer components need.
EVGA 500w Power Supply

The power supply, which may come built into the case (but usually isn't), provides electricity in all the various voltages needed by the other components in the case. I remember cases with 50-watt power supplies, but I doubt those would even power the lights on a modern case, much less the other components. I've chosen a 500-watt power supply for my new computer; they make even bigger ones. The largest consumer of electricity in your computer will be the hard drives; so a network server (which might have 5 or more hard drives) would need a larger power supply than a mini-ATX with just one.

If you are building a computer, you'll be happy to know that all generic computer power supplies fit any ATX form factor case.
