In the context of computer components, what does PSU stand for?

The acronym PSU stands for Power Supply Unit. This component is critical in a computer system as it is responsible for supplying electrical power to various components within the computer. The PSU converts the alternating current (AC) from the wall outlet into the direct current (DC) that the computer's components, such as the motherboard, processor, and hard drives, require to operate.

A typical PSU includes several connectors and cables that deliver power to the various parts of the system, and it often features different voltage outputs to accommodate components that operate at different power levels. The efficiency and capacity of the PSU are important for system performance and stability, as well as for ensuring that the power needs of all components are met without overloading the system.

The other options presented, while potentially relevant to computer terminology, do not accurately define what PSU stands for in the context of computer components. This specificity is essential for understanding and communicating effectively about computer hardware.
