An ATX power supply provides a number of peripheral power connectors and (in modern systems) two connectors for the motherboard: an 8-pin (or 4+4-pin) auxiliary connector providing additional power to the CPU and a main 24-pin power supply connector, an extension of the original 20-pin version.

But the more frequent problem for motherboards is power surges. Most power supply units and motherboards adjust their voltages to accommodate small power surges. But if it’s a big one, it can fry your motherboard and all the components connected to it.

The 4-pin Fan power connector is found on motherboards within a computer case. This connector provides power to cooling fans and is typically used on the fan that cools the CPU.

The ATX 4-pin power supply connector is a standard motherboard power connector used to provide +12 VDC to the processor voltage regulator.

The power connectors for AT motherboards are two nearly identical 6-pin plugs and sockets. As designed by IBM, the connectors are mechanically keyed so that each can only be inserted in its correct position, but some clone manufacturers cut costs and used unkeyed (interchangeable) connectors.

This connector is used to supply additional 12V current to the motherboard. While the system will likely still run without it, higher current demands such as extreme overclocking or large video card current draws may require it. “

The switch is located on the back of the power supply next to the power cable. Short the two pins of the power connector using a pair of tweezers or needle-nose pliers . Remove the tweezers or needle-nose pliers as soon as the motherboard has been jumped.

How To Install A New Power Supply Mount the new power supply unit into the computer case by using the case mounting screws. Reconnect the internal wiring from the output of the power supply unit to the hardware components inside your computer case. Close up the computer case. Plug in the input cable to the power supply.

Q-Connector or ASUS Q-Connector, is an adapter, sometimes included with ASUS motherboards, which sits in between the motherboard front panel connectors and the front panel cables.

A motherboard power supply is the replaceable unit inside a computer that delivers power to the system. Also known as a power supply unit (PSU), it provides cabling that runs from the unit to the case’s power button, to the motherboard, drives, graphics card and fan(s).
