Verdict

The MSI B350M Mortar Arctic is a Micro-ATX motherboard featuring a striking white PCB with white LED lighting, built on the AMD B350 chipset for AM4 socket processors. It supports up to 64GB of dual-channel DDR4 memory with overclocked speeds reaching 3200MHz+ and includes a 4+2 phase power delivery system suitable for moderate overclocking. Connectivity is highlighted by a single Turbo M.2 slot (PCIe 3.0 x4), four SATA 6Gb/s ports, and a rear I/O offering USB 3.1 Gen1 Type-C, HDMI, DisplayPort, and DVI-D for integrated graphics. Main pros include its unique 'Arctic' aesthetic, solid stability with high-speed RAM via A-XMP, and a reinforced Steel Armor PCIe slot for heavy GPUs. However, it lacks USB 3.1 Gen2 (10Gbps) support, uses an older Realtek ALC892 audio codec, and features uncooled SOC VRM phases, which can limit extreme overclocking stability.
