  • Intel® LGA 1200 Socket: Ready for 10th Gen Intel® Core™ processors
  • Enhanced Power Solution: 12+2 DrMOS power stages, 6-layer PCB, ProCool, alloy chokes and durable caps for stable power delivery
  • AI Overclocking: Quickly optimizes CPU performance based on the CPU and cooler, for results that extremely close to expert manual tuning
  • AI Cooling: Manages and controls all motherboard fans, automatically optimizing settings based on current system load and temperature
  • 5-Way Optimization: One-click, system-wide tuning delivers optimized overclocking and intelligent cooling for CPU or GPU-intensive tasks
  • Comprehensive Cooling: VRM heatsink, M.2 heatsink, hybrid fan headers and Fan Xpert 4
  • Next-gen connectivity: Intel® 2.5 Gb Ethernet, front USB 3.2 Gen 2 Type-C® and Thunderbolt™ 3 header support

5-Way Optimization

ASUS 5-Way Optimization makes your PC smart, taking care of complex tuning with one click. It dynamically optimizes essential system specs, providing overclocking and cooling profiles that are tailored for your rig.

  • 5-Way Optimization is an automated tuning utility that optimizes overclocking and cooling profiles for your unique system configuration
  • Fans stay whisper-quiet for everyday computing, and deliver optimal airflow when the system is crunching CPU or GPU intensive tasks
  • A stress test feature allows you to optimize and overclock for CPU- or memory-centric workloads



Cool to the Core

Prime Z490 series is engineered with multiple onboard heatsinks and an array of hybrid fan headers to ensure your rig stays cool and stable under intense workloads.

  • M.2 Heatsink
    An M.2 drive sits under a passive heatsink to ward off the throttling that can occur with sustained transfers. The heatsink is held in place by easily-removable captive screws, giving you the flexibility to move it to another M.2 slot
  • VRM Heatsink and Thermal Pads
    Two massive VRM heatsinks with underneath thermal pads improve heat transfer from the MOSFETs and chokes for better cooling performance. A bundled fan holder provides additional cooling options
  • Stack Cool 3+
    2-ounce copper layers draw heat away from critical components to keep them at their optimal operating temperatures

Build on a Solid Foundation

Prime Z490 series is built to handle the additional cores and increased bandwidth of 10th Generation Intel® Core™ processors. A Z490 motherboard provides all the fundamentals to boost daily productivity, so your system will be ready for action with stable power, intuitive cooling and flexible transfer options.

Robust Power Design
Stable power is essential to extract every last bit of performance out of 10th Gen Intel Core processors, Prime Z490 motherboard is geared to cater to the demands of these high-core count CPUs.

  • ProCool Connectors
    Proprietary connectors augment the motherboard's link to the PSU with 8+4 pin connectors that pass 12 volts of power directly to the processors. Each jack features solid pins that can handle more current than hollow-pin connectors
  • 12+2 DrMOS Power Stages
    A VRM with 12+2 DrMOS power stages delivers the power and efficiency that the latest Intel processors demand

Revisions to the motherboard's trace routing provide the latest Intel processors with unrestricted access to memory bandwidth. ASUS OptiMem II technology carefully maps memory signal pathways across different PCB layers to reduce vias and adds shielding zones that significantly reduce crosstalk.

  • ASUS OptiMem II Benefits:
    • Improved memory stability and compatibility
    • Allows lower memory latencies at equivalent voltages
    • Improved memory frequency margins

Dual NVMe PCIe x4 M.2 Slots
Dual M.2 slots support data-transfer speeds of up to 32 Gbps via PCI Express® x4 3.0 bandwidth, enabling quicker boot-up and app load times with OS or application drives.
* Actual transmission speeds will be lower than the theoretical maximum speed.

USB 3.2 Gen 2 Type-C + Type-A Port and Connectors
Numerous USB ports support high-end rigs loaded with peripherals, including a front-panel USB Type-C® connector with fast USB 3.2 Gen 2 (10Gbps) connectivity for compatible cases.

Little Things Make a Big Difference

Prime Z490 series adds the nuanced details that improve every experience, from exclusive codecs that provide pristine audio quality to intuitive RGB lighting controls that let you customize your system to create a uniquely personal look.


Exclusive CODECs
Realtek Codec and Unique Design Features for Pristine, Powerful Audio:

  • Realtek S1220A Chipset
    Prime Z490-A utilizes a unique audio codec designed in close collaboration with Realtek — the Realtek S1220A. It also features an unprecedented 120 dB signal-to-noise ratio for the stereo line out and a 113 dB SNR for the line in, providing pristine audio quality. Additionally, an impedance-sensing circuit automatically adjusts gain to ensure an optimal volume range for your headphones
  • DTS:X® Ultra
    DTS:X® Ultra adds a spatial audio feature to boost headphones and speakers for enhanced gaming, VR, and extended-reality experiences. DTS:X Ultra supports sound based on channels, scenes, and objects to allow for deeper sonic immersion in enabled content. It also provides post-processing enhancements and device-level tuning for DTS® codecs

Crystal Sound 3
Flawless Audio that Immerses You in the Game

  • Power Pre-Regulator
    Reduces power-input noise to ensure consistent performance
  • Audio Shielding
    Separates analog/digital signal domains, significantly reducing multi-lateral interference
  • Separate Layer for Left and Right Tracks
    Ensures minimal crosstalk between audio paths
  • Integrated Amplifier
    Capable of driving high-impedance headphones, without rolling-off high or low frequencies
  • De-Pop Circuit
    Reduces start-up popping noise to all audio outputs
  • Premium Japanese Capacitors
    Premium parts provide an immersive sound signature, with exceptional fidelity


Aura Sync Outshines 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 and devices connected to the onboard RGB headers - and it can all be synced with an ever-growing portfolio of Aura-capable hardware.

Addressable Gen 2 RGB Header
Two addressable Gen 2 RGB headers are now capable of detecting the number of LEDs on second-gen addressable RGB devices, allowing the software to automatically tailor lighting effects to specific devices. The new headers also offer backward-compatibility with existing Aura RGB gear.

Armoury Crate
This is a new software utility designed to give you centralized control of supported products. From a single intuitive interface, Armoury Crate allows you to easily customize RGB lighting and effects for every compatible device in your arsenal. The software also provides control of settings for an ever-growing number of ASUS products, including keyboard and mouse preferences. Armoury Crate even features dedicated product registration and highlight to help you stay in touch with the ASUS community.
