Power supply unit


The power supply unit is the hardware component of a computer that provides electricity to the computer and other devices. A power supply unit also known as a switching mode power supply and power supply unit is usually used in a computer to change the voltage to the appropriate range for the computer A power supply unit converts the main AC to low-voltage regulated DC power for the internal components of a computer. You can see the power supply unit inside the computer. Inside the power supply unit, you can see a fan, component, and some cables.
