Verdict

The MSI B250M Mortar is a Micro-ATX motherboard designed for 6th and 7th generation Intel processors using the LGA 1151 socket and Intel B250 chipset. It features four DDR4 DIMM slots supporting up to 64GB of RAM at speeds up to 2400MHz, one Turbo M.2 slot for NVMe SSDs (Intel Optane ready), and six SATA III ports. For connectivity, it includes a USB 3.1 Gen1 Type-C port, DisplayPort, HDMI, DVI-D, and an Intel Gaming LAN controller. Key pros include its durable 'Military Class 5' build quality with PCIe Steel Armor, highly versatile fan headers with both DC and PWM control, and a comprehensive rear I/O for its price point. However, notable cons include its locked B250 chipset that prevents CPU and memory overclocking, a single BIOS chip with no backup, and some reported flimsiness in the plastic I/O cover.
