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.
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.
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
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.
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.
5X Protection III
Prime series motherboards are engineered with industry-leading 5X Protection III, employing the finest components, excellent circuit design, and exacting standards to guarantee the quality and long-term durability of your motherboard.
Fortified PCIe slot prevents damage
SafeSlot Core is the ASUS-exclusive PCIe slot. Featuring a fortified design that’s anchored to the motherboard by a special hook, Safeslot Core provides 1.6X-stronger retention and 1.3X-greater shearing resistance than standard expansion slots.
Pumped-up throughput, 2.5X-higher surge tolerance
ASUS LANGuard is hardware-level networking protection that employs signal-coupling technology and premium anti-EMI surface-mounted capacitors to ensure a more reliable connection and better throughput.
World-class circuit-protecting power design
An exclusive circuit design with built-in voltage regulators to protect your motherboard from damage caused by unexpected high-level voltages from unstable or inferior power supplies.
Precision control for stable power
ASUS-exclusive DIGI VRM intelligently delivers power to the processor based on real-time demands, reducing energy waste and improving system stability.
DRAM Overcurrent Protection
Short-circuit damage prevention
Onboard resettable fuses prevent overcurrent and short-circuit damage. This extends beyond I/O ports to DRAM to safeguard the lifespan of your system and connected devices.
Stainless-Steel Back I/O
3X corrosion-resistance for greater durability
Corrosion-resistant stainless-steel back I/O panels bonded with chromium oxide have a lifespan that’s three times longer than ordinary panels.
Electrostatic discharge protection
ASUS ESD Guards prevent damage from electrostatic discharge, up to /- 10kV for air discharge and /- 6kV for contact discharge, arranged in an active-protective-circuit design that prolongs the life of components.
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.
* The 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 Strips are sold separately.
