Power Supply

The power supply unit (PSU) is essential for converting AC electricity from the wall outlet into DC power for a computer's components. It distributes the correct voltage to the motherboard, CPU, and other peripherals. A high-quality PSU ensures system stability, efficiency, and protection against power surges, contributing to overall performance.
