What is the main function of a computer power supply unit?

Answer and explanation

Correct answer: Converting electrical power into voltages suitable for components

The power supply unit, or PSU, receives electrical power from the mains and converts it into regulated voltage levels needed by the motherboard, processor, storage devices, and other components. Therefore, option A is correct. File compression belongs to software, writing processor instructions is a programming task, and creating passwords is an operating-system or user-security function, not a PSU function.
