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

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.
