    AI Networking

    GameFirst VI optimises and organises network bandwidth, effectively reducing jitter and eliminating spike lag to ensure smooth online gameplay.










    Maximus XII Extreme is the ideal foundation for your dream gaming build. An intelligent voltage-regulator module (VRM) design and high-quality components ensure that you'll get the most out of demanding latest-generation Intel processors. More firepower and an overclocking edge are yours with Maximus XII Extreme.






    Power Solution


    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 utilising teamed power stages to rapidly swing current, while maintaining exemplary thermal performance.








    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 optimise 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 Extreme with your favourite modules and maximise throughput of the new 10th Generation Intel Core Comet Lake-S processor for applications that demand massive bandwidth.










    Featuring premium components, multiple fan headers and a bundled fan extension card, Maximus XII Extreme is fully equipped to enable higher performance at lower temperatures. To ensure system stability under heavy CPU loads, Maximus XII Extreme employs large VRM and chipset heatsinks that strike the right balance between surface area and mass. The extra-large heatsinks also cover multiple M.2 slots.








    Cooling Heatsinks

    Maximus XII Extreme delivers exceptional overclocking performance without requiring a fan for cooling. This is possible thanks to 16 teamed power stages running 90A MOSFETs on it VRM layout. To further improve heat dissipation, the I/O cover act as a large heatsink and there is also a heat pipe bridging the VRM heatsinks, increasing surface area and improving heat dissipation.


    VRM heatsink

    A VRM heatsink is placed on the MOSFETs and chokes, and the embedded heatpipe connects to the aluminium I/O cover.


    Aluminium I/O cover

    An aluminium I/O cover is connected to the primary heatsink via an embedded heatpipe, increasing mass and surface area for dissipation.


    Extended VRM Heatsink

    Helps cool vital motherboard power delivery areas to enhance the overclocking potential of future processors.


    Aluminium heatsink cover

    The heatsink cover is crafted from pure aluminium to efficiently cool the two onboard M.2 drives.


    High-conductivity thermal pad

    The high-quality thermal pad improves overall heat transfer from the system by bridging the heat generated by the power stages to the heatsink.


    Solid steel backplate

    A steel, cold-rolled coil construction backplate strengthens the motherboard to prevent bending, and adds additional mass to siphon heat from the VRM.


    Chipset heatsink

    A chipset heatsink blends seamlessly with the aluminium heatsink cover and prominently features the ROG logo.








    Cooler by Design

    ROG Maximus XII Extreme features the most comprehensive cooling options ever.


    Multiple temperature sources

    Each header can be set to monitor and react to three user-configurable thermal sensors for workload-based cooling. And all settings can be easily managed by Fan Xpert 4 or UEFI.


    4-pin PWM/DC fan

    Every onboard header supports auto-detection of PWM or DC fans.


    Bundled Fan Extension Card II

    Bundled cand includes six additional DC or PWM fan headers, plus three thermal-probe headers.






    ROG Water-Cooling Zone


    Dual water-temperature headers and a flow-rate header feed information straight into the AI Suite utility, allowing you to track coolant temperatures and the flow rate of the entire loop.


    Water pump+

    A dedicated header can supply over 3 amps to high-performance PWM or DC water pumps.


    Water in/out

    A dedicated header enables monitoring of temperatures at the input/output points of any component.


    Water flow

    A dedicated header enables constant monitoring of flow rate throughout the entire loop.
