The AMD B550 Motherboard Overview: ASUS, GIGABYTE, MSI, ASRock, and Others
by Dr. Ian Cutress & Gavin Bonshor on June 16, 2020 11:00 AM ESTASUS Prime B550M-K
ASUS’s cheapest B550 board is the B550M-K, which is almost identical to the B550M-A, with just fewer parts. The biggest visual difference is that the B550M-K does not come with a power delivery heatsink, with a simple 4+2 power delivery design.
This does make the board look a lot cleaner with its straight lines, however this isn’t going to be a board for pushing the boundaries. It has only two fan headers around the socket, has a smaller chipset heatsink, and is missing some of the headers on the bottom of the board, such as the one for Thunderbolt or RGB. The latter might be a good thing.
Users will still have a USB 3.0 header, two USB 2.0 headers, four SATA ports, a full PCIe 4.0 x16 slot, a PCIe 4.0 x4 M.2 slot for fast storage, and a PCIe 3.0 x4 M.2 slot from the chipset. Audio is the same ALC887 codec with some PCB separation.
On the rear panel the user will get a combination PS/2 port, four USB 3.2 Gen 1 ports, an analog D-Sub video output, a DVI-D video output, a HDMI video output, two USB 3.2 Gen 2 Type-A ports, a gigabit Ethernet port (Realtek RTL8111H), and the audio jacks.

Same here. Both DVI and DP can be converted to VGA using an inexpensive passive dongle. I'd much rather see either of those ports over VGA.Gigaplex - Saturday, August 1, 2020 - link
DVI-I can be converted easily. DVI-D (which most of the modern boards have) need a more complex adapter.iranterres - Thursday, June 18, 2020 - link

I believe you will find Asus use S1220A so not S1200A , it's custom version of ALC1220, when you go by Asus website for their B550 boards.awonglk - Saturday, June 20, 2020 - link
There seems to be no mentions of Thunderbolt 3 header that apparently comes with this motherboard according to Asia’s own website:https://edgeup.asus.com/2020/b550-motherboard-guid...
Does anyone know how or what this connects to on a mITX motherboard?

Does "USB 3.2 G2 Type-C" imply Thunderbolt 3 support?dennphill - Friday, June 26, 2020 - link
And here it is a couple of weeks after the 'release' and there are no boards (well, no mATX versions) to buy...unless you want to deal with the scalpers on NewEgg asking $25 to 35 over the regular price - oh, and BTW, they will ship/deliver in mid-July - AND I see no reviews or comparisons other than manufacturers' sites advertising for the B550 boards. The few articles I see are all based on the pre-release data and not from actual delivered, installed and tested MBs. Poor AMD hardware release, as far as I am concerned.dennphill - Friday, June 26, 2020 - link
Oh, and the listing is incomplete with a couple of manufacturer-advertised versions od mATX boards not listed in this article.
