A high-quality PSU with sufficient clean power is essential for system stability, performance, and longevity. Inside every PC power supply is a complex array of circuitry designed to:. The PSU contains a voltage rectifier to convert AC into DC, along with other stages to filter, regulate, and split the DC power into the main voltage rails needed by computer components:. Modern PSUs use high-efficiency switched mode designs with tight voltage regulation. This minimizes power loss as heat while maintaining rock-solid, clean DC outputs free of ripple or fluctuation.
