ASUS Prime B650M-A WiFi II

The Prime B650M-A WiFi II is the refreshed micro-ATX entry in ASUS's Prime B650 lineup, giving budget builders PCIe 5.0 M.2 support on the primary slot and built-in Wi-Fi 6 in a compact footprint.

ASUS does not publish an exact VRM phase count for this board, but it is rated for Ryzen 9000 non-X3D chips at stock clocks, consistent with other entry-tier Prime boards. Four DDR5 DIMM slots support up to 192GB total capacity, with AMD EXPO enabling overclocked speeds up to 7600+ MT/s. Expansion includes a primary PCIe 4.0 x16 slot (x16 mode on Ryzen 9000/7000) and two PCIe 4.0 x16 slots running at x1 from the chipset. Storage covers two M.2 slots: the primary supports PCIe 5.0 x4 on Ryzen 9000/7000 series, and the secondary runs PCIe 4.0 x4. A Realtek 2.5Gb Ethernet controller handles wired networking, paired with Wi-Fi 6 (802.11ax) and Bluetooth 5.2. Audio uses a Realtek 7.1 surround codec supporting 24-bit/192kHz playback. Against the Gigabyte B650M AORUS Elite AX in this batch, the Prime B650M-A WiFi II includes a PCIe 5.0 M.2 slot on its primary socket, which the Gigabyte board's PCIe 4.0-only M.2 slots don't match, making it a stronger pick for future Gen5 SSD upgrades.
