What are the different types of motherboard?

A motherboard (also called main board, system board, logic board or motherboard) is the core of a computer. It is the foundation on which all other components such as the CPU and RAM are connected.Most motherboards are manufactured in one of three sizes: ATX, microATX and mini-ITX. The size is determined by who manufactures it — there is no universal standard for motherboard sizing. Manufacturers may also refer to them as “full-size,” “medium,” or “small. ATX typically refers to boards that have a larger number of PCI slots, support for hard drives mounted on the bottom of the board, CPU sockets that accommodate at least two expansion cards, and a larger number of power supply connections.

A motherboard’s size is often described by its dimensions in inches. The most common sizes are ATX and microATX (12″ x 9.6″), although there are many other sizes. For example, E-ATX is used in high-end server computers and EEB is used for desktops. Gigabyte is the top brand as the the motherboards have top amd processor. Here is a list of different types of motherboard

1. ATX Motherboard

This type of best gigabyte motherboard  is the most common and popular motherboard used in computer systems around the world. It was originally designed for IBM computers and has become a de facto industry standard. This type of motherboard is available in full-size, micro-ATX and mini-ATX options. (12″ x 9.6″, 9.6″ x 9″, 6.7″ x 6.7″) ATX has the following features:

2. microATX

This motherboard size is the least commonly used of the ATX motherboards, because it was introduced to address the smaller form factor desktops, rather than expandability that ATX offered. It is available in full-size and mini-ATX forms.

3. mini-ITX

This motherboard size is becoming more common for manufacturers, since it has more expansion options for little space than an ITX motherboard would have.

It is limited in expansion option to a very small SODIMM memory slot and traditionally less than 1/3 of an inch in height.


Industry standards for these types of motherboards are minimal and many variations exist, with sizes ranging from smaller than mini-ITX to bigger than ATX. Most commonly, this motherboard type is used in servers and blades.

5. Mini-ATX 

This motherboard size was popular back when the Pentium 4 platform was dominant. It allowed builders to have a little more flexibility while trying to fit it into a small form factor desktop case.

6. microATX

This motherboard size was introduced to provide the ability to mount several expansion cards on a motherboard without requiring an ATX sized case or rack. It is approximately half the size of an ATX motherboard and is usually constructed with plastic or metal. It is also sometimes called mATX when contrasted with ATX (micro-ATX).

7. FlexATX 

This motherboard size was designed to allow cost-minimizing solutions while utilizing desktop cases, but not requiring that they be ATX sized. It is also sometimes called FLEX-ATX, miniITX or is simply the smallest of the popular ATX motherboard sizes. flexATX boards are approximately half the size of standard ATX motherboards and can easily be found in most office equipment such as printers and scanners (Dell for example).


The motherboard is a central component of the computer system. As such, it is often considered to be the “brain” of the system and is ultimately one of the most important parts. Manufacturers regularly update their offerings and sometimes offer new types for consumers to consider. Consumers should invest in a good quality motherboard that offers many features so that they do not have to upgrade in the future. You must purchase online gigabyte motherboard as they are cheaper.
