One of MSI's most balanced mid-range gaming motherboards based on the 2020 AMD B550 chipset. It features small overall dimensions (microATX format), support for high-frequency DDR4 RAM modules (up to 4400 MHz) and an impressive maximum installed RAM volume (up to 128 GB). It is a compact and well-equipped motherboard from the MSI Arsenal Gaming family that fully supports AMD Ryzen 3000 processors with Matisse/Matisse Refresh cores (7nm) and Ryzen 4000 APUs (Renoir core, 7nm).
It differs from its predecessor board (MSI B450M MORTAR) by supporting the PCI-E Gen 4.0 system interface, which allows you to double the data transfer speed with high-speed NVMe SSDs and the latest gaming graphics cards. The MSI MAG B550M MORTAR motherboard is positioned as a solid foundation for building multifunctional home PCs, mid/high-end gaming configurations and workstations. Equipped with four DIMM slots. In addition to two fast NVMe SSDs (one with PCI-E Gen 4.0), it is capable of handling four SATA3 drives. The RTL8125B (2.5 Gbps) controller will help to organize ultra-fast traffic transmission in the LAN network. Audio output is provided by the Realtek ALC1200 8-channel HDA codec with optical output.
