AMD TRX40 Chipset
The AMD TRX40 chipset delivers overclocking capabilities for the the AMD Socket sTRX40 3rd Gen Ryzen Threadripper series processors, which can boast up to 64 cores. It provides PCIe 4.0 support, USB 3.2 Gen 2 10 Gb/s ports, and eight SATA 6 Gb/s ports for faster data retrieval.
Connectivity
To build a powerful gaming computer, you'll need to have to bandwidth to fuel multiple PCIe SSDs and graphics cards. Thanks to Threadripper's 64-lane capability, this motherboard can connect up to 20 PCIe devices simultaneously. Every single PCIe x16 and M.2 is wired with PCIe 4.0, and the motherboard also accelerates both wired and wirelessly networking, with both Aquantia 10 Gb/s Ethernet and Wi-Fi 6 (802.11ax).
Cooling
Keeping your system cooled is essential when it comes to running a powerful system. This motherboard utilizes large VRM heatsinks that balances surface area and mass. The chipset heatsink integrates an active-cooling solution and employs the same airflow to chill the SoC VRM. The extra-large heatsinks also cover multiple M.2 slots. There's also support for both air cooling and liquid cooling via the appropriate headers.
Audio
Audio is important for an immersive gaming experience. This motherboard utilizes the SupremeFX S1220 codec with a high-end ESS Sabre DAC. Use the Sonic Studio III software and its intuitive management interface to route sound from applications to specific outputs. This motherboard also supports DTS Sound Unbound technology, allowing you to create 3D audio soundscapes.
ASUS Aura Sync
Sync up with ROG components, from graphics cards and monitors to mice and keyboards. Aura Sync lets you customize the RGB lighting of all your Aura Sync compatible devices for a uniformed look.

Is this board ATX or EATX?
Asked by: MokyNZ
This is an E-ATX motherboard with a dimension of 310mm x 277mm. A standard ATX motherboard usually has the dimensions 305mm x 244mm. E-ATX is not a standard dimension usually. It has the length roughly the same as a standard ATX, whereas the width can vary from motherboard to motherboard. As you can see, not a huge difference (5mm) in the length, but the width is more by 33mm.
