ASUS PRIME Z390-A LGA1151 ATX Motherboard

- Replaces the ASUS PRIME Z370-A II LGA1151 ATX Motherboard

The ASUS PRIME Z390-A motherboard supports 8th and 9th Generation Intel Core processors in the LGA1151 package. It has two 32GB/s M.2 slots, onboard Intel Gigabit LAN, DDR4 support and DisplayPort and HDMI outputs.


  1. Socket 1151 ATX motherboard with Intel Z390 chipset
  2. Supports Intel 8th and 9th Generation CPUs
  3. 4x DDR4 DIMM sockets (max. 64 GB)
  4. DisplayPort and HDMI Outputs
  5. 3x PCIe x16 and 3x PCIe x1
  6. 6x SATA 6Gb/s, 2x M.2, Intel Optane Memory
  7. 1x USB 3.1 Type-C, 5x USB 3.1 Type-A, 2x USB 2.0, Optical S/PDIF, LAN

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. ASUS AI Overclocking makes automatic tuning faster and smarter than ever before. Available in Windows or directly through the UEFI, it profiles the CPU and cooling to predict the optimal configuration for each individual system.

USB 3.1 Gen 2 Type-A and 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.

5-Way Optimisation

Take care of complex tuning with just one click. ASUS 5-Way Optimisation is a system-wide tuning utility that overclocks the processor and tunes fan speeds to ensure the best balance between cooling and acoustics. The automated CPU tuning feature of 5-Way Optimisation leverages the same onboard intelligence as AI Overclocking, but goes further by running a Prime95 based stress test to deliver a result that's well-tuned from the get-go.

Media-acclaimed UEFI BIOS

The UEFI BIOS is an early waypoint on any PC-building journey, and Prime Z390-A offers one of the best in the business.

OptiMem II - DDR4 OC 4266+MHz

To provide Intel's latest processors unfettered access to memory bandwidth, we've reimagined motherboard trace routing from the ground up. ASUS 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 customised T-Topology layout that delivers time-aligned signalling.

Cooler by design

Prime Z390-A features the most comprehensive cooling controls ever, configurable via Fan Xpert 4 or the UEFI BIOS.

Outshine the competition

A well-tuned enthusiast system deserves a matching aesthetic. ASUS Aura offers full RGB lighting control with a variety of functional presets for the built-in RGB LEDs as well as strips connected to the onboard RGB headers. And it can all be synced with an ever-growing portfolio of Aura-capable ASUS hardware.
