Socket LGA 1700 Micro ATX motherboard

The MSI MAG B760M MORTAR II is a Micro ATX board built on the Intel B760 chipset for LGA 1700 processors. It supports Intel Core 12th, 13th and 14th generation CPUs as well as Pentium Gold and Celeron models. The board provides a compact foundation for a DDR5 system with up to 256GB of memory.

Verify CPU cooler clearance and power phases

Before ordering, confirm that your case accepts a Micro ATX form factor and that the CPU cooler mounting holes match the LGA 1700 pattern. Check that your power supply delivers the required 12V and ATX connectors for the board's voltage regulator layout. Ensure the rear I/O cutout aligns with the supplied back panel.

Bundled SATA cable and I/O shield only

The package includes one SATA cable and the chassis I/O back panel. No additional cables, Wi-Fi antennas or driver media are supplied. The single SATA cable connects one drive to the four SATA III ports. The back panel simply covers the rear port cutout in the case.

Questions about this item

What comes in the box and what do I need to buy separately?

The package includes the motherboard, one SATA cable and the chassis I/O back panel; CPU, DDR5 memory, storage drives and a cooler must be purchased separately.

Which memory speed should I choose from the supported list?

The board supports DDR5 from 4800 MHz JEDEC up to 7800 MHz overclocked; pick a kit that matches your CPU's memory controller and your budget.

What does the 256 GB maximum memory figure mean in practice?

You can install up to 256 GB of DDR5 across the four slots, allowing very large workloads provided you use compatible high-capacity modules.
