ASUS Prime series is expertly engineered to unleash the full potential of 10th Gen Intel® Core™ processors. Boasting a robust power design, comprehensive cooling solutions and intelligent tuning options, Prime Z490 series motherboards provide daily users and DIY PC builders a range of performance tuning options via intuitive software and firmware features.
Tune It Your Way
Comprehensive controls form the foundation of the ASUS Prime series. The Prime Z490 motherboard packs flexible tools to tune every aspect of your system, enabling you to tweak performance settings to perfectly match the way you work – maximizing your productivity.
5-Way Optimization
ASUS 5-Way Optimization makes your PC smart, taking care of complex tuning with just one click. It dynamically optimizes essential aspects of your system, 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 through CPU- or GPU-intensive tasks.
- A stress test feature allows you to optimize and overclock for CPU- or memory-centric workloads.
CPU Performance Boost
The TurboV Processing Unit (TPU) is an intelligent system-tuning utility that automatically fine-tunes voltages, monitors system stats, and adjusts overclocking parameters for optimal performance.
All-Around Energy Efficiency
The Energy Processing Unit (EPU) automatically optimizes power consumption and maximizes energy savings with Away mode — a smart setting that creates an extreme energy-saving scenario by shutting down unused I/O controllers.
Flexible Air- and Liquid-Cooling Controls
Fan Xpert 4 software provides comprehensive control over fans, water pumps and all-in-one (AiO) coolers. Whether cooling with air or water, an Auto-Tuning mode intelligently configures all parameters with a single click. There’s also an Extreme Quiet mode that reduces all fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans, water pumps and AiO coolers can also be controlled via the UEFI BIOS.
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 Generation 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.
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.
Realtek Codec and Unique Design Features for Pristine, Powerful Audio
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 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.
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.
