MSI MAG B660 Tomahawk Wifi DDR4 Intel Motherboard

The MSI MAG B660 Tomahawk WiFi DDR4 is an ATX-form-factor motherboard built on Intel's B660 chipset and designed for the LGA1700 socket. It supports 12th Generation Intel Core, Pentium Gold, and Celeron processors, making it a capable foundation for a wide range of desktop builds targeting performance and connectivity. Memory flexibility is a strong point of this board. Four DDR4 slots accommodate up to 128 GB of non-ECC, unbuffered RAM in dual-channel configuration. JEDEC-standard speeds of 2133, 2666, and 3200 MHz are natively supported, while XMP profiles allow overclocking up to 4800+ MHz in a single-rank, single-DIMM-per-channel arrangement. Storage options are extensive. Three M.2 Key-M slots handle high-speed NVMe SSDs — the CPU-attached M2_1 slot and chipset M2_2 slot both run at PCIe 4.0 x4, while M2_3 operates at PCIe 4.0 x2. Each M.2 slot is covered by MSI's M.2 Shield Frozr thermal solution to reduce throttling under sustained loads. Six SATA 6 Gb/s ports round out storage connectivity, and the board supports RAID 0, 1, 5, and 10 for SATA drives, plus RAID 0, 1, and 5 for NVMe devices. Networking is handled by a Realtek RTL8125B-CG 2.5 Gbps wired LAN controller alongside an Intel Wi-Fi 6 module (802.11 a/b/g/n/ac/ax) pre-installed in the M.2 Key-E slot. The wireless solution supports MU-MIMO transmit and receive, dual-band operation across 2.4 GHz and 5 GHz, speeds up to 2.4 Gbps, and Bluetooth 5.2. Audio is powered by a Realtek ALC1220P codec delivering 7.1-channel high-definition output with S/PDIF optical output on the rear panel. Display outputs include one HDMI 2.1 port (up to 4K 60 Hz with HDR) and one DisplayPort 1.4 with HBR3 (up to 4K 60 Hz), available when using a processor with integrated graphics. USB connectivity is comprehensive: a USB 3.2 Gen 2x2 Type-C port (20 Gbps) sits on the rear panel alongside four USB 3.2 Gen 2 Type-A ports (10 Gbps) and four USB 2.0 Type-A ports. Additional headers support two USB 3.2 Gen 1 (5 Gbps) and four USB 2.0 ports internally. RGB and addressable RGB headers (two 4-pin RGB and two 3-pin RAINBOW connectors) enable lighting customisation via MSI's Mystic Light ecosystem. Four EZ Debug LEDs assist with POST troubleshooting.
