Product Overview

ASUS ROG Zenith II Extreme is a high-end motherboard based on AMD's TRX40 chipset and designed for 3rd-gen Ryzen Threadripper processors. ASUS also markets a more extreme version of this motherboard, the ROG Zenith II Extreme Alpha, that features upgrades in the VRM section with 16 phase 90A power stages (in place of the 70A ones in the standard board).
As the Threadripper offers considerably more PCIe 4 lanes as well as quad-channel DDR4 memory, the Zenith II Extreme adopts the Extended ATX (E-ATX) form factor. It allows the user to use up to 256GB of memory, ECC or otherwise, and 3-way multi-GPU setup (SLI or CrossFire).
To drive the Threadripper processor, the Zenith II Extreme comes with 16 Infineon TDA21490 power stages as well as other premium electronic components.
The ROG Zenith II Extreme also comes with a color OLED display with extensive Aura Sync RGB lighting. There are even two additional RGB headers and two addressable headers for more customizability in custom builds.
For productivity tasks, the Zenith II Extreme comes with both Gigabit ethernet and a 10Gbps LAN connection. Naturally, WiFi 6 and Bluetooth 5.0 are available, too. Last but not least, this premium motherboard also features an ESS Sabre DAC.
ASUS also markets another TRX40 motherboard in the ATX form factor, the ROG Strix TRX40.
