This article mainly introduces which type of computer chassis is commonly used, which has a certain reference value. Interested friends can refer to it. I hope you will gain a lot after reading this article. Let's take a look at it.

The most commonly used computer chassis type is ATX, which supports most types of motherboards today. The chassis sold on the market are mainly ATX and Micro ATX chassis, while ATX chassis is much better than Micro ATX chassis in terms of heat dissipation and performance expansion, and ATX is still the mainstream of the market.

The chassis generally includes shell, bracket, various switches on the panel, indicator lights, and so on. The shell is made of steel plate and plastic, which has high hardness and mainly protects the internal components of the chassis. The bracket is mainly used to fix the motherboard, power supply and various drives.

As a part of computer accessories, the main role of chassis is to place and fix computer accessories, which plays a supporting and protective role. In addition, the computer chassis plays an important role in shielding electromagnetic radiation. Although it is not a very important configuration in DIY, the use of poor quality chassis is easy to short-circuit the motherboard and chassis, making the computer system very unstable.

There are many types of chassis. Now the market is more common is AT, ATX, Micro ATX and the latest BTX-AT chassis the full name should be BaBy AT, mainly used in the early machines that can only support the installation of AT motherboards. ATX chassis is currently the most common chassis, supporting the vast majority of motherboards. Micro ATX chassis is built on the basis of AT chassis, in order to further save desktop space, so it is smaller than ATX chassis. Each type of chassis can only install the type of motherboard it supports, which generally cannot be mixed, and the power supply is also different. Therefore, we must pay attention when choosing and buying.

The most commonly used computer chassis type is ATX, which supports most types of motherboards today.

The full name of ATX is AT Extended in English. Due to the non-standard of Baby AT motherboard market and the obsolete structure of AT motherboard, Intel issued a standard structure of PC in 1995-extended AT structure, that is, ATX motherboard standard, and the chassis derived under ATX specification is also called ATX chassis.

Compared with the Baby/Mini-AT structure, the layout of the ATX has made considerable changes: the Baby-AT adopts the horizontal structure of the chassis, and the Icano interface is located on the narrow side of the motherboard (24.4cm), while the ATX changes the chassis into a vertical structure, and uniformly transfers the Igamot O interface to the wide side (30.5cm) and makes it into the form of "backplane".

In addition, ATX also stipulates that the hot air of the CPU radiator must be discharged, which not only enhances the heat dissipation, but also reduces the dust accumulation in the chassis. Based on the ATX specification, several specifications such as ATX, Micro ATX, NLX, WTX, MiniATX and Flex-ATX are derived.

At present, the chassis sold in the market are mainly ATX and Micro ATX chassis. Micro ATX chassis is small in size and limited in scalability, so it is only suitable for users who do not require high computer performance, while ATX chassis is much better than Micro ATX chassis in terms of heat dissipation and performance expansion. ATX is still the mainstream of the market.

Thank you for reading this article carefully. I hope the article "which type of computer chassis is commonly used" shared by the editor will be helpful to everyone. At the same time, I also hope that you will support and pay attention to the industry information channel. More related knowledge is waiting for you to learn!
