B150A Gaming Pro LGA 1151 ATX motherboard

The MSI B150A Gaming Pro is an ATX motherboard built on the Intel B150 chipset for LGA 1151 processors. It supports Core i7, i5, i3, Pentium and Celeron CPUs alongside dual-channel DDR4 2133 memory up to 64 GB. Onboard video uses Intel HD 5000/4000 graphics with an HDMI output.

Suits single-GPU builds needing legacy PCI slots

This board fits builders who want a single PCIe 3.0 x16 graphics card and up to three conventional PCI cards for older add-in hardware. It is not suited for multi-GPU arrays because the second x16 slot runs at x1 speed when the primary slot is populated.

Dual-channel DDR4 2133 with two 288-pin slots

Memory capacity tops out at 64 GB across two slots running in dual-channel mode at 2133 MT/s. Buyers needing four DIMM slots or higher memory speeds should select a different chipset.

Questions about this item

What is the maximum memory capacity the B150A Gaming Pro can address?

The board supports up to 64 GB of DDR4 2133 across its two 288-pin slots running in dual-channel mode.

How loud or hot does the board get when the system runs continuously?

The B150 chipset and Intel I219-V LAN are low-power components with no active cooling, so the motherboard itself adds minimal heat or noise during all-day operation.

Which processor and memory must I already have for this board to work?

You need an LGA 1151 Intel Core i7, i5, i3, Pentium or Celeron CPU plus DDR4 2133 modules; the board does not support other socket types or memory generations.
