The MSI MAG B850M MORTAR WIFI is a powerful MSI motherboard based on the advanced AMD B850 chipset, designed specifically for customers who want to take advantage of the power of AMD Ryzen 9000, 8000, and 7000 Series Desktop Processors with the AM5 socket. The MSI MAG B850M MORTAR WIFI Motherboard supports up to 256GB of DDR5 memory over four dual-latch DIMM slots and offers excellent memory speeds of up to 8200+ MT/s (OC) depending on CPU and setup. It supports AMD EXPO, dual-channel architecture, JEDEC and AMD POR speeds, non-ECC UDIMMs, and CUDIMM clock driver bypass mode, providing maximum compatibility and overclocking freedom. 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 high-speed storage capabilities on the MSI MAG B850M MORTAR WIFI mATX Motherboard include one PCIe 5.0 x16 slot, one PCIe 4.0 x4 slot, and three M.2 slots—two of which support PCIe 5.0 x4 (when using Ryzen 9000/7000 CPUs) and one PCIe 4.0 x2 via the chipset, in addition to four SATA 6Gbps ports. RAID functionality supports 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. Thermally, the MSI MAG B850M MORTAR WIFI AM5 mATX Motherboard incorporates MSI’s Frozr Guard thermal design, which includes extended heatsinks, high-performance thermal pads (7W/mK), choke cooling, and EZ M.2 Shield Frozr II for optimal M.2 SSD performance and installation ease. Connectivity is next-gen with onboard Wi-Fi 7, Bluetooth 5.4, and Realtek 8126-VB 5G LAN, delivering blazing-fast network speeds for gaming, streaming, and professional workloads. The MSI MAG B850M MORTAR WIFI Motherboard also features extensive USB connectivity: four USB 2.0 front ports, two USB 5Gbps Type-A front, four USB 5Gbps Type-A rear, three USB 10Gbps Type-A rear, a 10Gbps Type-C port on both front and rear panels, and a blazing-fast 20Gbps USB Type-C port on the rear I/O. For integrated graphics users, an HDMI 2.1 FRL port supports up to 8K resolution at 60Hz, depending on the installed APU. Audio is powered by the Realtek ALC4080 Codec, supporting 7.1-channel HD audio, 32-bit/384kHz playback, and S/PDIF output, enhanced by Audio Boost 5 for a studio-grade sound experience. The board has a number of internal connections and headers for 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, make constructing and upgrading easier than ever. Troubleshooting is made easier with EZ Debug LEDs and an EZ Memory Detection LED.
