NPU Boost

The integrated NPU in Intel^® Core™ Ultra Processors (Series 2) efficiently accelerates AI workflows — and NPU Boost lets you do more with it. This BIOS feature overclocks the NPU with just one click, increasing performance by up to 24%.

* This feature only supports Intel K series processors.
** The overclocking performance may vary depending on the CPU series and motherboard used.
*** Testing was conducted with an Intel Arrow Lake QS Q2HA Ultra 9 285K processor, ROG Maximus Z890 Extreme motherboard, GeForce RTX™ 4090 24GB graphics card, and XPG Lancer DDR5 memory modules (model AX5U6000C4016G).

Power Design

• Robust power design

  10(80A) + 1(80A) + 2(80A) + 1(80A) power stages that integrate high-side and low-side MOSFETs and drivers into packages rated for up to 80 amperes each. This configuration ensures optimal power delivery, efficiency, stability and performance for both current and future Intel® processors.

• Six-Layer PCB Design

  The multi-layered printed circuit board design quickly dissipates heat around the voltage regulators to improve overall system stability and provide the CPU with more overclocking headroom.

• ProCool Connectors

  Proprietary connectors augment the motherboard’s link to the power supply with 8 + 4 pin connectors that pass 12 volts of power directly to the processor. Each connector features solid pins that can handle more current than hollow-pin connectors.

• Digi+ VRM Control

  The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings.

AEMP III for Ultimate DDR5 Performance

ASUS Enhanced Memory Profile III (AEMP III) is an advanced firmware feature that empowers users to achieve unparalleled memory performance with cutting-edge CUDIMM memory. Through a two-phase comprehensive tuning process, AEMP III first optimizes the clock driver and then the memory frequency. This results in the best balance between performance and stability, even at cutting-edge speeds of DDR5-7600 or higher.*

*Results may vary according to individual system specifications. Currently, only 2-DIMM configurations are supported. Results are based on a test with an Intel Core Ultra 9 285K processor and 2x16GB SK Hynix DDR5-6400 Clocked Unbuffered DIMM RAM, model HMCG78AHBCA326N.

  DIMM Fit

  DIMM Fit is an ASUS-exclusive BIOS feature that precisely analyzes individual memory modules to optimize performance and pinpoint potential issues. This offers peak efficiency, compatibility, and system stability. Whether you are an overclocker seeking ultimate performance, a competitor pursuing the most responsive gameplay, or a content creator prioritizing rock-solid stability, DIMM Fit provides optimizations tailored to your needs and your hardware configuration.

• 

  Three M.2 ????slots (up to 128Gbps)

  The PRIME Z890M-PLUS WIFI offers a total of three M.2 slots, including one that supports data-transfer speeds of up to 128Gbps via PCIe 5.0, two that support 64Gbps via PCIe 4.0. This enables quicker boot-up and app load times with OS or application drives.*

  *Actual transmission speeds will be lower than the theoretical maximum speed.

Cooler by design

The Prime Z890M-PLUS WIFI motherboard is engineered with multiple onboard heatsinks and an array of hybrid fan headers to help ensure your rig stays cool and stable under intense workloads.

• AIO pump header

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

• VRM heatsinks and thermal pads

  The massive VRM heatsinks and essential thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance.

• Multiple temperature sources

  Each header can dynamically reference three thermal sensors. Fan Xpert 4 lets you to map the temperature of supported ASUS graphics cards to optimize cooling for GPU- and CPU-intensive tasks.

• 4-Pin PWM/DC fan

  Each onboard header supports auto-detection of PWM or DC fans.

• Passive chipset heatsink

  An aluminum passive chipset heatsink ensures optimal cooling and stable performance. It is more durable and longer-lasting than heatsinks with fans, which can be vulnerable to the buildup of dust and debris.

• Smart protection

  A dedicated integrated circuit protects each fan header from overheating and excess current.

Smart cooling precision

• 

  ASUS Fan Xpert 4

  ASUS Fan Xpert 4 software offers comprehensive control over fans and AIO coolers. Auto-Tuning mode configures settings with one click, while Extreme Quiet mode reduces fan speeds for silent operation during light tasks. Controls are also available via the UEFI BIOS.
