RGB FUSION: Set the Color that Matches Your Style
featureAORUS' X299 series motherboards boast the most advanced LED system in the market today. With more customizability than ever and an intuitive UI, you’ll have a blast making your AORUS your own. LED enthusiasts now have even more options with the ability to customize multiple zones. For a more functional use, the bright and vibrant LEDs can be configured to display the PC’s temperature or load. For even more LED goodness RGBW strips are now supported for more true and vibrant whites.

RGB Fusion with Digital LEDs
With AORUS X299 Motherboards, RGB Fusion is even better with Digital LEDs.* RGB Fusion offers users the option to control onboard and external LED light strips for their PC. Already feature filled with colors and patterns, RGB Fusion on X299 Series AORUS Motherboards are now upgraded with Digital LED support. With onboard options and external digital LED strips*, where each LED is digitally addressable, users can experience even more patterns, styles, and illuminations.

AORUS Gaming Motherboards will support either 5v or 12v digital LED strips. RGB Fusion with Digital LEDs comes with 9 new patterns and various speed settings with more to come.
*Digital LEDs are available only on select Motherboards, external LED Strips, Digital LED Strips are not included with Motherboard purchase.

Surround Lighting
Now offering more LED customizations than ever, users can truly adapt their PC to represent their lifestyle. With full RGB support and a redesigned RGB Fusion application, the user has complete control over the LEDs which surround the motherboard.

RGB Fusion (Advanced mode)
With the all new RGB Fusion software, users have access to different preset LED lighting configurations with choice of colors. You can even set the LEDs to synchronize with your favorite music or have them change colors to indicate the CPU temperature. For true lighting experts there is an Advanced Mode, which can be fully customized by individual area with its own effects and color transitions, along with specific duration and transition times.



Don't just make your PC shine, make it a work of art that friends will envy. With the GIGABYTE RGB Fusion mobile app users can watch as they control the lighting within their gaming PC. This gives users ease of access as they try and adjust colors and speeds for different modes, all this can be achieved away from the keyboard and monitor of their PC.

Also Supports RGBW & UV Light Strips
Independently Programmable Onboard Pin Header for RGBW/-UV LED Strips
Not bright enough? You can install standard 12V external RGB, RGBW or RGB/UV light strips on the RGBW pin header and control its color from the RGB Fusion software. Using a RGBW light strip with a dedicated white LED, users will experience brighter and more vibrant shades of colors.

When using RGB/UV LED strips, users can give their systems a fluorescent glow with the use of UV reactive liquid, neon braided cables, and acrylic paint for a wicked-looking gaming PC.

No need to worry when choosing light strips as AORUS motherboards support a wide variety of RGBW/-UV light strips on the market thanks to the RGB Fusion software that allows users to redefine the pin location for the R/G/B Signal.



ALC 1220 120dB SNR HD Audio with Smart Headphone Amp
The ALC1220 is a high-performance multi-channel High Definition Audio Codec with up to 120dB SNR for crystal clear audio and features such as Smart Headphone Amp, 114dB SNR recording for precise voice chats and hardware decoding of DSD128, ensuring users get the best possible audio quality from their PC.

Smart Headphone AMP


Automatically detects impedance of your head-worn audio device, whether earbuds or high-end headphones to provide optimal audio dynamics—preventing issues such as low volume and distortion.


Smart Fan 5
featureWith Smart Fan 5 users can ensure that their gaming PC can maintain its performance while staying cool. Smart Fan 5 allows users to interchange their fan headers to reflect different thermal sensors at different locations on the motherboard. Not only that, with Smart Fan 5 more hybrid fan headers that support both PWM and Voltage mode fans have been introduced to make the motherboard more liquid cooling friendly.

Fan Stop
Achieve fan silence. With Fan Stop map any fan to stop completely when temperatures drop below a specified threshold. Which fan stops, based on readings from which sensor, and at what temperature—all of it can be customized to your liking.


Server-Class Digital Power Design
AORUS X299 series motherboards use an all digital CPU power design from International Rectifier® which includes both 4th Generation digital PWM Controllers and industry-leading 3rd Generation PowIRstage® controllers. These 100% digital controllers offer incredible precision in delivering power to the motherboard's most power-hungry and energy-sensitive components, allowing enthusiasts to get the absolute maximum performance from their new Intel® Core™ X-series CPUs.

IR Digital PWM & IR PowIRstage® ICs
This new generation of IR® digital power controllers and PowIRstage® ICs feature Isense technology, which provide more precise current sensing accuracy. This helps evenly distribute the thermal loading between the PowIRstage® ICs, preventing the overheating of each individual PowIRstage®, resulting in longer lifespan and better reliability.

Server Level Chokes
AORUS X299 series motherboards feature Server Level Chokes:

  • Server level reliability
  • High current capacity
  • New design reduces heat created by power loss and provides efficient power delivery to CPU VRM area

Turbo B-Clock
Built-in Advanced Performance Tuning IC
Turbo B-Clock Tuning IC in the X299 series motherboards enable overclockers to have the ability to change their BCLK frequency to a desired value of their choice. With the new linear range adjustment option of the Tuning IC, ranges from 90MHz to 500MHz are now possible, so that overclockers are not limited to the 5% ranges of traditional straps.
*Turbo B-Clock overclocking range may vary according to CPU capabilities.

Immersive VR Gaming Experiencesfeature

Good VR requires more performance than Full HD graphics for a steady 90FPS or greater. Only Gaming PCs can provide the best VR experiences due to the requirements of high end Graphics, Multi Core CPU Processing Power and DDR4 RAM.

Recommended minimums for a VR Gaming PC with this motherboard:

  • CPU: Intel® X-Series Socket LGA 2066 Processor
  • Memory: 8GB RAM or greater
  • Graphics Card: NVIDIA GTX 1060 / AMD RX 480 or greater
  • OS: Windows® 10 64-bit

To create a seamless VR experience AORUS Motherboards offer the best features to make your virtual reality feel like your actual reality. With technologies such as NVMe support via M.2 or U.2 and a one piece metal shielding to brace for heavier discrete graphics cards it's obvious that AORUS has the tools you need to start your journey in VR. To set the mood AORUS Motherboards include RGB Fusion to put you in the center of action.

Dual Ultra-Fast NVMe PCIe Gen3 x4 M.2 Slots
With two NVMe PCIe Gen3 x4 M.2 connectors onboard, AORUS brings to the user PCI-Express connectivity for SSD devices. Delivering up to 32 Gb/s data transfer speed per connector, the dual M.2 provides an ideal storage solution as it also supports RAID modes.


Support for DDR4 XMP Up to 4333MHz and Beyond
AORUS is offering a tested and proven platform that ensures proper compatibility with profiles up to 4333MHz and beyond. All users need to do to attain this performance boost is to ensure that their memory module is XMP capable and that the XMP function is activated and enabled on their AORUS motherboard.

What is XMP?
DDR4 memory modules are available at a stock frequency of 2,133MHz, but as frequency tweaking requires a considerable amount of effort and knowledge, memory vendors encode XMP profiles which can automatically modify the timings of the supported memory modules to work with your CPU and to achieve increased performance.
* XMP Profile support may vary depending on memory modules used.

Broad DDR4 Compatibility with Support List of 1000+ DDR4 Validated!
AORUS partners very closely with memory vendors from around the world to ensure that modules offered by popular memory brands are compatible with AORUS Motherboards. AORUS has verified over 1000+ different modules to ensure performance in a AORUS built system.
