PRIME Z370-A II
ASUS Prime Z370 Series motherboards provide the solid foundation needed for your first build, plus loads of scope to grow with your ambitions. 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 which include automated system tuning, comprehensive cooling controls, immersive onboard audio, and support for the ASUS Fan Extension Card.

Ultrafast Connectivity
With 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.

M.2 heatsink
PRIME Z370-A II has an ultra-efficient heatsink to reduce M.2 SSD temperatures by up to 20°C and that means optimal storage performance and improved SSD longevity.

USB 3.1 Gen 2 Type-A & Type-C
With backward-compatible USB 3.1 Gen 2 Type-A and reversible USB 3.1 Gen 2 Type-C ports, you'll experience ultimate connection flexibility and blazing data-transfer speeds of up to 10Gbps.

ThunderboltEX 3 Card Support
PRIME Z370-A II provides full support for a ThunderboltEX 3 card. An Intel-certified Thunderbolt 3 add-on card enables breathtaking bi-directional speeds of up to 40Gbps through a single cable up to 4X faster than other PC data-transfer protocols.

Cooler by design
PRIME Z370-A II features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS.
- Multiple temperature sources: Each header can monitor and react to dedicated thermal sensors.
- AIO pump: A dedicated PWM/DC header for self-contained water-cooling setups.
- 4-pin PWM/DC fan: A dedicated PWM/DC header for self-contained water-cooling setups.
- Smart protection: Each onboard header supports auto-detection of PWM or DC fans.
- ASUS Fan Holder: With the Fan Holder and fan in place, VRM temperatures are reduced by up to 25 degrees.

Improved DDR4 stability
ASUS OptiMem preserves memory signal integrity by routing traces and vias to the optimal PCB layer, and our T-Topology trace layout ensures time-aligned signaling by balancing trace lengths between memory slots.

All-round energy efficiency
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
With Prime 300 Series motherboards you have comprehensive control over fans, water pumps, and even all-in-one (AIO) coolers ― all via Fan Expert 4 Core. Whether you're cooling with air or water, Auto-Tuning mode intelligently configures all parameters with a single click.

Intel Optane memory ready
Intel Optane™ is a revolutionary non-volatile memory technology supported by Prime 300 Series motherboards. Intel Optane memory modules accelerate attached storage to reduce boot and load times, so everything feels faster and more responsive.
