MSI MSI MAG B850M MORTAR WIFI Motherboard - AMD B850 Socket AM5 - Micro ATX

MSI MAG B850M MORTAR WIFI Motherboard brings modern Socket AM5 performance to a compact micro-ATX design for desktop builders and gamers.

Built on the AMD B850 chipset, the MSI MAG B850M MORTAR WIFI supports AMD Ryzen 7000, 8000 and 9000 Series processors in Socket AM5, offering broad compatibility for current and future CPU upgrades.

This micro-ATX board supports DDR5 memory in four DIMM slots with dual-channel operation and a maximum capacity of 256 GB, supporting memory speeds up to 8200 MHz for demanding multitasking and content creation workloads.

Storage options are generous for a small form factor, with three M.2 slots (two PCIe Gen5-capable) and four SATA III ports, enabling up to seven drives and RAID 0, 1 and 10 configurations for speed or redundancy.

Connectivity is robust, featuring Wi‑Fi 7 (802.11be) and Bluetooth 5.4 on board, a 5 Gigabit Ethernet RJ-45 port, multiple USB ports including USB 3.2 Gen2 Type-A and Type-C, and an HDMI 2.1 output for integrated display options when using APUs that provide graphics.

Thermal and RGB controls are well covered with two CPU fan headers, a dedicated water pump header, and three RGB LED pin headers, while the Realtek ALC4080 codec delivers 7.1-channel audio for immersive sound.

Typical use cases include compact gaming builds, streaming and content-creation PCs that need fast storage and networking, and upgrade paths for users moving to the latest Ryzen processors. The micro-ATX footprint (243.8 x 243.8 mm) makes it ideal for smaller cases without sacrificing features.
