Asus Prime X299-A II Intel X-Series ATX Motherboard

Built For Extreme CPU and GPU Power with AI OverclockingThe Prime X299-A II has been crafted for users who take their computing needs seriously. Those who prefer to put their high-core-count processors to more productive use. This high-end desktop board combines cutting-edge performance with our signature features, including an enhanced VRM tailored for running the CPU performance at stock speeds, intuitive cooling control, next-gen connectivity, and extensive customization.

Please Note: The Intel X299 chipset supports LGA 2066-socket Intel Core X-series processors. It provides improved performance by utilizing serial point-to-point links, allowing increased bandwidth and stability. Additionally, X299 provides a maximum 10 USB 3.2 Gen 2 ports, 8 SATA 6 Gbps ports and 32 Gbps M.2 support for faster data retrieval.

Gain the edge from a more efficient Encore Power DesignThe LGA 2066 socket is compatible with the latest Intel Core X-Series Processors with up to 18 cores, over 44 PCI Express® lanes, and 165-watt thermal design power (TDP). Those specs require serious power, so the Prime X299-A II is equipped with an enhanced power solution that includes 12 power stages that line up neatly along the top edge of the PCB. Prime X299-A II VRM is comprised of 12 IR3555 PowIRstages®, each rated to handle 60 amps and is accompanied by a high-permeability alloy-core choke.

onboard intelligence lets you perform automated overclocking in a single clickASUS AI Overclocking makes automatic tuning faster and smarter than ever before. Available in Windows or directly through the UEFI, it profiles the CPU and cooling to predict the optimal configuration for each individual system. A proprietary algorithm evaluates the capabilities of your CPU whilst watching system vitals such as temperature, fan speed, and power draw to gauge cooling performance.

load up on GPUs to accelerate an increasingly diverse array of workThe X299 platform delivers ample bandwidth on multiple fronts. Its quad-channel memory controller supports up to 256 GB of DDR4 memory across eight slots. With optimised trace layout, the Prime X299-A II can hit memory speeds up to DDR4 4266 MHz or beyond. Fully loaded takes on a new meaning when you have over 44 PCI Express lanes stemming from the CPU. Those lanes can be split in an x16/x16/x8 configuration spanning the board's trio of PCIe x16 slots, allowing you to load up on GPUs to accelerate an increasingly diverse array of work.

Achieve speed with onboard M.2Prime X299-A II allows consolidated cooling control of the entire system, even for the most hardcore rigs. It comes equipped with onboard heatsinks, an array of fan headers, and options for water pump or AIO headers. Two M.2 slots are covered by heatsinks to combat temperature-induced throttling that can affect performance during heavy, sustained storage loads. A reinforced backplate improves the stability of the board, and the included thermal pad efficiently directs heat away from the VRM and other components. Prime X299-A II is equipped with three M.2 slots that are compatible with the latest NVMe SSDs. All slots support longer 110 mm drives, and they can be configured into bootable RAID arrays connected directly to the CPU via Intel VROC technology.

level up your performanceOne click takes care of all that complex tuning. ASUS 5-Way Optimisation makes your PC smart. It dynamically optimises essential aspects of the system, providing overclocking and cooling profiles that are tailored for your rig.

Network-optimisation software for customisable packet prioritisationThe latest Intel I219-V Ethernet has the advantage of reducing CPU overhead and offering exceptionally high TCP and UDP throughput for faster, smoother data transfer. ASUS LANGuard is a hardware-level networking protection that employs signal-coupling technology and premium anti-EMI surface-mounted capacitors to ensure a more reliable connection and better throughput. Turbo LAN with cFosSpeed traffic-shaping technology allows you to configure application priority via an intuitive interface and reduces network lag.

Surround Sound with DTS:X ULTRA Prime X299-A II utilises a unique audio codec designed in close collaboration with Realtek — the Realtek S1220. It also features an unprecedented 120dB signal-to-noise ratio for the stereo line-out and a 113dB SNR for the line-in, providing pristine audio quality. Additionally, a new impedance-sensing circuit automatically adjusts the gain to ensure 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 and supports sound based on channels, scenes, and objects to allow for deeper sonic immersion in enabled content.

ASUS' RGB Software with Addressable Gen 2 RGB headerA 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 and they can all be synced with an ever-growing portfolio of Aura-capable ASUS hardware. The board has dual headers for standard 4-pin RGB strips*, plus two more for the new Addressable Gen 2 RGB strips** and devices.

* The Aura RGB-strip header supports standard 5050 RGB LED strips with a maximum power rating of 3A (12V). For maximum brightness, strip length should not exceed 3m.
** The addressable RGB header supports WS2812B addressable RGB LED strips (5V/Data/Ground), with a max power rating of 3A (5V) and a max of 60 LEDs.
