Computer Power Supply

A computer ATX power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of the computer. The ATX (Advanced Technology eXtended) switched-mode power supply is turned on and off by a signal from the motherboard.

PSUs can be damaged by power surges, corrosion or overheating. Fortunately, they are easy to replace and are fairly cheap, considering that they drive the whole computer. A 400W ATX PSU costs only R199 and a 300W ATX PSU only R150.
