Here are some of the first pictures of MSI B350 Tomahawk, an upcoming socket AM4 motherboard that comes with support for AMD Ryzen CPUs. Positioned in the company's "Arsenal Gaming" series, this board is based on AMD's mid-tier B350 chipset. It covers the entire feature-set of the B350 chipset. The board draws power from a combination of 24-pin ATX and 8-pin EPS power connectors. It conditions it for the AM4 processor/APU with a 4+2 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.

The second PCIe 3.0 x16 slot is electrical x4, and wired to the B350 chipset. Two each of legacy PCI and PCIe 3.0 x1 make for the rest of the expansion slots. Storage connectivity includes one 32 Gb/s M.2 slot, and four SATA 6 Gb/s ports. From these, two come directly from the APU/CPU. The board also offers up to eight USB 3.0 ports, gaming grade 8-channel HD audio (with ground-layer isolation and audio-grade capacitors); gigabit Ethernet, and display outputs that include HDMI, DVI, and D-Sub (which will be disabled when using Ryzen).
