Product Description:


Extreme Alpha is locked, loaded and ready to unleash the savage computing power of the groundbreaking 64-core AMD Ryzen Threadripper CPUs. Freshly equipped with 16 high-current 90A power stages our new goliath delivers supreme efficiency and enhanced headroom for overclocking, empowering you to push performance as never before. Maximized lane bandwidth lets you connect up to 33 devices simultaneously, while every single PCIe x16 and M.2 slot is wired with PCIe® 4.0 – so you're free to equip next-gen graphics cards or NVMe drives without fear of bottlenecks. Massive power, massive bandwidth.


• High-end desktop processors have greater power requirements due to the abundance of cores and memory channels. The latest Threadripper evolutions are particularly demanding, so intelligent VRM design and quality components are vital – especially for overclocked CPUs that live closer to the edge of stability. Accompanied with our critically-acclaimed UEFI and AI Suite tuning utility, ROG Zenith II Extreme Alpha offers an accessible range of manual tweaking tools, plus a highly-configurable auto-tuner that maximizes system control and performance with no expert knowledge required.

Teamed Power Architecture
• Modern CPU architectures up the ante for motherboard power design by transitioning from deep power-saving modes to full load almost instantaneously. Our latest VRM architecture rises to the challenge by utilizing teamed power stages to rapidly swing current, while maintaining exemplary thermal performance.

• Having the bandwidth to fuel multiple PCIe SSDs and graphics cards is part of the allure of high-end desktop platforms. ROG Zenith II Extreme Alpha fully exploits Threadripper's 64-lane capability, empowering you to connect up to 20 PCIe devices simultaneously. Every single PCIe x16 and M.2 is wired with PCIe 4.0, and the board also accelerates both wired and wireless networking – with both Aquantia 10 Gbps Ethernet and the latest Wi-Fi 6 (802.11ax) onboard.

• ROG Zenith II Extreme Alpha supports up to five M.2 drives for maxed-out storage. Two ride the ROG DIMM.2 module, next to the memory slots, and support drives up to 110m. There are another two slots under the aluminum heatsink cover, with a fifth one at the rear of the board. Every one of these slots is wired to support full PCIe 4.0 bandwidth, so they're compatible with the very latest NVMe SSDs – laying the foundation for the ultrafast transfer speeds needed to support machine-learning algorithms and drive higher-resolution game textures.

• AMD StoreMI is a software utility that accelerates any drive for better system responsiveness with reduced startup and software load times. It combines SSD performance with the affordability and capacity of an HDD by automatically moving frequently accessed data to dedicated SSD storage.

• Great power requires great cooling, so ROG Zenith II Extreme Alpha employs large VRM heatsinks that strike the right balance between surface area and mass. The chipset heatsink integrates an active-cooling solution, helping to keep the underlying silicon stay cool under pressure, and also employs the same airflow to chill the SoC VRM. The extra-large heatsinks also cover multiple M.2 slots, meaning Zenith II Extreme Alpha is fully armed to provide the best foundation for extreme PC systems – enabling higher performance at lower temperatures.

• Sound is an integral part of gaming immersion. ROG Zenith II Extreme Alpha's onboard audio joins the latest SupremeFX S1220 codec with a high-end ESS Sabre DAC. Power users in particular pipe content through multiple devices, so our Sonic Studio III software has an intuitive management interface that lets you route sound from applications to specific outputs. The board even supports DTS Sound Unbound technology, to create three-dimensional audio soundscapes that draw you further into virtual worlds.

• ROG is renowned for superior onboard audio, and ROG Zenith II Extreme Alpha is no exception. The front-panel headphone output features a SABRE9018Q2C integrated DAC/amp capable of reaching -108dB THD+N to provide playback that conveys all the subtlety and nuances of even the highest-quality audio track. The improved resolution derived from the ESS Hyperstream DAC architecture expands the soundstage to give a better sense of positioning. Beyond resolution, the 120dB DNR provides an extremely low noise-floor, further accentuating dynamics and punch. And, when you want to shift priority to musicality, our Sonic Studio software provides an array of EQ options, allowing the sound signature to be tweaked to suit your cans.

• In addition to extraordinary performance, ROG Zenith II Extreme Alpha provides extensive styling and customization options to let you build a system that truly stands apart.
