PS

Short for Power Supply and sometimes abbreviated as PSU, which is short for Power Supply Unit. The PS is an internal hardware component used to supply the components within the computer with power. Besides properly supplying power to the computer and all its internal components, the power supply also converts the AC electrical current found in most standard wall sockets throughout the United States into a lower DC voltage that the computer components use. The image to the right is of an Antec True 330, 330 Watt power supply to help illustrate what a power supply looks like.
