PSU |
PSU (Power Supply Unit) is the component that provides power for a computer to function. The power cord from a standard electrical outlet connects to the PSU, which converts the AC current to DC and regulates voltages that the separate devices in the computer need to function. The PSU usually has a wattage rating, which indicates the maximum power output of the PSU under load. Faster computers with more components require more powerful (in terms of watts) power supplies to provide adequate power to all components. |
