The PC power supply has been a standard of the junk box ... supplying an ever-expanding range of voltage rails at increasing power levels. There have been multiple different revisions of the ...

A computer power supply converts AC into multiple DC voltages. For example, 12 volts is commonly used for drives, while 3.3v and 5v are used by the chips and other motherboard components.

A well-known property of switching mode power supplies (SMPS) like those used in any modern computer is that they’re more efficient at higher AC input voltages. Power supply efficiency at ...

A power supply for electronic devices. Also called an "AC adapter" or "charger," power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages ...

Improving the window of usable power supplies for core voltages of devices helps ensure operation within the valid operating power-supply range. Different tolerances involved with power-supply ...
