ASUS Prime X299-A II Intel ATX Motherboard, LGA 2066 for Intel Core X-series processors, with AI Overclocking, 12 IR3555 power stages, DDR4 4266 MHz, Triple M.2, USB 3.2 Gen 2 Type-C and Aura Sync RGB lighting | 90MB11F0-M0EAY0

The Prime X299-A II is the refined successor in the X299 lineup, specifically updated to provide the power stability and connectivity required for the 10th Generation Intel Core X-Series (Cascade Lake-X). While it remains backward compatible with 7th and 9th Gen chips, its thermal and power architecture is fine-tuned for the high wattage of processors like the i9-10920X and i9-10940X, ensuring they can maintain peak turbo frequencies during heavy rendering or encoding tasks.

Robust Power and Cooling Solution
Workstation CPUs demand clean, consistent power. The Prime X299-A II features 12 IR3555 power stages, ProCool II connectors, and high-quality alloy chokes. To keep the VRMs cool, it utilizes a massive heatsink with a high-surface-area fin design connected by a heatpipe. For storage, the board includes Triple M.2 slots, all of which sit under dedicated heatsinks to prevent NVMe thermal throttling during large file transfers.

Next-Gen Storage and Connectivity
Take advantage of enterprise-grade storage with Intel VROC (Virtual RAID on CPU) support, allowing you to use CPU PCIe lanes to create bootable RAID arrays. Connectivity is handled by a high-speed Intel Gigabit LAN and a rear I/O packed with USB 3.2 Gen 2 ports (10Gbps). The board also features a front-panel USB 3.2 Gen 2 connector for modern chassis compatibility and a Thunderbolt 3 header for add-on card support.
 

Personalized Aesthetics with Aura Sync
While the Prime series focuses on professional aesthetics with its clean white-and-silver theme, it doesn't lack personalization. ASUS Aura Sync offers full RGB lighting control with a variety of functional presets for built-in LEDs and strips connected to the onboard RGB headers. This allows the motherboard to perfectly match the lighting of your entire ecosystem, from your RAM to your GPU.
 

Why the Prime X299-A II Stands Out
Optimized for 10th Gen X-Series: Enhanced power delivery for i9-10920X/10940X and beyond.

AI Overclocking: Automatically profiles your CPU and cooling to find the optimal configuration.

Triple M.2: High-speed storage flexibility with integrated thermal management.

8-Slot Quad-Channel DDR4: Supports up to 256GB of memory for massive multitasking.
