  • Strong 14-phase power delivery (VRM) capable of handling high-end processors like the i9-12900K
  • Excellent thermal management with large, heavy heatsinks for VRMs and M.2 drives
  • Modern connectivity including Wi-Fi 6, 2.5G LAN, and a 20Gbps USB 3.2 Gen 2x2 Type-C port
  • User-friendly design features like a pre-installed I/O shield and quick-release M.2 clips
  • Provides a cost-effective path by supporting more affordable DDR4 memory instead of DDR5

What customers don't like about MSI MAG B660M Mortar Max WiFi DDR4

  • Uses the older ALC897 audio codec, which some users consider a downgrade from higher-end boards
  • Lacks PCIe 5.0 support, being limited to PCIe 4.0 for both the primary slot and M.2 storage
  • Potential clearance issues; some users noted that using the quick-release M.2 clips can interfere with certain M.2 heatsinks
  • Limited expansion options due to the micro-ATX form factor, specifically having fewer M.2 slots than full ATX boards
  • Initial BIOS versions may require updates for full compatibility with 13th and 14th Gen Intel CPUs

Verdict

The MSI MAG B660M Mortar Max WiFi DDR4 is a premium Micro-ATX motherboard designed for Intel 12th, 13th, and 14th Gen processors on the LGA 1700 socket. It stands out with its unique OC Engine external clock generator that enables BCLK overclocking for non-K CPUs, supported by a robust 12+1+1 Duet Rail Power System with 60A DrMOS. Key specifications include a PCIe 5.0 x16 slot, two PCIe 4.0 M.2 slots with Shield Frozr heatsinks, four DDR4 slots supporting up to 4800+(OC) MHz, 2.5G LAN, and integrated Intel Wi-Fi 6E. Main pros include its exceptional power delivery for high-end CPUs, versatile high-speed connectivity like USB 3.2 Gen 2x2 (20Gbps), and a sleek silver-metallic aesthetic. Notable cons include the use of the budget-oriented Realtek ALC897 audio codec instead of higher-end alternatives and the lack of a third M.2 slot found on some competing boards.
