Introduction
Our review is evaluating a brand new entry from MSI into their “MAX” AM5 motherboard lineup. The MSI MAG B850M Mortar MAX WiFi is a refreshed version of the MSI MAG B850M MORTAR WiFi that we reviewed in July 2025.
The MAG (MSI Arsenal Gaming) tier is the entry-level gaming platform offered by MSI. This generally includes the GAMING PLUS WiFi, the TOMAHAWK WiFi, and the MORTAR. On this case, the Mortar is the lone MATX board. Despite their entry-level position, all of those boards are nicely outfitted, offering every feature the chipset and CPU have available.
The “MAX” moniker indicates this board is the most recent release and supports all of the most modern features MSI has to supply. The MSI MAG B850M MORTAR MAX WiFi has every item from the OG, plus the brand new “MSI OC Engine”, a 64MB BIOS chip, 4 M.2 slots, some additional BIOS selections, and a brand new prolonged heatsink design. All of this functionality has been compressed onto an MATX board. A refresher of the AMD chipset lineup is positioned here.
On the time of writing, the MAG B850M MORTAR MAX WiFi has not been released into retail availability. On May 20, 2026, we received an email from MSI stating that it had decided to not release the MAG B850M Mortar MAX WiFi for retail sale in North America, but it can be available in other regions. There have been no other details. We’d expect the worth to be within the neighborhood of the unique, $239. This motherboard carries a three-year warranty.
Packaging and Contents
The motherboard was shipped directly from MSI. This can be a full retail package. We found the same old packing format. The board was placed inside an anti-static bag and guarded by cardboard inserts. The wifi antenna was packed on top, and the accessories underneath. The accessories included: booklets, a sheet of stickers, one SATA cable, an EZ-Con cable, two EZ-Clip M.2 screws, and the EZ Clip tool/screwdriver. It’s interesting that if we read the serial number appropriately, this was the thirteenth board that got here off the road in January 2026.
