ECS showed off its B350AM4-M, which appears to be the company's only socket AM4 motherboard, for now. This micro-ATX board is based on AMD's mid-tier B350 chipset. The board draws power from 24-pin ATX and 4-pin CPU power connectors, and conditions it for the CPU with a 6-phase VRM. Expansion slots include one PCI-Express 3.0 x16, a second x16 slot that's electrical x4, and one each of x1 and legacy PCI slots. Storage connectivity includes two M.2 slots, and four SATA 6 Gb/s ports. 6-channel HD audio, and gigabit Ethernet make for the rest of it.
