MSI MAG B550 Torpedo DDR4 AMD Motherboard

The MSI MAG B550 Torpedo is a full-size ATX motherboard built on the AMD B550 chipset, designed to support AMD Ryzen 5000 Series, Ryzen 4000 G-Series, and Ryzen 3000 Series desktop processors via the AM4 socket. Note that AMD Ryzen 5 3400G and Ryzen 3 3200G are not compatible with this board. For memory, the board features four DDR4 DIMM slots supporting up to 128 GB in dual-channel configuration. Native JEDEC speeds range from 1866 MHz to 3200 MHz, while the A-XMP overclocking profile pushes supported speeds beyond 4866 MHz depending on DIMM population and rank configuration. Storage is handled by six SATA 6 Gb/s ports and two M.2 Key-M slots. The primary M.2 slot (M2_1) draws bandwidth directly from the AMD processor and supports both PCIe 4.0/3.0 x4 and SATA modes, accommodating 2242 through 22110 form factors. The secondary M.2 slot (M2_2) is driven by the B550 chipset and supports PCIe 3.0 x4 for up to 2280 devices. RAID 0, 1, and 10 are available across SATA drives, while M.2 NVMe drives support RAID 0 and RAID 1. The expansion slot layout includes one PCIe 4.0/3.0 x16 primary slot, one PCIe 3.0 x16 slot operating at x4 electrical speed, and two PCIe 3.0 x1 slots. Two-Way AMD CrossFire multi-GPU configurations are supported via the Steel Armor-reinforced PCIe slots. Connectivity on the rear I/O panel includes a Realtek RTL8125B 2.5 Gbps wired LAN controller, USB 3.2 Gen 2 10 Gbps Type-A and Type-C ports, USB 3.2 Gen 1 5 Gbps Type-A ports, USB 2.0 ports, HDMI 1.4 and DisplayPort video outputs (for processors with integrated graphics), Optical S/PDIF out, HD Audio jacks, PS/2 combo port, and a Flash BIOS Button for firmware recovery without a CPU installed. Internal USB headers add further front-panel USB Type-C (Gen 1), additional Gen 1 Type-A, and USB 2.0 connectivity. Audio is powered by the Realtek ALC1200 codec delivering 7.1-channel HD audio with S/PDIF output support. The board ships with a pre-installed I/O shield for easier installation and improved EMI protection. RGB and addressable lighting headers include two 4-pin RGB connectors and two 3-pin ARGB (Rainbow) connectors, along with six 4-pin system fan headers, one CPU fan header, and one water-pump fan header. The power delivery system uses a 10+2+1 Duet Rail phase design with digital PWM, supported by an extended heatsink incorporating a 7 W/mK rated choke thermal pad and a 2 oz thickened copper PCB layer for sustained thermal performance under load. An M.2 Shield Frozr heatsink covers the primary M.2 slot to manage NVMe drive temperatures. Key Verified Specifications: - Chipset: AMD B550 - Socket: AM4 - Form Factor: ATX, 12 in. x 9.6 in.
