Does the computer motherboard need power supply?

php editor Banana is here to answer a common question: "Does the computer motherboard need a power supply?" The answer is yes. As the core of the entire computer system, the computer motherboard is responsible for connecting and controlling various hardware components. It must be connected to a power source for normal operation. The power supply provides power through the motherboard to other hardware so that they can work properly. Therefore, the computer motherboard is an indispensable part of the computer system, and it requires the support of a power supply to function.

Does the computer motherboard need power supply?

The computer motherboard requires power.

The main components of the motherboard that need to be connected to the power supply are:

The motherboard power supply.

CPU fan power supply.

Hard drive power supply.

Powered by independent graphics card.

Motherboard jumpers, etc.

How to connect external power supply to the motherboard?

First, we need to understand what a motherboard is. The motherboard is the most basic circuit board of the computer. It is the "motherboard" that connects all the electronic components in the computer, such as CPU, memory, graphics card, etc. The external power supply of the motherboard is to connect the power supply interface of the computer motherboard to the power interface of the power socket to provide power to the computer host.

Generally speaking, we need to use a power adapter (also called a power supply) to convert the power from the power socket into the voltage and current required by the motherboard.

Then, we connect the other end of the power adapter to the computer motherboard.

Finally, press the power switch to turn on the computer. Therefore, the external power supply of the motherboard needs to be connected to the power adapter and the computer motherboard and powered on before it can be used normally.

What kind of power supply does the computer motherboard come with?

1. ATX 24-pin (the old version of the power supply is 20-pin) plug, used to connect to the ATX socket of the computer motherboard. The 4PIN square plug (or 8PIN square plug) is used to provide independent power supply to the CPU.

2. Large D4PIN plug, for IDE hard disk and optical drive. Of course, some case fans also require a power plug.

3. The small 4PIN plug supplies power to the floppy drive. Today’s computers no longer use floppy drives.

4. SATA plug, for SATS hard disk and optical drive.

5. 6PIN plug (8PIN) plug, used for auxiliary power supply for independent graphics cards.
