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.

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.

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.

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.

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

Asus Lighting Control

Brighten up your build

With 5050 RGB strips connected to the RGB header; you can create your own stunning multicolor lighting displays with static; blinking; fading; and strobing effects.
