Difference between EATX, ATX, Micro ATX, and Mini ITX Motherboards | Updated Guide in 2022

Micro ATX, Mini ITX, ATX, and EATX motherboards are all computer boards that house the essential components of a PC. They provide the foundation for your system’s performance and enable you to connect peripherals. But what’s the difference between them? Let’s take a closer look. 

Each motherboard form factor has its own advantages and disadvantages. Micro ATX motherboards are smaller than ATX motherboards, but they can still hold most of the components that you’ll need. They’re great for home theater PCs and small form factor builds. Mini ITX motherboards are even smaller and work best for ultra-compact builds. However, they don’t have as many expansion slots as larger motherboards do.

All types of Motherboard in 2022:

EATX: Extends ATX, supports more than eight expansion slots and up to four graphics cards, intended for high-end gaming PCs and workstations

ATX: The standard motherboard size since 1995, supports seven expansion slots and two graphics cards

MicroATX: A smaller alternative to ATX that’s commonly used in home theater PCs and budget gaming rigs

Mini-ITX: The smallest form factor available, these boards are popular in ultra-compact builds

Difference between EATX, ATX, Micro ATX, and Mini ITX Motherboards


The main difference between EATX and other motherboard form factors is size. EATX motherboards are the largest available and they offer the most expansion slots and support for multiple graphics cards. If you’re looking to build a high-end gaming PC or workstation, an EATX board is a good option.

Advantages and disadvantages of EATX motherboard:

– Advantages: More expansion slots and support for multiple graphics cards

– Disadvantages: Larger size can make installation more difficult


The ATX form factor has been the standard motherboard size since 1995. It offers seven expansion slots and support for two graphics cards. ATX boards are a good option for general-purpose builds, including gaming PCs.

Advantages and disadvantages of ATX motherboard:

– Advantages: Wide range of available boards and prices, good for general purpose builds

– Disadvantages: Some cases may be too small to fit an ATX board


MicroATX boards are smaller than ATX boards, but they still have enough room to accommodate most components. They’re a good option for home theater PCs and small form factor builds.

Advantages and disadvantages of MicroATX motherboard:

– Advantages: Smaller size can make installation easier, available in a wide range of prices and styles

– Disadvantages: Fewer expansion slots than ATX boards


If you’re looking to build an ultra-compact PC, a Mini-ITX board is your best bet. These boards are the smallest available and they typically have fewer expansion slots than larger boards. However, they’re more than enough for a basic gaming rig or HTPC.

Advantages and disadvantages of Mini-ATX motherboard:

– Advantages: Very small size can save space in your case, available in a wide range of prices and styles

– Disadvantages: Fewer expansion slots than ATX or MicroATX boards, may not support some high-end components

EATX, ATX, Micro ATX, and Mini ITX motherboards all have their own advantages and disadvantages. It’s important to choose the right form factor for your needs. If you’re not sure which one is right for you, consult with a professional or do some research online. With so many options available, you’re sure to find the perfect motherboard for your next build.

Why there are different types of motherboards?

A motherboard is the central printed circuit board in a computer. It acts as a ‘base’ to which all other components are attached.

The different types of motherboards available are designed to suit different needs and budgets. For example, a budget motherboard may have fewer features than a more expensive option, but it will still provide the basic function of allowing all the other components to communicate with each other.

Conversely, a high-end motherboard may offer a range of advanced features, such as support for multiple graphics cards or overclocking. Ultimately, the type of motherboard you choose will depend on your specific needs and budget.

Which type of motherboard is best for gaming?

When it comes to choosing a motherboard for gaming, there are a few things to keep in mind.

First, you’ll want to make sure that the motherboard is compatible with the type of CPU you’re using.

Second, you’ll want to choose a motherboard with plenty of slots for expansion cards.

Third, you’ll want to make sure that the motherboard has enough RAM slots to support your desired amount of memory.

Finally, you’ll want to consider the overall layout of the motherboard and choose one that will provide good airflow to keep your components cool.

With all of that in mind, there are a few different types of motherboards that are well-suited for gaming.

ATX motherboards offer good expandability and support for high-end CPUs, while microATX motherboards are a good option if you’re looking for a more compact size. If you’re looking for the best possible performance, however, you’ll want to opt for an E-ATX motherboard.

These boards offer the most expansion slots and support for the fastest CPUs and most powerful graphics cards. No matter which type of motherboard you choose, though, you’ll be able to enjoy a great gaming experience.

What is an advantage of the Mini-ITX?

Mini-ITX motherboards are one of the smallest motherboard form factors available. They’re perfect for small form factor (SFF) builds, HTPCs, and other space-constrained PC builds. Here are some of the primary advantages of Mini-ITX boards:

· Small footprint – Since they’re small in size, Mini-ITX motherboards have a smaller footprint than standard ATX or microATX motherboards. This can be helpful if you’re building a small form factor PC where every square inch counts.

· Low power consumption – A advantage of the smaller size is that Mini-ITX boards tend to use less power than their larger counterparts. If you’re looking to.

Final Verdict

Now that you know the difference between each motherboard form factor, you can decide which one is right for your needs. If you’re looking for a small and compact system, a Mini ITX motherboard might be the way to go. On the other hand, if you need a lot of expansion slots and room for multiple graphics cards, and EATX motherboard would be a better choice. Whatever you decide, make sure to pick the right motherboard for your specific needs.
