Power supply unit

A power supply unit (PSU) is a component inside a computer that converts the electricity from your wall outlet into the appropriate form and power levels needed by the computer’s internal parts. It ensures a steady and reliable flow of power to components like the CPU, graphics card, and motherboard. The PSU also provides protection against power surges and fluctuations. Without it, the other parts wouldn’t function properly or could be damaged. Think of it as the bridge that supplies the necessary energy for your computer to operate effectively.
