We've melded all the good stuff that's packed into the latest Intel processors with essential ASUS design and engineering, so you benefit from industry-leading technologies — including automated system tuning, comprehensive cooling controls, immersive onboard audio, and support for the ASUS Fan Extension Card. Build smart and easy with ASUS Prime Z370.

Power delivery enhancements

DR. MOS

The Prime Z370-A II'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.

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.

Tune it your way

5-Way Optimization

One-click overclock and cooling, done!

ASUS 5-Way Optimization makes your PC smart. One click takes care of complex tuning, dynamically optimizing essential aspects of the system to provide overclocking and cooling profiles that are tailored for your rig.

An automated tuning utility that optimizes overclocking and cooling profiles for your unique system configuration.

Fans stay whisper-quiet with everyday computing, and deliver optimal airflow when the system is crunching through CPU or GPU-intensive tasks.

Stress test function helps optimize and overclock for CPU- or memory-centric workloads.

CPU performance boost

Unleash your PC's full performance with the ASUS AI Suite 3 utility. The TurboV Processing Unit (TPU) is the intelligence behind our automated system-tuning utility, offering the ability to fine-tune voltages, monitor system stats, and adjust overclock parameters for optimal performance.

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 Z370-A II you have comprehensive control over fans, water pumps, and even all-in-one (AIO) coolers ― all 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 Extreme Quiet mode, which reduces all fan speeds to below the default minimum — keeping your system whisper-quiet when performing light tasks.

Precise digital power control

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.

App specific optimization for professionals and gamers

Whether you're a professional designer or hardcore gamer, you'll feel the benefit of the ASUS-exclusive Turbo App. This intuitive tool allows you to define CPU overclocking, apply fan profiles, prioritize network data and optimize audio settings at app level ― so your PRIME Z370-A II system is perfectly optimized for whatever you're doing.

Make your memory go faster

ASUS OptiMem preserves memory signal integrity by routing memory traces and vias to the optimal PCB layer, and our T-Topology layout ensures time-aligned signaling by balancing trace lengths between memory slots. These enhancements lead to more headroom for overclocking and improved stability, allowing memory speeds of DDR4-4000 and beyond with all slots populated.

Cooler by design

PRIME Z370-A II features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS.

Each header can be set to monitor and react to three thermal sensors, and via Fan Xpert 4 you can even assign a sensor to monitor the temperature of supported ASUS graphics cards — for optimal cooling during GPU- or CPU-intensive workloads.

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

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.

ASUS Fan Holder

With the all-new ASUS Fan Holder increasing airflow your Prime Z370 Series motherboard's VRM area is simple. Just screw on a 40/50mm fan, mount the bracket on the heatsink, and hook the fan up to a header for a targeted cooling boost. With the Fan Holder and fan in place, VRM temperatures are reduced by up to 25^oC — perfect for your overclocking adventures.
