Power Supply Information

The power supply is what converts your AC power from the outlet into usable DC power to your computer's components. The wattage rating on the power supply is an indication of just how much power the unit is able to provide before being overloaded. Having more and higher-end components in a system usually means a higher wattage power supply is necessary, but to help you make the best decision we have designed a power supply calculator that you can see on our custom configuration pages. On some of our smaller, more specialized pages we have already selected a model that is appropriate to the needs of the other hardware available on that page.
