Features:

The Prime X299-A II caters to users with serious pursuits: 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.

Get the most out of all your cores
Intel 's high-end desktop platform raises the stakes with updated Intel Core X-Series Processors that boast cores, cache, and bandwidth. The Prime X299-A II is ready for the additional processing power that plows through CPU-intensive tasks, and the extra bandwidth allows you to add more GPUs and NVMe SSDs to accelerate a wide range of work.

Robust Power Design
The LGA 2066 socket is compatible with 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.
ProCool II Connectors
PowIRstage MOSFETS
Microfine Alloy choke
ProCool II connector
ProCool II connectors ensure a snug and reliable connection to the EPS 12V power lines. The second-generation features upgrades of metal amour and solid pins for better heat dissipation, as well as a warning LED-display with a BIOS POST message to indicate an improper connection.

Cool to the core
Effective cooling is extremely important, even at stock speeds. That is why the Prime 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.

M.2 Heatsinks
Two M.2 slots are covered by heatsinks to combat temperature-induced throttling that can affect performance during heavy, sustained storage loads.

Tune it your way
Comprehensive controls form the foundation of the ASUS Prime series. The Prime X299-A II packs flexible tools to tune every aspect of your system to deliver the performance that you desire.

AI Overclocking
ASUS 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.

CPU Potential
A proprietary algorithm evaluates the capabilities of your CPU

Cooling Capability
Onboard intelligence watches system vitals such as temperature, fan speed, and power draw to gauge cooling performance

Little things make a big difference
We pay careful attention to all the little details that improve your overall experience, from integrating a flashing utility directly into the UEFI to simplifying firmware updates or displaying your system vital signs. Prime X299-A II provides the tools you need to personalize your build and stay on top of things.

Set up without slip-ups
Form meets function in the pre-mounted I/O shield that we pioneered with the ROG series. Now available on Prime X299-A II, this feature streamlines the installation process for budding builders and savvy enthusiasts alike.

Intel Optane memory ready
Intel Optane is a revolutionary non-volatile memory technology supported by Prime X299-A II. Intel Optane memory modules accelerate attached storage to reduce boot and load times, so everything feels faster and more responsive.

Intel X299 chipset
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 1 ports, 8 SATA 6 Gbps ports and up to 32 Gbps M.2 support for faster data retrieval.
