LGA 1151 DDR4 ATX Motherboard

The MSI H270-A PRO is an Intel H270 motherboard for LGA 1151 processors. It supports 6th and 7th generation Intel Core i3, i5 and i7 CPUs plus Pentium and Celeron models. Dual-channel DDR4 memory runs at 2400 or 2133MHz up to a 64GB maximum. The board uses the standard ATX form factor.

Builders keeping 6th or 7th gen Intel CPUs

This board suits owners of LGA 1151 processors who need a replacement H270 platform with 64GB memory headroom and multiple expansion slots. It provides two PCIe 3.0 x16 slots, four PCIe 3.0 x1 slots and six SATA III ports. Builders starting a new system or using 8th generation or newer Intel CPUs should choose a different socket and chipset.

64GB DDR4 Maximum Memory

The 64GB DDR4 limit is the key figure for capacity planning. Four DIMM slots accept dual-channel kits at 2400 or 2133MHz. If the workload requires more than 64GB of system memory, this motherboard cannot meet that requirement and a different platform must be selected.

Questions about this item

What size case and mounting pattern does the MSI H270-A PRO ATX board need?

The board follows the standard ATX form factor, so it fits any case with ATX standoffs and the matching I/O shield cut-out.

How is the board installed and which step is often missed?

Mount the board on ATX standoffs, attach the supplied I/O shield, connect the 24-pin and 4-pin power cables, then seat the LGA 1151 CPU, DDR4 modules and SATA cables; the step most often missed is fitting the I/O shield before the board.

Which on-board component will need replacement later?

The included CMOS battery keeps the real-time clock running and will need replacing when the system starts losing date and time after power-off.
