Computer Power Supply

Computer power supply units (PSUs) are pieces of hardware which convert mains electricity into usable DC power, for the components within your desktop computer. They convert AC (alternating current) from the mains to low-voltage, regulated DC (direct current).
You will find these power supplies in the back of a desktop computer. It is an internal hardware component.
Computer power supplies feature a power cable connector on one side and multiple wires on the other. These wires connect to various devices within the computer to supply power to them, for example motherboards and hard drives. Computer power supplies also have a fan which expels air out the back of a computer. They also prevent overheating through voltage control. There is usually a power switch at the back and another switch to alter the voltage.
