Building with the MAG B850M MORTAR WIFI is a streamlined experience, thanks to the inclusion of the EZ M.2 Shield Frozr II and the pre-installed I/O shield. The board feels substantial, and the thermal management—highlighted by the enlarged VRM heatsinks with 7 W/mK thermal pads—effectively keeps the power delivery cool under sustained loads. The inclusion of physical Clear CMOS and Flash BIOS buttons provides a safety net for those experimenting with memory timings or CPU settings.
Compared to the previous B650 generation, the B850 chipset introduces significant upgrades in bandwidth, most notably the dual PCIe 5.0 M.2 slots which were previously rare in the M-ATX segment. While full-ATX boards offer more PCIe expansion slots, the MORTAR series maintains its reputation for providing the most essential high-end features in a footprint that fits a wider variety of chassis.
