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. Good voltage regulation is essential for proper operation and stability. PSUs contain many components that slowly degrade over time.
