<hardware> (PSU) An electronic module that converts high
voltage (110 or 240 VAC) alternating current mains
electricity into smoothed direct current at the various
differnt voltages required by the motherboard; internal
peripheral devices, cheifly storage devices: hard disks,
CD or DVD, floppy disks and external connections such as
USB. A PSU needs a high enough power output rating to
supply all the devices connected to it and should output as
little as possible electrical noise, both on the output wires
and as electromagnetic radiation.
See also uninterruptable power supply.
