PSU is an acronym that stands for Power Supply Unit. It refers to a hardware component in electronic devices that provides electrical power to the other parts of the device.
A PSU is an essential component in computers, gaming consoles, televisions, and other electronic appliances. It converts the alternating current (AC) from a power outlet, typically at high voltage and frequency, into a direct current (DC) at lower voltage levels that the device's components can use. The main purpose of a PSU is to supply stable and consistent power to the various components, ensuring their proper functioning and protection against fluctuations or surges.
PSUs come in various types, such as ATX (Advanced Technology Extended) PSUs commonly used in desktop computers, as well as SFX (Small Form Factor) and TFX (Thin Form Factor) PSUs used in smaller devices or compact systems. They are often rated with a maximum power output capacity, measured in watts, indicating the amount of power they can deliver.
In addition to providing power, PSUs often include safety features like overload protection, overvoltage protection, and short-circuit protection. They also include several connectors and cables to distribute power to the different components in a device, including the motherboard, storage drives, graphics cards, and peripherals.
Overall, the PSU is a crucial component in electronic devices, ensuring the reliable and efficient distribution of power for the proper operation and longevity of other components.
