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.
