Verdict

The ASUS Prime B650M-A AX is a feature-rich Micro-ATX motherboard designed for the AMD AM5 socket, supporting Ryzen 7000, 8000, and 9000 series processors with up to a 170W TDP. It features four DDR5 DIMM slots for high-speed memory overclocking via AMD EXPO, a primary M.2 slot supporting PCIe 5.0 x4 speeds, and eight SATA 6Gb/s ports for extensive storage. Key pros include high-speed connectivity with Wi-Fi 6, 2.5Gb Ethernet, and USB 3.2 Gen 2 ports, alongside robust cooling via VRM heatsinks and Fan Xpert 2+ software. On the downside, some users have reported issues with coil whine, and the secondary M.2 slots are limited to PCIe 4.0 speeds.
