Great. More damn vampires. LOL.
Yeah, it seems as though it's a pretty decent board, but I don't know if it's worth the premium over the B450-F which has the 6+2 VRM configuration. If you are planning to overclock or run high speed memory, or need extra slots, OR upgrade to Ryzen 3000 series CPU, then it may be worth it for you. If you plan to run at the stock configuration, even with a 2700x, then I don't see the benefit really. And that's assuming the 12 phase isn't just the 6 phase doubled, which I'm pretty sure it is, but again there are no actual reviews of that board.
If you need the higher power phase, then I'd probably skip B450 and look at either doing X470 or paying a major premium for X570 with PCIe 4.0.
