Let s take a look at the computer motherboard.

A computer chassis motherboard, also known as a mainboard, systemboard, or motherboard.

It is divided into two types: commercial motherboards and industrial motherboards. It is installed in the chassis and is one of the most basic and important components of the microcomputer. Motherboards are generally rectangular circuit boards on which the main circuit systems that make up a computer are mounted.

Generally, there are BIOS chips, IO control chips, key and panel control switch interfaces, indicator plugs, expansion slots, DC power supply connectors for motherboards and plug-in cards, and other components.

The motherboard has an open architecture. Most motherboards have 6-15 expansion slots for PC peripherals to plug in control cards (adapters). By replacing these plug-in cards, the corresponding subsystems of the microcomputer can be partially upgraded, so that manufacturers and users have greater flexibility in configuring models.

：1.First-line brands (in no particular order).

Msi. Asus.

Gigabyte. 2.Second-tier brands (in no particular order).

Elite. Ascension.

Yingtai. Weconex.

Spartacus. Javi.

Pan Ying. Top Star.

3.Third-tier brands (in no particular order).

ASRock. Regards.

Yingtai. Cordia.

Walk aimlessly. Jingwei.

4.OEM products, most of the motherboards at this level are channel providers, there is no manufacturing capacity, and they are completely OEM by other manufacturers, so I call them incompetent brands.

Onda. Rainbow.

Mingxuan. Double sensitive.

Metier. Synnex.

Dantin. 5.Needless to say, miscellaneous cards, **low, poor quality, repair rate*** best don't buy:

Jetwave. Branch Brain.

Vibot. Heavenly Machine.

Same crown. Jixiang.

Atillon. Ailinsa.

Wuliangye. God Six.

Msi. Asus.

Gigabyte. Rainbow.

Yingtai. Onda.

Metier. Jetwave.

Spartacus. Pan Zheng ** hand.

1. Regardless of the difference between the size and size of the board, only from the perspective of workmanship materials and expansion, Z390M Mortar is better.

2. There is a DP** output port on the Z390M Mortar backplane, an optical audio output port, and one more heat sink in the CPU power supply part of the motherboard, but there are 2 less SATA interfaces.

Of course, the first motherboard with plus in front is better, this one is a large board, and the back one is a small board, because the large board has more space, the wiring is more reasonable, the electrical stability is higher, and the scalability is also better than the small version.

The band m is a small plate.

It's enough to use a mortar, the scalability is better, and there is no need to buy an ITX motherboard without installing an ITX host.

What is the role of a motherboardWhat is a computer motherboard? What does a motherboard do? Motherboard, also known as mainboard, systemboard or motherboard; It is installed in the chassis and is one of the most basic and important components of the microcomputer.

Next, let's step into the world of motherboards.
