Verdict

The MSI MAG B650M Mortar WiFi is a robust Micro-ATX motherboard designed for the AMD AM5 socket, supporting Ryzen 9000, 8000, and 7000 series processors. Key specifications include a 12+2+1 phase VRM with 80A Smart Power Stages, four DDR5 DIMM slots supporting speeds up to 7600+ MHz (OC), and dual PCIe 4.0 x16 slots. For storage and connectivity, it features two Lightning Gen4 M.2 slots with Shield Frozr, 2.5G LAN, Wi-Fi 6E, and a rear USB 3.2 Gen 2x2 Type-C port offering 20Gbps speeds. Main pros include its powerful thermal solution with extended heatsinks, high-quality Audio Boost 5, and a pre-installed I/O shield that simplifies building. However, notable cons include the lack of PCIe 5.0 support for either graphics or NVMe storage and its relatively high price point for a B650 Micro-ATX board.

What customers dislike about MSI MAG B650M Mortar?

  • The BIOS interface (Click BIOS 5) is frequently described as dated and 'quirky' compared to competitors
  • Limited to only two M.2 slots, both of which are PCIe 4.0 only (no PCIe 5.0 support)
  • The primary PCIe x16 slot is positioned lower (2nd slot position), which can cause clearance issues for large GPUs in compact cases
  • Awkward placement of the USB 3.0 header at the bottom corner of the board
  • Slower boot times compared to some other B650 motherboards
  • Higher price point compared to entry-level B650 Micro-ATX alternatives
  • Occasional reports of the board shipping with outdated BIOS that requires flashing before it will POST with newer CPUs
