5 Different types of motherboard and their functions

Last Updated on January 13, 2023 by Circular Guru

Do you know what are the Different types of motherboard and their functions? 5 most common types of motherboards are:

  • 1. ATX motherboard
  • 2. LPX motherboard
  • 3. BTX motherboard
  • 4. MICRO-ATX motherboard
  • 5. MINI-ITX motherboard

An integral part of any computer is its motherboard. The CPU, memory, and expansion slots, among other system necessities, are all housed within. The motherboard also provides connectors for attaching other devices, such as hard drives, optical drives, and video cards.

Motherboards come in a variety of shapes and sizes, but they all have a few things in common. They typically have a number of screw holes on the back so they can be mounted in a case, and they usually have a number of connectors on the edge that allow you to plug in various cables. On most motherboards, these connectors are color-coded so you can easily identify them.

The motherboard’s chipset is the central component. The chipset determines what kind of processors and memory your computer can use, as well as the type of ports it has. So, today in this article, let’s look at what exactly a motherboard is, its uses, how it works,s and the different types of motherboards available today!

What Exactly is a Motherboard?

As the central processing unit (CPU) of a computer or other electronic device, the motherboard is the most important printed circuit board. It houses the system’s brains, including the central processing unit (CPU), memory, and I/O ports. Motherboards are typically rectangular, and they come in a variety of sizes and shapes.

The motherboard is one of the most important parts of a computer. It’s responsible for holding together all of the different components, and it also provides a platform for connecting them to each other. The CPU, memory, and other critical components are all mounted on or around the motherboard.

Motherboards also provide a number of important functions that help keep your computer running smoothly. They act as a central hub for communication between the different parts of your system, and they also manage power distribution to ensure that all of your hardware is getting the appropriate amount of electricity.

How Does a Motherboard Work?

The motherboard contains the CPU, memory, chipset, PCI slots, and SATA connectors. It also has a built-in graphics adapter and audio controller.

The motherboard works by allowing different components to communicate with each other. The CPU communicates with the memory, chipset, and PCI slots. The chipset communicates with the SATA connectors and the built-in graphics adapter. The audio controller communicates with the audio ports on the front of the computer case.

Functions of a Motherboard

A computer’s motherboard is its central processing unit. It contains the central processing unit (CPU), memory, and other key components. The motherboard’s main function is to provide a platform for these components to work together.

The motherboard also controls how data moves between the different parts of the computer. It does this by using a set of buses that run between the different components. These buses can be thought of as roads that data travels down. The motherboard decides which bus each component uses, and how much bandwidth each one gets.

Finally, the motherboard provides power to all of the components on it. This power comes from either the power supply or from batteries in laptops.

Different Types of Motherboards

Mainly, there are three different types (form factors) of motherboards available today. These are ATX, Micro-ATX, and the Mini-ITX. Let’s learn more about these motherboard types in greater detail!

1. ATX

An ATX motherboard is a type of motherboard that is widely used in desktop computers. It has a number of key features that make it popular, including its compact size, its ability to support multiple processors, and its wide range of ports and connectors.

ATX motherboards come in two main sizes: the full-sized ATX board, which is about 12 inches by 9.6 inches, and the smaller Micro-ATX board, which is about 9.6 inches by 9.6 inches. The ATX form factor was originally designed in 1995 by Intel, and it has been widely adopted since then.

One of the most important features of an ATX motherboard is its ability to support multiple processors. Many newer boards include support for both AMD and Intel processors, making them compatible with a wide range of systems.

2. LPX

LPX motherboards were designed as a low-profile alternative to the ATX motherboard form factor. LPX motherboards are about 1/4 the size of an ATX motherboard and usually use a riser card to allow for additional PCI or AGP slots. LPX motherboards are popular in small form factor cases.

3. BTX

The BPX motherboard is the latest in motherboards from Gigabyte. It is designed with the business user in mind and boasts features that are perfect for corporate settings. Some of these features include dual Intel Xeon processors, SAS 12Gb/s support, and Thunderbolt 3 connectivity.

The board also has a number of other impressive specs, including a total of 10 USB ports, 11 SATA connectors, and room for up to 128GB of RAM. This makes it an ideal choice for users who need a powerful and versatile motherboard that can handle a variety of tasks.

4. Micro-ATX

A micro-ATX motherboard is a type of motherboard that is smaller than the traditional ATX motherboard. This type of motherboard is often used in small form factor computers and can be found in both desktop and laptop computers. The micro-ATX motherboard measures 9.6 inches by 9.6 inches, which is significantly smaller than the 12-inch by 9.6-inch size of the ATX motherboard.

The micro-ATX motherboard has a variety of different connectors, including a 24-pin power connector, four SATA connectors, and two PCI Express x16 slots. The micro-ATX motherboard also has a single CPU socket and four memory slots. Because of its smaller size, the micro-ATX motherboard does not have as many expansion slots as the ATX motherboard.

5. Mini-ITX

A Mini-ITX Motherboard is a motherboard that is specifically designed for use in mini-PCs and small form factor systems. They are typically smaller than standard ATX motherboards and offer fewer features and ports. However, they still provide all the basic functionality you need to build a functional PC.

There are several reasons why you might want to use a mini-ITX motherboard in your system. Perhaps you need a small form factor system for space-constrained applications. Or maybe you want to build a compact media center or home theatre PC. Whatever the reason, mini-ITX motherboards provide an efficient and cost-effective way to build a small PC.

How long does a motherboard last


In conclusion, there are many different types of motherboards and their functions vary from product to product. It is important to know the functions of each type in order to make an informed purchase.

Be sure to ask questions and do your research before buying a motherboard to ensure that you are getting the right one for your needs. Thank you for reading!
