MSI PRO B660M-A WiFi (LGA1700/Intel B660/mATX/DrMOS VRM/DDR5/Wi-Fi 6) Review
The PRO B660M-A WiFi gives budget LGA1700 builders a DDR5-supporting micro-ATX board for 12th and 13th Gen Intel Core processors, filling the value tier below MSI's MAG and MPG Z690/Z790 boards for buyers who don't need overclocking support.
MSI has not published an exact VRM phase count for this board; it uses DrMOS power stages sufficient for non-K Core i5 and i7 chips at stock clocks, and reviewers note it is not designed for K-series overclocking given the B660 chipset's locked multiplier. Four DDR5 memory slots support up to 192GB total capacity, with 1DPC 1R speeds rated up to 6200+ MHz. Expansion includes two x16 slots (one PCIe 4.0, one PCIe 3.0 running at x4) plus a PCIe 3.0 x1 slot. Storage covers two M.2 slots supporting PCIe 4.0 x4 for NVMe drives. A Realtek RTL8125BG 2.5Gbps LAN controller handles wired networking, paired with Intel Wi-Fi 6 and Bluetooth 5.2. Audio uses a Realtek ALC897 codec with 7.1-channel support. As the only LGA1700 board in this catalog, the PRO B660M-A WiFi serves budget 12th/13th Gen Intel builders directly, offering DDR5 support that its DDR4 sibling variant lacks, at a lower cost than moving to a Z690 or Z790 board for non-overclocking builds.
