About the difference between computer motherboard ATX and ITX
At present, the choice of office business computers is nothing more than assembling desktop computers and portable notebook computers.
The chassis for assembling a desktop computer is relatively large and powerful. It can be connected to an external GPU discrete graphics card. It has a rich interface and a variety of versions of cards. It is a favorite of many players.
Portable notebook computers are relatively low power consumption, compact and mini, compact and do not occupy space, and are easy to carry. They are one of the preferred computers for people who travel frequently.
Since most notebook computers are integrated by manufacturers, it is relatively difficult for customers to add modules. For commercial or home customers, the computers they require do not have to be moved frequently. In the case of assembled desktop computers with the same configuration, the price is relatively low and can be integrated. The advantage of high degree is the first choice for commercial or home use.
Desktop computers are composed of motherboards, CPUs, memory, hard drives, power supplies, and chassis. The choice of the motherboard largely determines the configuration trend of the entire computer. At present, the main boards are divided into the following categories according to their size:
Big board: ATX, Mini ATX, XL-ATX, non-standard E-ATX;
Small boards: MATX, μATX, FlexATX;
Mini board: ITX (including Thin-ITX);
Large board: standard E-ATX, EE-ATX, HPTX, WTX.
For the size of the above motherboard:
Different motherboards differ mainly in layout size, configuration functions, and scope of application. In terms of plate size, ITX is 170mm*170mm, M-ATX is 244 mm*244 mm, ATX is 305mm*244mm, E-ATX is 305mm*330mm;
In terms of configuration function, according to the percentage of use, many customers choose ATX or ITX motherboards when assembling computers. ITX has fewer functions than ATX; in terms of scope of application, ITX is a mini host and ATX is a mainstream host. The following are specific instructions:
1. ATX is the current mainstream installed version, with a size of 305mm*244mm, mid-to-high-end positioning, and can meet the needs of mainstream users in terms of the type, number of expansion slots and power supply specifications. It is better in terms of scalability and heat dissipation. Generally, it will be equipped with three PCI-E slots, support 4 dual-channel memory, and support two sets of M.2 slots.
2. The ITX version is a version that is mostly chosen by niche players or mini-host users. The size of the version is 170mm*170mm. The positioning needs to be judged according to the brand and series (high and low), and the type, quantity and number of expansion slots The power supply specifications are relatively streamlined compared to ATX.
