This may be as close as we get to an admission from the motherboard makers that the original X299 boards were not adequate for the job. Certainly, the 18 core Skylake X pulls an immense amount of current. You expect that with a refresh, you will see new boards (ex: Asus is known to release a "Black" edition of its Rampage series with a die shrink), but not this soon after.
I expect that other motherboard manufacturers to follow suit.
The Taichi are usually one of Asrock's value oriented boards, so it will be interesting to see how this XE edition is priced. They probably rushed X299 in the face of AMD's Threadripper, which led to a sub-optimal solution. This is now the more optimal motherboard solution for X299.

It seems they added a second 8 pin power connector too. That's pretty crazy seeing how the OC Formula has 8+4 pin.
Note as well the more optimal heatsink on that X299 Taichi XE. Asrock claims there is a slightly beefed up VRM, which is certainly possible. That's needed considering these CPUs are drawing over >300W of power. There will be quite a bit of VRM heat due to the conversion from 12V to IVR voltage, even if they are using the 12 Intersil VRMs.
It kind of resembles the MSI X399 Gaming Pro Carbon VRM heatsink. Likewise, it has an 8 + 8 power connector, which is well advised.
Actually, AlphaC, this may very well push this Taichi XE into one of the best X299 boards. I wonder if there will be revised X299 Professional Gaming, OC Formula, and perhaps a flagship board (ex: an X299 Supercarrier) by Asrock?
The lesson here is to not jump into a platform too quickly. The people who bought X299 boards with sub-optimal VRM cooling solutions are stuck watercooling the VRMs. There is no fix for a board with only an 8 pin rather than an 8 + 8 pin connector though, save buying a new board.
On X99, for all non-Asus boards, within a couple of months, they all released boards with OC Socket and USB 3.1. Asus of course offered an update with USB 3.1 with their Rampage V series as well as their other high end boards. Plus there is the opportunity for the BIOS to mature on the new platform. Every new launch has issues with their BIOS.Edited by CrazyElf - 10/5/17 at 5:40pm
