The most important part of the PC is the power supply, as it provides the power needed t operate the other components of the computer. For power supplies, almost any power supply will do. The only things to keep in mind when selecting a power supply are 1. Compatibility and 2. How much power your computer will need to operate efficiently. For today's advanced gaming machines, we recommend at least a 350 watt power supply. However, always make sure your power supply can handle all your system specifications. In the event your case comes with a power supply, you don't need to bother getting one.

     What is all comes down to is this simple equation, power needed by your computer should always be less than the power provided by your power supply. power needed < power available. Just follow that simply equation and you will be ok.

    Finally, here are the power supplies we recommend. (an yes they are all Antec power supplies)
