Overview
The ASUS B850M AYW Gaming WiFi 6 is a Micro-ATX motherboard built on the AMD B850 chipset with an AM5 socket, designed to support AMD Ryzen 9000, 8000, and 7000 Series desktop processors. It targets PC builders who want a compact, capable platform that pairs stable power delivery with modern connectivity for gaming and demanding workloads. Power is delivered through an 8+2+1 phase digital design using discrete MOSFETs, keeping CPU voltages steady whether you are running everyday applications or sustained workloads. Two DDR5 memory slots support dual-channel configurations up to 128 GB, with speeds rated beyond 9600 MT/s when using EXPO-certified kits. For standard modules without EXPO profiles, ASUS Enhanced Memory Profile (AEMP) technology automatically detects chip characteristics and selects optimised timings to extract additional performance. Storage flexibility is handled by two M.2 Key-M slots: one operates at up to 128 Gbps via PCIe 5.0 x4, and a second runs at up to 64 Gbps via PCIe 4.0 x4. Four SATA 6 Gb/s ports accommodate additional drives. The reinforced PCIe 5.0 x16 SafeSlot accepts discrete graphics cards when paired with Ryzen 9000 or 7000 Series CPUs, running at full x16 electrical bandwidth. Connectivity on the rear I/O panel includes Wi-Fi 6, Bluetooth 5.3 via an integrated module, a Realtek 2.5 Gb Ethernet port, two USB 10 Gbps Type-A ports, two USB 5 Gbps Type-A ports, four USB 2.0 Type-A ports, a single HDMI output, three analogue audio jacks, and a dedicated BIOS FlashBack button for tool-free firmware updates. Internally, the board adds a USB 5 Gbps Type-C connector, two additional USB 5 Gbps headers, two USB 2.0 headers, and three Addressable RGB Gen 2 headers for lighting control. Builder-oriented features include Q-Latch screwless M.2 retention, Q-LED POST indicators for CPU, memory, GPU, and storage, and a pre-mounted I/O shield. BIOS FlashBack allows firmware updates without a functioning CPU or memory module inserted.
