The Gigabyte X570 Aorus Extreme is a top choice for PC enthusiasts looking for motherboards with Ryzen processors.

While the EATX motherboard space seems to be dominated by Intel processors, it is still possible to find a board that supports the Ryzen architecture. Although Ryzen CPUs have typically been marketed toward budget gamers and lower-cost builds, you can still enjoy all of the benefits of the EATX form factor without having to ditch your Ryzen processor.

This motherboard immediately steals the show in any build with its jet-black finish and vibrant RGB LEDs. With the Aorus logo emblazoned across the I/O shield, you get a sense of high-quality and class typical of any EATX motherboard. With a “Fins-Array” heatsink, direct touch heat pipes, and “NanoCarbon” Baseplate, this motherboard is built from the ground up with durability.

The X570 chipset ensures overclocking compatibility, and the Zen 3 architecture supports some of the most powerful AMD Ryzen processors. The only noticeable disadvantage to this board is the lack of DDR5 support. As AMD-based motherboards typically lag behind Intel-based motherboards, this is no surprise. However, you’ll be pleasantly surprised that you can install a maximum of up to 1TB of RAM. You’ll often only see RAM limits this high on server-grade motherboards, so seeing such a tremendous limit on a consumer motherboard is rare.

The price is very reasonable for an EATX motherboard as well. Though not the cheapest option on our list, it is a close second, with an MSRP of under $700. While still a pretty penny to pay for a motherboard, this board is a great option if you want to upgrade to the EATX form factor without spending a fortune.

The Asus Pro WS WRX80E Sage is a performance-oriented motherboard for those who want to use their PC for far more than gaming.

A powerful CPU deserves an equally capable motherboard with an AMD Threadripper platform. With up to 128 cores per processor, AMD Threadripper CPUs are ideal for the performance enthusiast looking to push the limits of what is possible.

This motherboard doesn’t try to wow you with flashy lights and shiny logos. Instead, it gets straight to the point with an all-black finish and plain design. Looking closely, you’ll see every square inch of this motherboard’s space is utilized. You can build a graphics processing powerhouse with seven full-size PCI-e 4.0 slots. You can also use these slots for installing a RAID array of solid-state drives for jaw-dropping data transfer speeds.

Additionally, you get eight RAM slots for installing up to 2TB of 8-channel DDR4 “error-correcting” RAM, something you will typically only find on servers costing many thousands of dollars. With this level of RAM expansion, you can almost forget that it does not support DDR5. This is because the error correction provided offers you enhanced performance and fault tolerance.

As you might expect, this motherboard is right in line with typical EATX motherboard pricing. While you will undoubtedly spend more on an AMD Threadripper processor, this motherboard offers you many features, performance, and expansion capability for the price.

How To Pick The Best EATX Motherboard: Step by Step

EATX leads the pack when it comes to innovation among motherboards. You’ll often see EATX motherboards sporting additional features not present on smaller form factors. However, picking out the best motherboard can be challenging with confusing terminology.

Overall, there are four specific aspects you should pay attention to when researching the best motherboard for your needs:

  • Features
  • Expansion
  • CPU Compatibility
  • Price and Value

Features Offered

If you’re set on using an EATX motherboard, you’ll enjoy features that are most lacking in smaller motherboards. The additional size allows manufacturers to load motherboards with enhanced features like automated water cooling, AI networking, and complex thermal management. 

While USB 3.2, USB Type-C, and Gigabit ethernet are common, EATX models take these features to the next level. If you’re building a PC with future-proofing in mind, you’ll want to look out for a few specific features.

Most EATX motherboards will offer premium options like 10GBe LAN connections, built-in WiFi 6, and Bluetooth. Along with these features, you’ll often see extended safeguards like overclocking protection, reinforced slots, and thick PCBs. Carefully consider the feature set on each motherboard you’re considering to ensure it will meet your demands.

Expansion Options

EATX motherboards are substantially larger than other form factors and have more room for expansion. While smaller boards are limited in terms of PCI-e slots, RAM slots, and SATA connections, EATX motherboards offer even further options for upgrades. 

Want to expand your storage? You’ll need a motherboard with as many SATA and M.2 ports to connect multiple hard drives and storage devices. If you’d like to build a multitasking powerhouse, the extra space for RAM will allow you to expand your PC’s memory capacity.

While DDR5 compatibility will ensure you have support for the next generation of RAM, you should also focus on the maximum capacity supported by your board. Fortunately, EATX motherboards enjoy higher capacity limits, often topping out at 128GB of RAM or more.

Certain motherboards also cater to customization enthusiasts. If you want the freedom to build custom liquid-cooling loops and extensive RGB setups, specially designed EATX motherboards are ideal.

CPU Compatibility

The question of Intel vs. AMD has raged on for many years. If you are an AMD enthusiast, you should look for Ryzen motherboards that support Ryzen or AMD Threadripper processors. For AMD support, you’ll need an AM4 socket motherboard. Although AMD-based EATX motherboards are uncommon, it is still possible to find models that offer the features and expansion capabilities you need.

Intel-friendly motherboards are extremely common in the EATX form factor. Most PC enthusiasts gravitate towards Intel CPUs due to their historically higher benchmarks and performance ratings. Because of this, you’ll often see many more EATX motherboards for Intel CPUs. If you’re hoping to join the Intel crowd, you’ll need to look for an LGA 1200 or 1700 socket type.

Price and Value

Price is often a pain point when it comes to EATX motherboards. Due to the enhanced feature set and build quality of EATX boards, they tend to come with higher price tags. Since EATX motherboards are so expensive, you’ll want to ensure you get the latest technology and cutting-edge features. 

Sinking money into an older EATX motherboard can be a bad move, as your upgrade path will be limited. However, if you’re on a budget, you can often find a good deal on an AM4 EATX motherboard instead of Intel-based boards.

What To Know Before Buying an EATX Motherboard

Before you buy an EATX motherboard, you should familiarize yourself with the options available. With so many choices, it’s easy to get overwhelmed and pick the wrong one. It doesn’t help that many motherboard manufacturers use confusing terminology. 

For starters, ensure your PC case has enough space to fit your EATX motherboard. Remember, EATX motherboards are slightly larger than traditional ATX motherboards. So, make sure your case is EATX-compatible and has the proper screw mounts and connections.

Additionally, you’ll need to know what type of RAM and CPU to use with your motherboard. Fortunately, motherboards are identified by their socket type. Simply match your CPU’s socket type with your motherboard’s socket, and you’ll ensure compatibility. GPU compatibility is another concern. You must verify that your motherboard offers PCI-e 4.0 support to run the latest graphics cards.

Using an EATX Motherboard: What it’s Like

EATX motherboards offer greater freedom than smaller form factors, plus extra capabilities. However, you’ll need a larger PC case. Motherboard installation is similar to every other motherboard but on a larger scale. To maximize your motherboard’s potential, you should invest in higher quality RAM, storage devices, and peripherals. The enhanced overclocking and BIOS settings included with EATX motherboards make customizing and tweaking your settings fun.
