MSI MAG B660M Mortar WiFi DDR4 Motherboard Review 031Like its name suggest, the design of the MSI MAG B660M Mortar WiFi DDR4 is heavily military-inspired with the silver heatsinks spanning throughout the Micro-ATX motherboard having a reinforced steel design. The silver and black aesthetic makes for a refreshing look in a world that’s dominated by RGB lighting and dystopian designs.

MSI MAG B660M Mortar WiFi DDR4 Motherboard Review 034Despite being a budget, DDR4 variant of the MAG B660M Mortar line, MSI didn’t skimp on its quality by using a black 6-layer PCB with 2oz copper in the DDR4 model.

There are two 8pin EPS 12V connectors on the MAG B660M Mortar WiFi DDR4 to support the latest Intel 12th Generation Core series processors up to the flagship Intel Core i9 12900K.

MSI MAG B660M Mortar WiFi DDR4 Motherboard Review 098Underneath the chunky silver VRM heatsinks is a 14-phase VRM configuration with 12 phases dedicated to the CPU or Vcore. MSI uses a Renesas RAA229132 controller to distribute power to the 60A Renesas ISL99360 SPS MOSFETs.

MSI MAG B660M Mortar WiFi DDR4 Motherboard Review 043Memory support on the MAG B660M Mortar DDR4 variant is decent with a max supported memory frequency of DDR4-4800.

MSI MAG B660M Mortar WiFi DDR4 Motherboard Review 052The MAG B660M Mortar comes with a pre-installed IO shield which follows the silver theme of the MAG-Mortar motherboards. Connectivity is pretty robust with four USB 2.0 Type-A ports, three USB 3.2 Gen 2 Type-A ports, one USB 3.2 Gen 2×2 Type-C port, and a 2.5G Ethernet port. Seven USB type-A ports fit my standard in IO although I would’ve preferred most if not all ports were USB 3.0 to maximize bandwidth. The MSI MAG B660M supports the latest WIFI 6 standard via the Intel AX201 module.

Each heatsink on the MSI MAG B660M Mortar WIFI DDR4 can be removed independently unlike most motherboards that have a single-block heatsink solution that extends up to the chipset. The two removable heatsinks on the MAG B660M Mortar are the M.2 heatsinks located at the top and bottom of the PCI-E area.

The M.2 heatsinks or what MSI calls M.2 Shield FROZR have a decent size and will sufficiently cool M.2 SSDs that have no built-in heatsinks. That said if your M.2 SSD already has a built-in heatsink, then there’s no need to use the heatsinks covers from the MAG B660M Mortar.
