Questions tagged [power-supply]
A power supply is an electronic device that supplies electric power to another device, such as a computer, monitor or printer. This is achieved by converting wall power (or mains power) to a lower voltage, and in most cases also from AC to DC. Most power supplies also provide protection from overload, power surges and other potentially problematic or hazardous conditions.
