MSI MAG B550M MORTAR
 | Outdated Product One of MSI's most balanced mid-range gaming motherboards based on the 2020 AMD B550 chipset.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 PCIe 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 multifunctio...nal home PCs, mid/high-end gaming configurations and workstations. Equipped with four DIMM slots. In addition to two fast NVMe SSDs (one with PCIe 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. |
