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 PCIe 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.

Digital Power Design PRIME B850M-A WIFI features an 8+2+1 phase power design with discrete MOSFETs, ensuring efficient and s... moretable power delivery for AMD processors plus steady performance for day-to-day use. Six-layer PCB design The multi-layered printed circuit board design quickly dissipates heat around the voltage regulators to improve overall system stability and provide the CPU with more overclocking headroom. Digi+ VRM control The Digi+ voltage-regulator module (VRM) delivers real-time control over voltage droop, automatically switching frequency and power-efficiency settings. Enhanced DDR5 performance Comprehensive memory tuning options are the cornerstone of PRIME motherboards. The PRIME B850M-A WIFI maximizes the potential of your DDR5 modules, from entry-level to extreme-speed kits. For entry-level modules without EXPO™ support, ASUS Enhanced Memory Profile (AEMP) automatically detects memory chips and provides optimized profiles for enhanced performance. For those looking to surpass stock DDR5 speeds, the PRIME B850M-A WIFI offers extensive AMD Extended Profiles for Overclocking (EXPO™) support and a wide array of UEFI settings for further performance tweaks. Three M.2 slots (up to 128 Gbps) PRIME B850M-A WIFI offers a total of three M.2 slots, including one that supports data-transfer speeds of up to 128 Gbps via PCIe 5.0, and two that support PCIe 4.0. This enables quicker boot-up and app load times with OS or application drives. Cooler by design The PRIME B850M-A WIFI motherboard is engineered with multiple onboard heatsinks and an array of hybrid fan headers to help ensure your rig stays cool and stable under intense workloads. ASUS Fan Xpert 2+ ASUS Fan Xpert 2+ software provides comprehensive control over fans. An Auto-Tuning mode intelligently configures all parameters with a single click. There’s also an Extreme Quiet mode that reduces chassis fan speeds to below the default minimum to keep your system whisper-quiet when performing light tasks. Fans can also be controlled via the UEFI BIOS. Empowering connections This motherboard offers a versatile range of connectivity, including support for WiFi 6E, PCIe 5.0 slot and an arsenal of USB ports which includes Type-C® connections. WiFi 6E Built-in WiFi 6E technology takes advantage of the newly available radio spectrum in the 6 GHz band. With triple the bandwidth of the 2.4/5/6 GHz band, WiFi 6E delivers ultrafast wireless networking speeds with improved capacity and better performance in dense wireless environments. Realtek 2.5 Gb Ethernet Realtek 2.5 Gb Ethernet reduces CPU overhead and offers exceptionally high TCP and UDP throughput for faster, smoother data transfers. Front USB 5Gbps Type-C® This motherboard features a USB 5Gbps Type-C® front panel connector for speedy data transfers of up to 5Gbps.
