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.
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.
TPU
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.
EPU
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.
Fan Xpert 4
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.
Digi+ VRM Control
Precise Digital Power Control
The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings. It also allows you to fine-tune your CPU for ultimate stability and performance.
Turbo App
App-Specific Optimization
Turbo App allows you to define CPU overclocking, apply fan profiles, prioritize network data and optimize audio settings at the app level, so your system is set up exactly as needed.
UEFI BIOS
The renowned ASUS UEFI BIOS provides everything you need to configure, tweak and tune your system. It offers intelligently simplified options for PC DIY beginners, as well as comprehensive features for seasoned veterans.
Advanced Mode
Advanced Tuning for Serious Tweakers
An intuitive Advanced mode offered via the UEFI lets you take complete control. A built-in search feature makes it easy to find options, and various Advanced functions let you intelligently make nuanced adjustments so you can dial in performance just the way you want.
EZ Mode
Quick and Simple Setup
EZ mode displays vital settings and stats and also offers guided wizards, drag-and-drop functionality, and one-click application of important settings — all to help you get your rig up and running in no time.
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.
Heatsinks
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
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.
SoC VRM Heatsink
Stack Cool 3+
2-ounce copper layers draw heat away from critical components to keep them at their optimal operating temperatures.
Cooler by Design
Prime Z490 series features comprehensive cooling controls that are configurable via Fan Xpert 4 software or via the UEFI BIOS.
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 Power Stages
A VRM with 12+2 power stages delivers the power and efficiency that the latest Intel processors demand.
ASUS OptiMem II
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:
Dual M.2 (up to 32 Gbps)
Dual M.2 slots support data-transfer speeds of up to 32 Gbps via x4 PCI Express® 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-A & Type-C
Numerous USB ports support high-end rigs loaded with peripherals, including a front-panel USB Type-C® connectors with fast USB 3.2 Gen 2 connectivity for compatible cases.
Thunderbolt™ 3 Support
Prime Z490-A supports ThunderboltEX 3-TR, an Intel certified Thunderbolt™ 3 add-on card that enables bi-directional speeds of up to 40 Gbps via a single cable. Additionally, an integrated Thunderbolt 3 header can support up to six devices in a daisy-chain and provide up to 100 watts of power to fast-charge devices.
Intel Ethernet
Intel® 2.5 Gb Ethernet
Intel Ethernet Connection I225-V reduces CPU overhead and offers exceptionally high TCP and UDP throughput for faster, smoother data transfer.
LANGuard
ASUS LANGuard is a hardware-level network protection feature that integrates advanced signal-coupling technology and premium anti-EMI surface-mounted capacitors to improve throughput and ensure a more reliable connection.
Turbo LAN
Turbo LAN with cFosSpeed traffic-shaping technology reduces network lag and allows you to adjust application network transmission priorities in just one click.
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 Codec
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.
Crystal Sound 3
