The MSI MAG B850M MORTAR WIFI is a Micro-ATX motherboard for PC builders using an AMD Ryzen 9000, 8000 or 7000 series desktop processor. Its compact form factor suits gaming and general purpose builds where space is limited but fast networking and modern storage are priorities.

The AMD B850 chipset and AM5 socket provide the platform for supported Ryzen processors, while four DDR5 memory slots support dual-channel memory. For fast storage, it has three M.2 connectors, including two PCIe 5.0 x4 slots, alongside four SATA ports. Built-in Wi-Fi 7, Bluetooth 5.4 and 5G LAN offer wired and wireless network options without requiring a separate network card. A rear USB Type-C port supports transfer speeds up to 20Gbps.
