The motherboards pictured today include the MAG B660 Tomahawk, MAG B660M Mortar, MAG B660M Bazooka, and Pro B660M-A DDR4. All four motherboards pictured are DDR4 variants but they will also be available in DDR4 flavors too. As reported by, chi11eddog, all four motherboards come with a 12 phase power delivery and feature dual 8-pin connectors to boot. This means that the motherboards will be powerful enough to support all 12th Gen Alder Lake CPUs up to the i9-12900K.


Other features include a 2.5G LAN, an EZ M.2 clip for easier M.2 SSD installation, a 6-layer (2oz) copper PCB design, and a good array of IO capabilities. MSI's B660 motherboards look very nice and even the entry-level PRO model seems to carry decent heatsinks for the VRMs and even has the M.2 heatsink for the primary slot. This motherboard would cost $189 US but there would be more entry-level Pro models in the sub-$150 US category.


For the other motherboards, we know from our previous pricing leak that the MAG Tomahawk WiFi DDR4 would cost around $239 US, the MAG Mortar WiFi DDR4 would cost around $219 US and the MAG Bazooka DDR4 would cost around $179 US. The Mortar WiFi can be seen as a premium Micro-ATX option which features dual full-length PCIe slots and dual M.2 slots with heatsinks.  The B660M Bazooka being a more cost-effective option comes with a single M.2 heatsink and a slightly smaller VRM heatsink but other features are mostly the same. The Tomahawk being the full ATX option has all the features you'd expect from a $250 US board.

Expect the motherboards to launch on the 4th of January after Intel unveils its non-K Alder Lake CPU lineup.
