The MSI B550 GAMING GEN3 is an ATX motherboard designed for the AMD AM4 socket, providing a foundation for PC builds using Ryzen 5000, 4000 G-Series, and 3000 Series processors. It is constructed around the AMD B550 chipset and utilizes a standard power configuration with 24-pin ATX and 8-pin EPS connectors for CPU power delivery. The ATX form factor allows for installation in a wide range of mid-tower and full-tower cases, providing ample space for components and cooling hardware.
This motherboard features four DDR4 DIMM slots that support up to 128GB of dual-channel memory, with overclocked speeds reaching up to 4400 MHz. For storage, it is equipped with one M.2 slot that operates on a PCIe 3.0 x4 interface for high-speed SSDs, alongside six SATA 6Gb/s ports for conventional hard drives and SSDs. The platform also supports RAID 0, 1, and 10 configurations for data redundancy or performance enhancement across multiple drives.
Expansion capabilities include two full-length PCIe x16 slots and four PCIe x1 slots for adding graphics cards and other peripherals. The rear I/O panel offers a selection of USB ports, including USB 3.2 Gen 1 and Gen 2 Type-A. Network connectivity is handled by a 1GbE LAN port for a wired connection. Onboard audio is powered by the Realtek ALC897 codec, and the board includes internal headers for chassis fans, front panel USB, and a single RGB lighting strip.
