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.
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.
CPU Potential We created a proprietary algorithm that evaluates the capabilities of your CPU
Cooling Capability The onboard intelligence also watches system vitals like temperatures, fan speeds, and power draw to gauge cooling performance
AI Overclocking Utilizes onboard intelligence to perform automated clocking and provides target frequency and voltage estimations for savvy veterans that prefer manual tuning
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.

The TurboV Processing Unit (TPU) provides AI Suite 3 with the intelligence needed to automatically fine-tune voltages, monitor system stats, and adjust overclocking settings. We have upgraded this tool to provide AI Overclocking prediction values for users who want more insight when experimenting with different settings.
The Energy Processing Unit (EPU) enables system-wide power efficiency to automatically optimize power consumption to maximize energy savings. This tool now features temperature regulation that adjusts the CPU frequency according to processor temperatures. Users can now set a threshold to balance temperature and performance.
With Prime Z390-A you have comprehensive control over fans via Fan Expert 4 or our media-acclaimed UEFI. Whether you're cooling with air or water, Auto-Tuning mode intelligently configures all parameters with a single click. There's also an Extreme Quiet mode, which reduces all fan speeds to below the default minimum — keeping your system whisper-quiet when performing light tasks.
Digi+ delivers real-time control over voltage droop, switching frequency and power -efficiency settings, allowing you to fine-tune CPU voltage regulation for ultimate stability and performance.
Whether you're a professional designer or hardcore gamer, you'll feel the benefit of the ASUS-exclusive Turbo App every day.

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.
Top layer – ground ring to prevent lateral interference
Tested by using Synopsys HSPICE simulation software
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.
Prime Z390-A features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS.

A dedicated header that supplies over 3A for high-performance PWM or DC water pumps, plus a second dedicated header for AIOs.
Each onboard header supports auto-detection of PWM or DC fans.
Includes three additional DC or PWM fan headers, plus three thermal-probe headers.
A dedicated integrated circuit protects each fan header from over-temperature and over-current.
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.
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.
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.
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.
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.
