This Computex, we are on the lookout for motherboards based on Intel Z390 and upcoming AMD chipsets such as the B450, or even the Z490; but a new X399 motherboard for the Ryzen Threadripper was the last thing we expected. Imagine our shock at the sight of the MSI MEG X399 Creation. This board has the most polarizing, in-your-face design from MSI since the mid-2000s (roller-coaster heatsinks, anyone?). The board appears to be clearly wider than ATX spec, and approaching E-ATX territory.A humongous L-shaped heatsink dominates the bottom-right corner, cooling not just the AMD X399 chipset, but also three M.2 slots. The top-left, and far-left corners feature some of the largest CPU VRM heatsinks we've seen in a long while. The VRM heatsink extends to the left side, while the rear-I/O shroud blends into it, running the entire length of the left side. The board gives you a maximum of 7 M.2 slots. A 19-phase VRM drawing power from two 8-pin EPS connectors fuels your Threadripper. Four PCIe 3.0 x16 slots, eight DDR4 DIMM slots, and the whole shebang of OC features make for the rest of it.
