Power supply
The power supply is a critically important component inside your PC. Without it, nothing gets power. It is the central nervous system of the whole machine. The main differences in power supplies of the correct type are the wattage rating, and a bigger number means more power. You'll see 350W, 500W, and others. Contact your local tech head to verify how much is overkill if you're upgrading or building your own system and aren't sure exactly what you need.
