Where to buy used power supplies? What brands of power supplies are you selling? What are the power supply components?
Power supplies or PSU (Power supply units.) are commonly used to power on Desktops. It works by turning AC into DC power. That DC power is then used to power on your CPU which then powers on the motherboard, driving power to all the other major peripheral components such as hard drive, CPU fan, ram, and other components. Common power supply units are rated by WATT input, and output. Most motherboards require a specific wattage to power it on. If the wattage is not strong enough to power on the motherboard then your PC wont power on. Common power supply brands are Delta electronics, Newton, Bestec, EVGA, Thermaltake, and Corsair.
