Prime

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.
All-round energy efficiency

With the Energy Processing Unit (EPU) you'll enjoy system-wide power savings. The EPU automatically optimizes power consumption and maximizes savings with Away mode. — a smart setting that creates an extreme energy-saving scenario by shutting down unused I/O controllers.

Flexible cooling controls for air or liquid

With Prime Z390-P you have comprehensive control over fans via Fan Xpert 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.

Media-acclaimed UEFI BIOS

The UEFI BIOS is an early waypoint on any PC-building journey, and Prime Z390-P offers one of the best in the business.

OptiMem II

Reimagined from the ground up

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

Mem! OK II

Automated Recovery

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

Cooler by design

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

Each header can dynamically reference three thermal sensors, and via Fan Xpert 4 you can even map the temperature of supported ASUS graphics cards to optimize cooling for GPU and CPU-intensive tasks.

A dedicated PWM/DC header for self-contained water-cooling setups.

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

A dedicated integrated circuit protects each fan header from over-temperature and over-current.

Enhanced power delivery

Prime Z390-P adjusts power delivery based on the number of power phases, optimizing power and efficiency for the latest Intel processors.

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.
