A Power Supply Unit (PSU) is an essential component in electronic devices such as computers, data storage devices, and various computer accessories like USB adapters. Its primary function is to convert raw AC power from the main supply into usable DC power, which powers all the components within the device. PSUs come in different sizes, capacities, and efficiencies, tailored to meet the varying requirements of different devices. They play a critical role in ensuring stable and reliable performance while also contributing to energy efficiency and noise reduction.
