The unsung and often forgotten hero of any PC build, the power supply is crucial to ensure your computer functions properly. Just like its name suggests, the purpose of a power supply unit (PSU) is to supply power to all of your PC components. Like CPUs and hard drives, power supplies come with many different features.
What does PSU in computer do?
Despite the name, Power Supply Units (PSU) do not supply systems with power – instead they convert it. Specifically, a power supply converts the alternating high voltage current (AC) into direct current (DC), and they also regulate the DC output voltage to the fine tolerances required for modern computing components.
