Computer Power Supplies

Computer power supplies, commonly referred to as PSUs (Power Supply Units), are essential components that provide electrical power to all hardware inside a desktop computer. A power supply converts electricity from a wall outlet into regulated voltages that can safely power components such as the motherboard, processor, graphics card, storage drives, and cooling systems.

Inside a desktop PC, the power supply distributes power through various cables and connectors designed for different hardware components. These include connectors for the motherboard, CPU power, graphics cards, SATA storage devices, and other peripherals. Without a reliable power supply, the computer cannot operate or maintain stable performance.
