Socket LGA 1151 MicroATX board

The MSI B360M MORTAR is a new Intel motherboard built for the LGA 1151 socket in a MicroATX form factor. It supports DDR4 memory up to 64 GB and provides a single PCI Express 3.0 x16 slot for a graphics card. The rear I/O includes a DisplayPort and a USB 3.1 Gen 2 Type-A port.

Builders using 8th or 9th Gen Intel Core CPUs

This board suits builders assembling a compact system around a compatible LGA 1151 processor who need dual M.2 slots and a legacy PCI slot. It is not for buyers who require more than one full-size PCIe x16 slot or who need integrated Wi-Fi or Bluetooth connectivity.

Maximum memory capacity of 64 GB

The 64 GB DDR4 limit determines whether this motherboard can meet the memory demands of the intended workload. Buyers planning to exceed that capacity will need to select a different platform.

Questions about this item

How much DDR4 memory can the B360M MORTAR handle before it hits its ceiling?

The board supports up to 64GB of DDR4 memory across its slots.

What happens to thermals and fan noise when the VRM and chipset run at full tilt all day?

The B360 chipset and VRM area are passively cooled, so sustained loads rely on case airflow rather than dedicated fans.

Which storage cables and I/O brackets are missing from the box that I need to source myself?

Only the motherboard and I/O shield are included; SATA cables, M.2 screws and any Wi-Fi antennas must be purchased separately.
