Dec 20, 2023 · Power Supply Units (PSUs), despite their name, transform power rather than providing it to systems. In particular, a power supply regulates the DC output voltage to the precise tolerances needed for contemporary computing components in addition to converting the alternating high voltage current (AC) into direct current (DC).
Jun 9, 2023 · PSU stands for Power Supply Unit, and it is the part of a PC responsible for converting the alternating current (AC) power from an electrical outlet into direct current (DC) power that...

A PSU distributes the converted power to various parts of your computer, including the motherboard, CPU, GPU, storage drives, and basically everything else. It ensures that each component gets the specific amount of power it needs to function correctly.
Nov 5, 2024 · A power supply unit (PSU) is a hardware device that converts AC electricity into DC electricity and then distributes it to the rest of the computer. On a standard desktop computer, the PSU is where the power cord plugs into and usually has an I/O power switch on it.
A power supply unit (PSU) converts mains AC to low-voltage regulated DC power for the internal components of a desktop computer. Modern personal computers universally use switched-mode power supplies. Some power supplies have a manual switch for selecting input voltage, while others automatically adapt to the main voltage.
A Power Supply Unit (PSU) is a critical hardware component that provides electrical power to a computer or other electronic device. It converts AC power from a wall outlet into DC power that can be safely used by the computer's internal components.
