Teamed Power Architecture
Today’s CPU architectures place incredible demands on motherboard power design by transitioning from deep power saving modes , going from lower-power mode to full load in an instant. Our latest VRM architecture rises to the challenge by utilizing teamed power stages to rapidly swing current, while maintaining exemplary thermal performance.
A brief history
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.
A shift in CPU demands
While doublers help extend the number of effective phases, they do so at the cost of a processing delay.
However, today’s CPUs now pack more cores than their predecessors, and the latest instruction sets allow them to crunch computationally dense workloads at an incredible pace. In addition, they consume less power at idle and can transition between load 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.
Bucking the trend
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 Maximus XII Formula 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 Maximus XII Formula utilizes 16 power stages. The power stage 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.

ASUS OPTIMEM III
Boasting proprietary memory trace layout tweaks that improve signal integrity and mitigate noise, ASUS OptiMem III is more compatible with 3600 MHz+ memory kits, allowing them to run at higher frequencies. You can opt to optimize memory for high frequency settings, or low latency settings. With higher capacity memory kits, OptiMem III enables you to run at maximum frequency, whereas other motherboards will trade off frequency for capacity. Stack Maximus XII Formula with your favorite modules and maximize throughput of the new 10th Generation Intel® Core™ Comet Lake-S processor for applications that demand massive bandwidth.
The focus on maximizing performance would be futile without similar dedication to improving the cooling that allows systems to sustain faster speeds. The CrossChill EK III VRM block enables Maximus XII Formula to cope with the high VRM loads of ten core CPUs. The hybrid cooling system sits atop of a heatpipe that’s directly linked to the extended VRM heatsink, giving it cooling capabilities that surpass the requirements of this current generation.
CrossChill EK III lets you cool with air and water. The redesigned copper cooling channel is wider to provide up to 37.2°C-lower MOSFET temperatures on water, while the standard G1/4" threaded fittings allow it to fit existing setups for efficient, quiet cooling with minimum effort.
