ASUS OptiMem II Technology

ASUS OptiMem II Technology

INCLUDING MEMOK! II AUTOMATED RECOVERYTo 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 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.

Ultra-fast Connectivity

On-board M.2

SPEED UP WITH ON-BOARD M.2 UP TO 32GBPSWith x4 PCI Express 3.0/2.0 bandwidth, M.2 supports up to 32Gbps data-transfer speeds. It’s the perfect choice for an operating system or application drive, providing fast access to data.

ASUS Lighting Control


BRIGHTEN UP YOUR BUILDA well-tuned enthusiast system deserves a matching aesthetic. With 5050 RGB strips connected to the RGB header, you can create your own stunning multicolour 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.

Outstanding Audio

Audio Capacitors

INTELLIGENT DESIGN & PREMIUM HARDWAREDiscover sound quality unlike anything you've experienced before with special audio features on the Prime Z390 series motherboards. Audio shielding separates analog/digital signal domains, significantly reducing multi-lateral interference. A separate layer for left and right tracks ensures minimal crosstalk between audio paths. Designed with premium Japanese-made audio capacitors, which provides an immersive sound signature with exceptional fidelity.

Comprehensive Cooling Controls

Multiple Temperature Sources

MULTIPLE TEMPERATURE SOURCESEach header can be set to monitor and react to up to three thermal sensors. Via Fan Xpert, you can also assign a sensor to monitor the temperature of supported ASUS graphics cards to ensure optimal cooling during GPU- or CPU-intensive workloads.

Enhanced Power Delivery

Enhanced Power Delivery

MAXIMUM POWER & EFFICIENCYPrime Z390M-PLUS adjusts power delivery based on the number of power phases, optimizing power and efficiency for the latest Intel processors.

ProCool Power Connector

ProCool Power Connector

BUILT TO PREVENT CONNECTOR FAILURECompared 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.

ASUS SafeSlot Protection

safe slot core

PREMIUM ASUS TECHNOLOGYSafeSlot 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. ASUS Prime motherboards have strengthened solder points around both the PCIe and DIMM pins.

Ultra-durable ASUS Protection

TRUSTWORTHY STABILITY AND COMPATIBILITYPrime Z390M-PLUS is designed for builders who want essential ASUS reliability and performance. More CPU cores create power-delivery challenges, so Prime Z390M-PLUS has extra power phases and comprehensive cooling features for optimal performance.


LANGUARDASUS 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.

Overvoltage Protection
