What Does a Motherboard Do?

A motherboard is the part that allows every piece of a computer to work together. It is like a big network that connects the main parts of computer such as the CPU, RAM, GPU, and storage devices. It sends signals and power between these parts so the computer can do its job. Without the motherboard, the computer parts would not know how to communicate or where to send information.

Types of Motherboard in Computer

There are different types of motherboard in computer that people use in computers. Each type has a special size and purpose. Some are big and full of features while others are small and simple. The type of motherboard a person chooses depends on what kind of computer they want to build. Whether it is a gaming computer or a small office computer the motherboard plays a big role in how everything works together.

1. ATX Motherboard

The ATX motherboard is the most common standard size. It measures about twelve inches by nine point six inches. This size allows for multiple expansion slots and ports. It supports full featured builds with powerful graphics cards. There are many ports for USB and audio on the rear panel. It is ideal for gaming rigs or workstations. An example is the ASUS ROG Strix Z790 E Gaming WiFi. This model offers robust power delivery for high end CPUs.

2. Micro ATX Motherboard

Micro ATX motherboards offer a balance between size and features. They are smaller than full ATX at nine point six inches square. This compact design fits in mid tower cases easily. There are fewer expansion slots compared to ATX but still enough for most users. It is suitable for budget builds or small office PCs. Power efficiency remains high in this form. An example is the MSI B550 Tomahawk. This board provides solid VRM cooling for AMD processors.

3. Mini ITX Motherboard

Mini ITX motherboards cater to space constrained setups. They measure six point seven inches by six point seven inches. This tiny size enables small form factor PCs like HTPCs. There is usually one PCIe slot for basic graphics needs. It is perfect for media centers or portable rigs. Cooling solutions must be chosen carefully due to limited space. An example is the Gigabyte Z790I Aorus Ultra. This version supports Intel’s latest chips in a mini package.

4. Extended ATX Motherboard

Extended ATX motherboards provide extra room for advanced configurations. They extend to twelve inches by thirteen inches or larger. This form allows more RAM slots and storage options. It is used in server builds or enthusiast overclocking setups. Compatibility with EEB cases is common here. There are enhanced I/O panels for professional use. An example is the Supermicro X13DAE. It handles dual Xeon processors for enterprise tasks.

5. EATX Motherboard

EATX stands for Extended ATX and shares similarities with the previous type. It typically sizes at twelve inches by ten point five inches. This variant focuses on enterprise level stability. There are redundant power connectors for reliability. It suits data centers or high availability systems. Expansion is maximized with multiple slots. An example is the ASRock Rack EPYCD8. This board excels in AMD EPYC based servers.

6. DTX Motherboard

DTX motherboards follow AMD’s compact standard. They measure nine point six inches by eight inches. This size is between Micro ATX and Mini ITX. It supports AMD chipsets with good airflow designs. There are provisions for discrete GPUs in small cases. It is great for silent home theater builds. An example is the rare ASUS M2N MX SE Plus. Modern equivalents are limited but functional.

7. Mini DTX Motherboard

Mini DTX shrinks further to eight inches by six point seven inches. It maintains compatibility with larger DTX cases if needed. This form targets ultra compact AMD systems. There is one PCIe slot for essential cards. It is used in embedded or kiosk applications. Power draw stays low overall. An example is the older AMD reference designs now phased out.

8. BTX Motherboard

BTX motherboards shift to a different layout for better cooling. They measure ten point five inches by twelve point eight inches in the standard version. This design improves airflow over CPU and GPU areas. It was aimed at reducing noise in systems. Adoption has been low compared to ATX. There are dedicated zones for heat pipes. An example is the abandoned Intel reference BTX board from mid 2000s.

9. Micro BTX Motherboard

Micro BTX reduces the size to ten point four inches by eight point three inches. It keeps the cooling advantages of BTX in a smaller footprint. This type fits mini tower cases well. There are fewer slots but efficient port layouts. It is suitable for quiet office desktops. Legacy support exists for older Intel platforms. An example is the Gateway OEM Micro BTX variants.

10. Pico BTX Motherboard

Pico BTX is the smallest in the BTX family at ten inches by eight inches. It focuses on barebones systems with integrated graphics. This form emphasizes low profile components. There is minimal expansion for basic computing. It works well in all in one designs. An example is niche industrial boards like those from AOpen.
