Reliable, well-balanced, compact micro-ATX motherboard based on the AMD B850 chipset. Equipped with an AMD AM5 processor socket and optimized for the latest Ryzen processors from the 7000, 8000, and 9000 series (socket AM5). Positioned in the mid-price segment, it represents the Asus Prime 2025 series. Although most Prime models are more aligned with office-budget levels, this board's features can provide a reliable foundation for a mid-level gaming or work PC with ample memory, fast storage, and a powerful Ryzen 7 9700X level processor.

The Asus PRIME B850M-A WIFI boasts a solid component base (11 power phases, VRM and PCH heatsinks, quality inductors, and durable capacitors), thoughtful layout, and useful tools for additional system tuning and monitoring. Despite its compact size, the board is equipped with a modern set of interfaces, including a pair of reinforced PCI-E 16x slots, three high-speed M.2 ports (one Gen5, two others Gen4), and four SATA connectors with RAID support. Unlike many miniature motherboards, it features four full-fledged DDR5 memory slots with a maximum frequency of 8000 MHz and EXPO profile support. The device's networking capabilities are handled by a Realtek controller (2.5 Gb/s bandwidth) with support for Wi-Fi 6E and Bluetooth 5.3.
