The MSI X399 Gaming Pro Carbon AC is a new motherboard based on the new AMD HEDT chipset. It features the TR4 socket which fully supports the AMD Ryzen Threadripper processors. It comes with quad channel DDR4 memory support and has eight DDR4 DIMM slots scattered across the socket. The CPU is powered by dual 8 pin connectors which provides a massive influx of power to the board. HEDT users and over clockers will definitely enjoy the 13 Phase (10+3) DrMOS power delivery system which ensures a lot of power being delivered to the socket for overclocking needs.
