Description

MSI MAG B850M MORTAR WIFI AM5 mATX Motherboard

The MSI MAG B850M MORTAR WIFI AM5 mATX Motherboard is a high-performance MSI motherboard built on the advanced AMD B850 chipset, designed for users who want to fully leverage AMD Ryzen 9000, 8000, and 7000 Series Desktop Processors with the AM5 socket. It supports up to 256GB of DDR5 memory across four dual-latch DIMM slots, achieving speeds of up to 8200+ MT/s (OC) depending on the CPU and configuration. With support for AMD EXPO, dual-channel architecture, JEDEC and AMD POR speeds, non-ECC UDIMMs, and CUDIMM clock driver bypass mode, it offers maximum compatibility and overclocking flexibility.

Designed for enthusiasts, the MSI MAG B850M MORTAR WIFI features a robust 12+2+1 Duet Rail Power System, dual 8-pin CPU power connectors, Core Boost, and Memory Boost technologies, reinforced by an 8-layer 2oz thickened copper PCB to enhance power delivery, signal integrity, and thermal performance. Expansion and storage are well-supported with one PCIe 5.0 x16 slot, one PCIe 4.0 x4 slot, and three M.2 slots—two supporting PCIe 5.0 x4 (for Ryzen 9000/7000 CPUs) and one PCIe 4.0 x2 via the chipset—along with four SATA 6Gbps ports. RAID support includes RAID 0/1/10 for SATA and RAID 0/1/5 for M.2 NVMe drives, with RAID 5 available exclusively for Ryzen 9000 processors.

Thermal management is handled by MSI’s Frozr Guard design, featuring extended heatsinks, high-performance 7W/mK thermal pads, choke cooling, and EZ M.2 Shield Frozr II to ensure optimal SSD performance. Connectivity is next-generation with onboard Wi-Fi 7, Bluetooth 5.4, and Realtek 8126-VB 5G LAN for fast, stable networking. Extensive USB connectivity includes four USB 2.0 front ports, two USB 5Gbps Type-A front, four USB 5Gbps Type-A rear, three USB 10Gbps Type-A rear, 10Gbps Type-C ports on both front and rear, and a 20Gbps USB Type-C port on the rear I/O panel.

For integrated graphics, an HDMI 2.1 FRL port supports up to 8K resolution at 60Hz depending on the APU. Audio is powered by the Realtek ALC4080 codec with Audio Boost 5, delivering 7.1-channel HD sound, 32-bit/384kHz playback, and S/PDIF output for a studio-grade audio experience. Internal headers support fans, RGB lighting (3x JARGB_V2, 1x JRGB), front panel I/O, TPM 2.0, and more. MSI’s EZ DIY features, including EZ PCIe Release, EZ M.2 Clip II, and EZ Antenna, simplify building and upgrading, while EZ Debug LEDs and EZ Memory Detection LED make troubleshooting easier.

With its compact 243.84mm x 243.84mm mATX form factor, the MSI MAG B850M MORTAR WIFI AM5 mATX Motherboard combines top-tier performance, overclocking potential, advanced connectivity, and user-friendly features, making it one of the most powerful and future-ready MSI AM5 motherboards.
