EATX vs ATX: Which is Better for Gaming?

When deciding on the ideal motherboard for your gaming PC, the decision boils down to your specific needs. If you’re operating on a tight budget and your goal is a high-end gaming PC that requires only one graphics card, then the ATX motherboard is your best bet. It is designed to meet the requirements of most standard gaming rigs.

On the other hand, if you’re aiming to construct a top-tier gaming PC equipped with multiple graphics cards, the EATX motherboard stands out. Also known as Extended ATX, this motherboard offers more space, allowing for a greater number of components, making it a favorite among enthusiasts and professional gamers.

Size and Compatibility Considerations

One of the most prominent differences between the two types of motherboards is their size. EATX motherboards, or Extended ATX, measure 12 x 13 inches, adding an extra 3.4 inches to one side. This additional width provides more room for installing components, especially if you’re planning on a multi-GPU setup.

Compatibility is another crucial aspect to consider. While an ATX motherboard can easily fit into an EATX case due to identical mounting patterns, the reverse isn’t always true. The larger EATX motherboard might not fit comfortably into an ATX case, leading to potential installation challenges.

Another benefit that comes with the larger size of the EATX motherboard and its corresponding case is enhanced airflow. With more space inside, there’s better ventilation, ensuring that the components remain cool during intense gaming sessions.


What is the precise size of an EATX motherboard?

The EATX (Extended ATX) motherboard has dimensions of 12 × 13 in (305 × 330 mm).

Is airflow better in an EATX case compared to an ATX case?

Yes, with the bigger size of an EATX case, there tends to be more airflow, which can be beneficial for cooling components, especially during extended gaming sessions.

Can I use an EATX motherboard for non-gaming purposes?

Absolutely! While EATX motherboards are popular among gamers due to their ability to accommodate multiple graphics cards, they can be used for any high-performance computing needs, including video editing, 3D rendering, and more.


In conclusion, both EATX and ATX motherboards have their unique advantages and are tailored to cater to different needs. While the EATX is designed for those who seek the pinnacle of gaming performance with multiple graphics cards, the ATX serves those who want a high-quality gaming experience without breaking the bank. It’s essential to evaluate your specific requirements, budget, and future expansion plans before settling on one. No matter the choice, both motherboards promise a compelling and immersive gaming experience.
