LGA 1700 Micro ATX Motherboard

The MSI MAG B760M MORTAR WIFI II fits LGA 1700 processors from the 12th, 13th and 14th generations, plus Pentium Gold, Celeron and the 300 series. It uses the Intel B760 chipset on a Micro ATX PCB with a 12+1+1 Duet Rail power system and dual 8-pin CPU connectors. Four DDR5 slots support up to 192GB in dual-channel mode.

DDR5 Overclocking Focus

Builders who want high DDR5 frequencies will appreciate the board's validated speeds up to 7800+ MHz with one single-rank module. Users planning to fill all four slots should expect lower ceilings, dropping to 5600+ MHz with two dual-rank kits. Systems that only need JEDEC speeds or ECC memory should consider other platforms.

Three M.2 Slots and 2.5Gbps LAN

The primary M.2 slot runs at PCIe 4.0 x4 from the CPU and accepts 2280, 2260 and 2242 drives. Two further chipset-linked slots add PCIe 4.0 x4 for 2280 and 2260 devices. A 2.5Gbps LAN port, Wi-Fi 6E with 160MHz channels and Bluetooth 5.3 handle networking. Four SATA 6Gb/s ports support RAID 0, 1, 5 and 10.

Questions about this item

Will my existing LGA 1700 CPU cooler fit the socket on this MAG B760M MORTAR WIFI II?

Yes, the board uses the standard LGA 1700 socket so any cooler rated for that mounting pattern will fit.

Can I keep my SATA SSDs and hard drives when moving to this motherboard?

The board provides four SATA 6Gb/s ports and supports RAID 0, 1, 5 and 10 for those drives.

How do I confirm the Wi-Fi 6E and Bluetooth 5.3 are active after building?

Open Windows Device Manager and check that an Intel Wi-Fi 6E adapter and a Bluetooth 5.3 radio appear without error icons.
