ASUS have regenerated their Prime X299 Deluxe motherboard to be able to support new Intel chips such as the i9-9980XE by completely redesigning the PWMs and adding a few new features.  This is the third board which [H]ard|OCP reviewed that uses the new "Twin phase" design as opposed to the previous phase doubling used on the vast majority of boards.  Their results so far suggest the new design is at least as stable as the old standard, as you can see yourself in their full review.

"The ASUS Prime X299 Deluxe II is an ultra-feature rich solution for today’s discerning computing enthusiast. It does not wear ROG branding, and is clad in white shrouding, letting you know that this is a PRIME motherboard. Is it a bargain priced motherboard? Nope. This one comes in at $500. Let's see if it is worth it."
