power supply

   Also found in: Acronyms, Wikipedia 0.04 sec.

An electrical system that converts AC current from the wall outlet into the DC currents required by the computer circuitry. A computer power supply typically generates multiple voltages. For example, 12 volts is used for drives, and either 3.3 or 5 volts is used for the electronic circuitry. See power adapter.
