ASUS PRIME B840M-A WIFI Ultimate AI-Ready Micro-ATX Motherboard
Next-Gen Performance for Gamers & Creators
Built for AMD Ryzen™ 9000, 8000, and 7000 Series processors, the ASUS PRIME B840M-A WIFI offers top-tier performance in a compact micro-ATX form. This motherboard embraces the power of the AMD B840 chipset and introduces cutting-edge support for DDR5 memory, PCIe 4.0 lanes, and high-speed M.2 storage. Whether you’re gaming, creating content, or multitasking, its advanced AI PC readiness ensures your rig delivers optimized efficiency across all applications.
Smarter Power & Cooling with AI Solutions
The motherboard features an 8+2+1 power phase design, Digi+ VRM control, and a 6-layer PCB to ensure stability under demanding conditions. ASUS AI Advisor offers step-by-step optimization while Fan Xpert 2+ handles thermals with precision. Comprehensive cooling support includes hybrid fan headers and AIO pump support, making this board ideal for high-performance builds. BIOS FlashBackâ„¢ allows for quick and easy updates, even without a CPU or RAM installed.
Future-Proof Connectivity & Personalization
With Wi-Fi 6E and 2.5Gb LAN, you’re set for low-latency gaming and ultra-fast data transfers. USB 10Gbps and 5Gbps ports (including front panel Type-C®) provide exceptional peripheral bandwidth. Aura Sync RGB lighting and Addressable Gen2 headers enable full customization, while Q-Antenna and pre-mounted I/O shields make building easy. ASUS Armoury Crate and GlideX round out the experience with unified control over lighting, system settings, and screen sharing.
