MSI showed off two of its latest socket AM4 motherboards based on AMD's upcoming B450 chipset, the B450 Tomahawk and B450-A Pro. The Tomahawk is slotted in MSI's minimalist yet gamer-grade Arsenal Gaming series, and has a clean look, with a feature-set that doesn't exceed that of the chipset by much. Slick new VRM and chipset heatsink designs which debuted with Intel 300-series Tomahawk boards, make their appearance here. There's just one M.2-22110 slot. The B450-A Pro is part of MSI's mainline motherboard lineup, and targeted at system-integrators, with a similar feature-set to the Tomahawk, though slightly built to a cost.
