Mosfets could be also cooled from the back of MB even if there are no actual chips there. It can help a lot.

Any plans to update the OP with AM4 boards?

Never heard of that one. Who the hell makes that one ? Seems like it's a "sticker engineering" from somebody else than Chameleon.

Very nice looking BUT have no idea as to it's VRM particulars, so if any tech expert can shine a light on this one here that would be appreciated.

Highly unusual to see some no-names vying for the AMD Ryzen moolah, fake or real, who knows.......

It's a 4+2 phase VRM, I'm not pretty sure by which controller it is driven. It's a WQFN-52L 6x6 package and it doesn't seem to be an ISL95712, also there is no fitting Richtek controller even if the markings look like it's a RT controller. I'd guess it's a uPI uP9505. If that's the case it would be what's called a "hybrid" controller, so it's still using a analogue backend.

The highside FET for the SoC VCC is a MagnaChip MDD1502 and the lowside is a MDD1501, there is just one of them per phase.
These FETs are pretty decent I'd say, max on-resistance for the lowside @10V VGS is 5.6mOhm, rise- + fall-time for the highside is 20.1ms.
The lowside for the CPU VCC could be doubled which isn't a bad idea at all since switching losses for the lowside aren't high at all too.

Thanks br0da, it was just surprising that anyone else other than MSI, Asrock, Asus, Biostar and Gigabyte would build and sell another B350 motherboard.

Wonder if there are MORE models out there that the whole community knows nothing about?

Oh I think there are a couple of boards out there that most of us don't know. E.g. SUPoX, Colorful or Soyo are only selling there boards in China. Pictures of some of them can be found here: https://www.hardwareluxx.de/community/f12/ubersicht-amd-am4-mainboards-news-specs-reviews-bilder-alle-plattformen-1135676.html

Strange looking board: three PCIex16 slots and TWO M.2 slots -- on a B350 chipset??

I may be don't get it, but I think it's trying to appear to be something it doesn't have the cajones to back up.
