The power supply unit or PSU as it can be known supplies power to a computer. Computers are plugged into an electrical outlet from which the power supply will then get the correct amount of electricity, which converts the AC current into a DC current. The unit will also monitor the voltage to avoid any spikes or surges, which is very common in modern electrical systems. Power supplies are measured by the number of watts its generates. The more powerful the computer is, the more watts it can give to the components.
