What are the interfaces of the power supply? What are the differences between power plugs?

The power interface on the motherboard is a socket on the motherboard, which is used to connect with the power supply plug of the switching power supply.

The schematic diagram of the power interface of the motherboard is as follows:

The longest one is connected to the motherboard, you look for it, there is only one port on the motherboard that can be perfectly connected with this interface; The first one on the left of the second row is connected to the computer peripherals for power supply, look down from the position closest to the power supply of the motherboard, lean to the left, and you can find it if you are careful; The middle one in the second row is connected to the SATA interface of the hard disk and optical drive, and the one on the right of the second row is connected to the IDE interface hard disk and optical drive, so these two are connected to the same device, but according to the different interfaces of the equipment, to decide which one to use, just look at the interface of the hard disk, to see which one can be plugged in.

The one with the most sockets is the PIN cable of the motherboard's power supply.

One of the flat ports on both sides is the power cable for the external device, and the other is the power cable for the hard disk.

The narrow socket of about 4cm is the hard disk data socket.

These 4 sockets are your original mouse, keyboard, and camera, and one is not your original one, which is a speaker or headphone.

Hard disks, optical drives, motherboards, and spare, the bottom one of the four in a row, because there should be 3 identical wires, each with a spare plug, plug in a fan or something.

This is plugged into the hard drive. I don't know how to ask again.

1. The use area is different.

European power supplies are mostly used in France, the Netherlands, Denmark, Finland, Norway, Poland, Hungary, Spain, Sweden and other European countries, as well as South Korea, Russia and other countries.

U.S. power supplies are mostly used in the United States, Canada, Brazil and other countries.

British standard power supply is mostly used in Hong Kong, the United Kingdom, India, Singapore, Malaysia, Vietnam, Indonesia and other countries and regions.

2. The characteristics are different.

The size of the British power plug is triangular, the surface is golden yellow, and it is made of copper material.

The European power plug is characterized by two round heads.

The characteristics of the American power supply are one round and two flat, and the plug specification is similar to that of the plug of the Chinese power supply, with two more holes in the plug of the Chinese power supply.

3. The voltage is different.

The voltage standard for the use of American power supply is 110V voltage for the front bucket; The voltage standard of European and British power supply is used as the base vertical voltage of 220V.
