The AMD B550 Motherboard Overview: ASUS, GIGABYTE, MSI, ASRock, and Others
by Dr. Ian Cutress & Gavin Bonshor on June 16, 2020 11:00 AM ESTASRock B550 Phantom Gaming-ITX/ax
The budget chipsets are often a good place to find the smaller mini-ITX based motherboards, because in those small form factors, users are unlikely to be pushing the frequency limits of their processors, and something using less power and is more compact often benefits the design. This this case the B550 PG-ITX/ac seems to be a more mid-range platform, with a rear IO cover as well as a combination M.2 and chipset heatsink at this size.
There are three 4-pin fan headers on this motherboard total, often a minimum for these sorts of systems, and they are equally placed around the board. There are RGB LEDs on the edge of the board at the bottom, as well as a pair of RGB LED headers at the top for anyone who wants to add some flash. As with most designs of this size, there are only two DDR4 memory slots.
On the right hand side we get a 24-pin ATX power connector, four SATA ports in a standard configuration (this is good, normally they are sticking out of the motherboard on mITX), a USB 3.0 header, a USB 2.0 header, a front panel header, and a Type-C header.
The PCIe 4.0 x16 slot is reinforced, and the PCIe 4.0 x4 slot is just above this, sharing the heatsink with the chipset. There is another PCIe 3.0 x2 M.2 slot on the rear of the motherboard. Just to the left of the chipset is the ALC1220 audio, although there isn’t much more room to offer an improved audio scenario.
On the rear panel we have the Intel I225-V 2.5 gigabit Ethernet port, a Type-A USB 3.2 Gen 2 port, a Type-C USB 3.2 Gen 2 port, DisplayPort, HDMI, four USB 3.2 Gen 1 ports, the audio jacks, and antenna for the Intel AX201 Wi-Fi 6 module.
Truth be told, with these features, users will be hard pressed to tell the difference between most X570 mini-ITX motherboards and this motherboard.

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
Why so expensive...cybersirf - Friday, June 19, 2020 - link
more expensive, less features. what happened to x2 slots?miss5tability - Saturday, June 20, 2020 - link
whata abiut VRM the biggest issue on b450 MOBOs, i dont see any single word about that ? wtfMem - Saturday, June 20, 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.
