Collection: Power Supply

A power supply is an electrical device that offers electric power to an electrical load such as laptop computer, server, or other electronic devices. The main function of a power supply is to convert electric current from a source to the correct voltage, current, and frequency to power the load. It could be AC to DC or DC to DC. Consequently, power supplies are sometimes regarded as electric power converters. Some power supplies are standalone and separated from equipment to be external power supplies and others inside the device to be the internal power supplies.
