MSI today introduced the B350 Gaming Plus, a gaming-grade socket AM4 motherboard based on the mid-range AMD B350 chipset. Built in the ATX form-factor, the board is based on the same PCB as the B350 Tomahawk, and draws power from a combination of 24-pin ATX and 8-pin EPS power connectors, and conditions it for the AM4 SoC with a 6-phase VRM. The AM4 socket is wired to four DDR4 DIMM slots, supporting up to 64 GB of dual-channel DDR4 memory; and one PCI-Express 3.0 x16 slot, with a metal reinforcement brace. The second x16 slot is electrical x4, and wired to the B350 chipset. Two each of PCIe x1 and legacy PCI make for the rest of the expansion area.

Storage connectivity on the MSI B350 Gaming Plus includes four SATA 6 Gb/s ports, and one 32 Gb/s M.2 slot with NVMe booting support. USB connectivity includes eight USB 3.0 ports (six on the rear panel including a type-C port, and two via headers). Display outputs include one each of DVI, D-Sub, and HDMI. The onboard audio solution combines a Realtek ALC892 8-channel HD audio CODEC with ground layer isolation, and audio-grade capacitors. Gigabit Ethernet is handled by a Realtek RTL8111H controller. We expect the board to be priced around the $120 mark.
