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.
We became the first manufacturer to implement phase-doublers when we shipped our A8N32-SLI Deluxe motherboard, back in 2005. The board’s VRM was lauded for elegantly overcoming the power handling capabilities of components that were available at the time and also reducing voltage ripple. Those benefits led to phase-doublers becoming universally accepted in the industry, and they are still used for similar purposes today.
However, the current crop of CPUs pack more cores than their predecessors, and the latest instruction sets allow them to crunch computationally-dense workloads at an incredible pace. As an added bonus, they also consume less power at idle and can transition between loads states much more quickly. These improvements necessitate a re-evaluation of power-design priorities because phase-doublers add a propagation delay that hampers transient response.
While doublers help extend the number of effective phases, they do so at the cost of a processing delay.
Fortunately, the latest integrated power components can handle higher currents than the devices of yesteryear, making it possible to implement a simple circuit topology that isn’t hamstrung by the processing lag of phase-doublers. That’s why ROG Zenith II Extreme utilizes teamed power stages to deliver higher burst current per phase, while maintaining the thermal performance of phase-doubled designs.
The teamed architecture allows two power stages to work in tandem to provide more power to the CPU.
Each VRM component serves a specific purpose. PWM controllers and phase-doublers control the circuit, and the power stages do the heavy lifting from an electrical and thermal standpoint. That’s why ROG Zenith II Extreme utilizes 16 Infineon TDA21472 power stages. The TDA21472 sits at the top of Infineon’s lineup and features a low RDSON to reduce switching and conduction losses, helping to improve overall thermal headroom.
The MOSFETs within the power stages generate the most heat as they are responsible for voltage conversion and delivery to the CPU from the 12V EPS connector.
Infused with proprietary memory trace layout tweaks that improve signal integrity and mitigate noise, OptiMem III allows memory kits to run at lower latencies and reduced voltages while operating at higher frequencies. Stack the Zenith II Extreme with your favorite modules and maximize latest Threadripper CPU throughput for applications that demand massive bandwidth, or balance Infinity Fabric and memory performance for a diverse range of workloads.

Zenith II Extreme features a differential-sensing circuit that simplifies overclocking and tuning by allowing you to track voltages more accurately.
ROG Zenith II Extreme 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.
The TRX40 platform is aimed at the most discerning content creators, so Zenith II Extreme implements the latest USB standards. Ready-to-use ports are located on the rear I/O panel, and there are front-panel connectors on the motherboard to let you put USB right where you need it.
The ROG Zenith II Extreme is compatible with the latest USB 3.2 Gen 2×2. This newest USB standard doubles the transfer bandwidth by opening another USB 3.2 Gen 2 lane to achieve its maximum throughput of up to 20 Gbps.
