What is an extended ATX motherboard?

A motherboard in a computer is like a skeleton in the human body, holding a long list of components together like a processor, graphics card, volatile memory sticks, hard drives, and more. It supervises the coordination between the computer’s components and the overall performance of a system. There are several board types in terms of different sizes and layouts or you may call those form factors. In short, if you want to get the most out of the system, you must know which type is perfect for you.

Those shapes differentiate various motherboard types like ATX, micro ATX, Mini-ITX, or extended ATX—all of these have different case types, power supply design, extensions slot, and numerous other factors. In this article, we will discuss what is an extended ATX motherboard and how it’s different from other motherboards that are mentioned above. In addition, we will look at its benefits, drawbacks, whether it’s suitable for tech enthusiasts or not, and many more.

What is an EATX motherboard?

To understand the extended ATX or EATX motherboard effectively, we have to know about the ATX motherboards. The ATX or Advanced Technology extended is the most common type of mother circuit in the market. It was introduced back in 1995 but many improvements have been done to it to make it perfect for current-era systems. In short, it’s a standard motherboard, and all other board types are slightly tweaked variants of this type.

The real question of what is an EATX motherboard is still there. Well, it’s an extended or bigger version of the standard ATX board with some benefits and a few drawbacks as well. The main differences between the both are related to the size, functionalities, and cost, obviously. I would like to discuss all the differences in detail and answer the question of whether we choose it or not. So, let’s get started.

Bigger size or form factor

The main and most obvious factor that makes various types of motherboards different is their size. That’s why we can see an extra word “extended” in the name of the EATX motherboard meaning bigger and more impactful. So, it has dimensions like 12 inches x 13 inches rather than the 12 inches x 9.6 inches in the normal ATX motherboard—the EATX boards are two to three inches extra in size.

These bigger boards are mostly made for servers or bigger computers where there is some extra space to accommodate these circuits. In contrast, in recent years the manufacturers have started offering these for systems that are used for high-end gaming or serious content creation. So, if you don’t run the servers businesses but want ultra-edge gaming performance, you can choose these boards.

Advantages: There are two main benefits of having an EATX motherboard. Firstly, there is a larger surface area that can help the mother circuit in dissipating the heat faster. Secondly, you can accommodate more elements like memory or graphics cards due to more sockets fitted on the board.

Disadvantages: Overall, the drawbacks of a bigger board are fewer than the advantages but still are. Since it has a larger size, you haven’t got many options for compatible PC cases. In addition, there is more risk of size-wise incompatibility for EATX than the smaller boards.  

More functionalities and useability

The EATX boards are bigger in size than all the other types of boards so they have more specifications, features, and many additional ports. For comparison, the ATX usually comes with 3-4 PCIe x16 ports and 4 RAM slots while having support to accommodate one graphics card. In contrast, the EATX usually has 4-6 PCIe x16 slots, 4-8 RAM sockets, and even can accommodate dual graphics cards.

As I mentioned earlier, the extended motherboards are made for high-end utility in gaming and content creation. All the specifications mentioned earlier are enough to prove the statement. So, if you want graphics performance during the intensive graphics-related workloads or want to accommodate more volatile memory than what ATX boards offer, these EATX motherboards are for you.

Price tag

Most of the time, the extended ATX motherboards are pricier than the ATX motherboards not because of their larger size but due to more performance, higher features, and more impressive specifications. In addition, you can find many of the EATX boards available at a lesser price than the normal ATX board. So the thing to remember is that an EATX board usually comes with more price than an ATX one only if you assure the same features level.

Conclusion

The extended ATX motherboard is two to three inches larger on one side than the ordinary ATX boards. There are some drawbacks of having this larger board but the number of benefits is higher. Due to a larger surface area, the rate of heat dissipation is fast and can maintain the cooling more effectively than a smaller size ATX board. But it causes more size-wise compatibility issues than normal ATX boards.

Many of the users were asking about what is an extended ATX motherboard and why we should buy this instead of others. It all depends upon your usage and requirements whether an EATX is better than others or not. If you’re a hardcore gamer and do some serious content creation, there is no better option than EATX in terms of performance. In contrast, if you have ordinary usage, an ATX board will work fine for you.
