MSI MAG B550 Tomahawk MAX Wifi DDR4 AMD Motherboard

The MSI MAG B550 Tomahawk MAX WiFi is an ATX form-factor motherboard built on the AMD B550 chipset for the AM4 socket. It is designed to support AMD Ryzen 5000 Series, 5000 G-Series, 4000 G-Series, and 3000 Series desktop processors, making it a capable foundation for a wide range of AMD-platform builds. Memory flexibility is a highlight: four DDR4 DIMM slots accommodate up to 128 GB of system RAM. JEDEC-standard speeds range from 1866 MHz to 3200 MHz, while MSI's A-XMP overclocking profiles push frequencies as high as 5100 MHz (1DPC 1R configuration). Both ECC and non-ECC unbuffered UDIMMs are supported, and the dual-channel architecture keeps data throughput efficient under demanding workloads. For storage, the board provides two M.2 Key-M slots alongside six SATA 6 Gb/s ports. The primary M.2 slot (M2_1), driven directly by the processor, supports PCIe 4.0/3.0 x4 and SATA, and accepts drives up to 22110 mm. The secondary slot (M2_2) from the B550 chipset runs PCIe 3.0 x4 and accepts drives up to 2280 mm. RAID 0, 1, and 10 are supported for SATA devices; RAID 0 and 1 for M.2 NVMe drives. Both M.2 slots are fitted with MSI M.2 Shield Frozr heatsinks to help manage SSD operating temperatures. Expansion slots include one PCIe 4.0/3.0 x16 slot with Steel Armor reinforcement for the primary graphics card, one PCIe 3.0 x16 slot running at x4 speed, and two PCIe 3.0 x1 slots. AMD CrossFire multi-GPU configurations are supported. Connectivity is comprehensive. Wired networking is handled by a Realtek RTL8125B 2.5 Gbps LAN controller. Wireless is provided by an AMD Wi-Fi 6E module (pre-installed in the M.2 Key-E slot) supporting 802.11 a/b/g/n/ac/ax across 2.4 GHz, 5 GHz, and 6 GHz bands at up to 2.4 Gbps with MU-MIMO TX/RX, and Bluetooth 5.2. USB ports on the rear panel include two USB 3.2 Gen 2 10 Gbps ports (one Type-C, one Type-A), two USB 3.2 Gen 1 5 Gbps Type-A ports, and two USB 2.0 Type-A ports. Display outputs for APU-equipped processors include one HDMI 2.1 (up to 4K@60 Hz) and one DisplayPort 1.4 (up to 4K@60 Hz). Audio is delivered via a Realtek ALC897 codec with 7.1-channel HD audio and optical S/PDIF output. The board also includes a Flash BIOS button for BIOS recovery without a CPU installed. RGB and system management headers include two 4-pin RGB LED connectors, two 3-pin RAINBOW LED connectors, six 4-pin system fan connectors, one 4-pin CPU fan connector, one 4-pin water-pump fan connector, a TPM module connector, and a chassis intrusion connector.
