  • ASUS Prime Z390-A LGA1151 (Intel 8th and 9th Gen) ATX DDR4 DP HDMI M.2 USB 3.1 G

    Dressed in professional attire, the Prime Z390 series caters to daily users and content creators with well-rounded specs and features. Combining the benefits of the latest processors with essential ASUS design and engineering, Prime Z390 provides a wealth of options for performance tuning via intuitive software and firmware features.


    Tune it your way

    Prime Z390 simplifies CPU overclocking with software and extensive tweaking options that give beginners and seasoned overclockers alike the tools to build well-tuned machines. A new memory trace layout provides stability and compatibility for both traditional DIMMs and RGB-infused memory, letting you pair a broad choice of DRAM kits with your build.


    AI Overclocking

    ASUS AI Overclocking makes automatic tuning faster and smarter than ever before. Available in Windows or directly through the UEFI, it profiles the CPU and cooling to predict the optimal configuration for each individual system.

    5-way Optimization

    Overclocking Intelligence

    Take care of complex tuning with just one click. ASUS 5-Way Optimization is a system-wide tuning utility that overclocks the processor and tunes fan speeds to ensure the best balance between cooling and acoustics. The automated CPU tuning feature of 5-Way Optimization leverages the same onboard intelligence as AI Overclocking, but goes further by running a Prime95 based stress test to deliver a result that's well-tuned from the get-go.


    OptiMem II

    DDR4 OC 4266+MHz

    To provide Intel's latest processors' unfettered access to memory bandwidth, we've reimagined motherboard trace routing from the ground up.  Our OptiMem II tech carefully maps memory signal pathways across different PCB layers to reduce vias and also adds shielding zones that significantly reduce crosstalk. And to further enhance overclocking headroom for fully stacked memory configurations, we've employed a highly customized T-Topology layout that delivers time-aligned signaling.


    MemOK! II

    Automated Recovery

    MemOK! II automatically fixes boot failures that arise due to memory overclocking and instability. When a DRAM-related POST error occurs, the motherboard adjusts memory parameters until the system is able to start.

    Cool and Reliable


    Prime Z390-A is designed for builders who want essential ASUS reliability and performance. More CPU cores create power-delivery challenges, so Prime Z390-A has extra power phases and comprehensive cooling features for optimal performance.


    Cooler by design

    Prime Z390-A features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS.


    M.2 heatsink

    Keep your SSD cooler

    Prime Z390-A has an ultra-efficient heatsink to reduce M.2 SSD temperatures by up to 20°C — and that means optimal storage performance and improved SSD longevity.


    DR. MOS

    The Prime Z390-A's CPU VRM utilizes Dr. MOS power stages that combine high-side and low-side MOSFETs and drivers into a single package, delivering the power and efficiency that Intel's latest processors demand.


    ProCool power connector

    Compared with traditional power inputs, ProCool sockets are built to tight specifications to ensure flush contact with the PSU power lines. This lowers impedance, which helps to prevent hotspots and connector failure.



    Protect your graphics card investment

    SafeSlot is the PCIe slot reinvented by ASUS and engineered to provide superior retention and shearing resistance. Manufactured in a single step using a new insert-molding process, SafeSlot integrates the slot with fortifying metal for an inherently stronger slot, which is then firmly anchored to the PCB through additional solder points.


    Built to Last

    ASUS motherboards are exhaustively tested for compatibility with more than 1,000 components and devices, and each new model undergoes a minimum of 8,000 hours of strict validation — offering the peace of mind of knowing that your ASUS motherboard is fit for all environments and applications.

    Visual beauty


    Aura Sync

    Outshine the competition

    A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for the built-in RGB LEDs as well as strips connected to the onboard RGB headers.* And it can all be synced with an ever-growing portfolio of Aura-capable


    ASUS hardware.

    * The Aura RGB-strip header supports 5050 RGB LED strips with a max power rating of 3A (12V). For maximum brightness, strip length should not exceed 3m. 
    ** RGB LED Extension cables are included. LED Strips and Aura-compatible devices are sold separately. 

    Upgrade to unrivalled audio


    Outstanding audio

    Realtek codec and unique design features for pristine, powerful audio

    Prime Z390-A utilizes a unique audio codec designed in close collaboration with Realtek — the Realtek S1220A. It also features an unprecedented 120dB signal-to-noise ratio for the stereo line-out and a 113dB SNR for the line-in, providing pristine audio quality. Additionally, a new impedance-sensing circuit automatically adjusts gain to ensure the optimal volume range for your headphones.


    DTS Headphone:X™

    Surround sound

    Immersive 3D surround-sound technology provides incredible audio experiences.


    Crystal Sound 3

    Flawless audio that immerses you in the game


    Power pre-regulator

    Reduces power-input noise to ensure consistent performance.


    Audio shielding

    Separates analog/digital signal domains, significantly reducing multi-lateral interference.


    Separate layer for left and right tracks

    Ensures minimal crosstalk between audio paths.


    Integrated amplifier

    Capable of driving high-impedance headphones, without rolling-off high or low frequencies.


    De-pop circuit

    Reduces start-up popping noise to all audio outputs.


    Premium Japanese-made audio capacitors

    Premium parts provide an immersive sound signature, with exceptional fidelity.
