What we like about MSI Pro B850M A

  • Modern connectivity including Wi-Fi 7 and 5G LAN for fast networking
  • Includes a PCIe 5.0 x16 slot for future-proofing graphics cards and Gen5 M.2 support
  • Features a robust 8+2+1 power phase design (60A) suitable for mid-to-high-end Ryzen processors
  • User-friendly DIY features like the EZ M.2 Clip II for tool-free SSD installation
  • Neutral white-silver aesthetic that fits well in both black and white PC builds
  • Good value for a budget-to-midrange AM5 platform motherboard

What we don't like about MSI Pro B850M A

  • Uses the older Realtek ALC897 audio codec, which is considered basic compared to premium boards
  • Limited to two M.2 slots, which may be insufficient for users with extensive storage needs
  • VRM heatsink is functional but lacks advanced heatpipe connections found on higher-tier models
  • Potential driver issues reported with integrated LAN and Wi-Fi on some B850 chipsets
  • Lacks an 'EZ PCIe Release' button, making GPU removal difficult in compact cases with large cards

Verdict

The MSI PRO B850M-A WIFI is a Micro-ATX motherboard designed for the AMD AM5 socket, supporting Ryzen 9000, 8000, and 7000 series processors. Key specifications include a direct 8+2+1 phase power system with 60A Smart Power Stages, four DDR5 slots supporting overclocked speeds up to 8200+ MT/s, and a primary PCIe 5.0 x16 slot. For storage, it features a Lightning Gen 5 M.2 slot alongside a Gen 4 slot, both protected by M.2 Shield Frozr cooling. Modern connectivity is a major highlight, offering Wi-Fi 7, 5G LAN, and a rear I/O with multiple 10Gbps USB Type-A and Type-C ports. Main pros include its future-proof networking, tool-free EZ DIY features like the M.2 Clip II, and robust VRM cooling for productivity tasks. However, some users note the use of the older Realtek ALC897 audio codec as a drawback compared to higher-end gaming alternatives.
