The ASUS PRIME B840M-A WIFI CSM is an Advanced AI PC-ready Micro-ATX motherboard utilizing the AMD AM5 socket to support AMD Ryzen 9000, 8000, and 7000 series desktop processors. Built as part of the ASUS Corporate Stable Model (CSM) program, it includes server-grade remote IT infrastructure monitoring via ASUS Control Center Express alongside a guaranteed 36-month stable lifecycle supply roadmap.
The board features a reliable 8+2+1 digital power phase delivery layout on a 6-layer stable PCB with dedicated VRM and M.2 passive cooling heatsinks. It houses four DDR5 DIMM slots accommodating up to 256GB of system memory with dual-channel overclocked frequencies reaching 7600+ MT/s via AMD EXPO and ASUS AEMP performance tuning. For hardware expansion and heavy data storage, it provides a primary steel-reinforced PCIe 4.0 x16 SafeSlot Core+ expansion slot, three NVMe M.2 storage slots (featuring two high-bandwidth PCIe 4.0 x4 configurations running up to 64 Gbps), and 4 SATA 6Gb/s ports. Next-generation networking and I/O routing are natively driven by an integrated Wi-Fi 6E module, Bluetooth 5.3, and a high-speed Realtek 2.5Gb Ethernet port, heavily augmented with rear USB 10Gbps Type-A interfaces, front/rear USB 5Gbps Type-C support, an effortless toolless Q-Antenna assembly, and a physical hardware BIOS FlashBack system.
