2022年8月11日 · In a personal computer (PC), the power supply is the metal box usually found in a corner of the case. The power supply is visible from the back of many systems because it contains the power-cord receptacle and the cooling fan. A typical PSU will have integrated connectors to send power to the motherboard, microprocessors, and SATA storage.

Simply put, a Power Supply Unit (PSU) is an electrical device that converts alternating current (AC) from the wall outlet into the direct current (DC) that your computer components require to operate. This conversion is vital, as most computer hardware—such as the motherboard, graphics cards, and storage devices—uses DC power.

A power supply unit (PSU) is a type of computer hardware that converts mains AC (alternating current) to low-voltage regulated DC (direct current) power for the internal components of a computer system.

2024年7月30日 · The PSU is the primary source of power for all the components in your PC. It converts the electricity from your wall outlet into a suitable form for various parts of your PC, providing different voltages and currents as required.

2024年8月28日 · There are three critical factors in choosing a PSU: Watts, Wires, and Width. Watts considers how much power the PSU can deliver, while Wires is about how many (and what type of) connections it offers. Width is about making sure that the PSU can fit into your case. Watts: How Much Power Do You Need?
