MSI Pro B660M-A Wifi DDR4 Intel Motherboard

The MSI Pro B660M-A WiFi DDR4 is a Micro-ATX motherboard designed around Intel’s B660 chipset and the LGA1700 socket, offering broad compatibility with 12th Generation Intel Core, Pentium Gold, and Celeron processors. Its compact 9.6 × 9.6-inch footprint makes it a practical choice for space-conscious builds without sacrificing connectivity or expansion options. On the memory side, four DDR4 slots accept up to 128 GB of non-ECC unbuffered RAM. Standard JEDEC profiles run at 2133, 2666, and 3200 MHz, while Intel XMP support unlocks overclocked speeds up to 4800+ MHz in a single-rank, single-DIMM configuration. Dual-channel operation is supported across all populated configurations. Storage flexibility is a highlight. Two M.2 Key-M slots both support PCIe 4.0 x4 speeds — the primary slot fed by the CPU and the secondary by the B660 chipset, which also adds SATA 6 Gb/s compatibility. Both slots are covered by MSI’s M.2 Shield Frozr heatsink to help maintain sustained SSD performance. Four additional SATA 6 Gb/s ports and RAID 0/1/5/10 support round out the storage picture. Connectivity is a genuine strength. Wired networking is handled by a Realtek RTL8125BG 2.5 Gbps LAN controller managed through MSI’s LAN Manager software. Wireless is provided by an Intel Wi-Fi 6 (802.11ax) module pre-installed in the Key-E M.2 slot, supporting MU-MIMO TX/RX across 2.4 GHz and 5 GHz (160 MHz) bands up to 2.4 Gbps, alongside Bluetooth 5.2. Display output is handled by two HDMI 2.1 ports (4K 60 Hz with HDR) and two DisplayPort 1.4 ports (HBR3, 4K 60 Hz), useful when pairing with Intel’s integrated graphics. The rear I/O also includes USB 3.2 Gen 2 10 Gbps Type-A and USB 3.2 Gen 1 5 Gbps Type-A ports. Internally, headers cover USB 3.2 Gen 1 Type-C, Type-A, and four USB 2.0 ports. Audio is delivered through a Realtek ALC897 codec supporting 7.1-channel high-definition audio output. RGB enthusiasts will find one 4-pin RGB and two 3-pin ARGB headers, plus four EZ Debug LEDs for quick fault diagnosis. Fan management includes a dedicated 4-pin water-pump header, one CPU fan header, and two system fan headers.
