Intel B760 micro-ATX for LGA 1700

The MSI MAG B760M MORTAR MAX WIFI DDR4 is a micro-ATX motherboard built around the Intel B760 chipset and LGA 1700 socket. It supports Intel Core 12th, 13th and 14th generation processors as well as Pentium Gold and Celeron CPUs. The board provides dual-channel DDR4 memory up to 128 GB and includes integrated 2.5 Gbps LAN, Wi-Fi antenna support and 7.1-channel audio.

Builders who need DDR4 memory

This board suits builders reusing DDR4 modules or choosing DDR4 for cost reasons while still wanting PCIe 5.0 for a graphics card and multiple M.2 slots. It also fits users who need front-panel USB 20 Gbps Type-C and rear USB 10 Gbps ports. Users requiring more than two full-length PCIe x16 slots or a full-size ATX layout should look elsewhere.

PCIe 5.0 x16 slot from the CPU

The primary PCIe x16 slot runs at PCIe 5.0 directly from the processor, delivering maximum bandwidth for current and future graphics cards. A second x16-sized slot operates at PCIe 3.0 x1 from the chipset, and a third provides PCIe 4.0 x4 for additional add-in cards. This lane allocation determines how many high-speed devices can run simultaneously.

Questions about this item

What PCIe generation does the primary x16 slot use and what bandwidth does it deliver?

The primary PCIe x16 slot runs at PCIe 5.0 and delivers up to x16 bandwidth directly from the CPU.

What are the board dimensions and mounting standard for this Micro ATX motherboard?

The board follows the Micro ATX form factor and uses the standard Micro ATX mounting hole pattern for compatible chassis.

How is the Wi-Fi antenna attached and what is the common installation mistake?

Screw the supplied external antenna onto the rear I/O gold connectors; the step often missed is tightening both antenna leads before powering on.
