The AMD B550 Motherboard Overview: ASUS, GIGABYTE, MSI, ASRock, and Others

It looks like ASRock will have a second mini-ITX motherboard, this time on the cheaper end of the scale. The B550M-ITX/ac, at first glance however, seems to have some rough layout choices. First of all, the CPU 8-pin connector, is on the rear panel. Whoever thought that was a good idea needs removing from the design team.
The CPU power delivery seems to be an 8-phase design, with a small heatsink to assist. The socket area has two 4-pin fan headers above it to assist, and there is a third on the bottom right of the board, although this is a bit far away for any air coolers. The two DRAM slots in between are single sided latch designs.
On the right hand side of the board is the 24-pin ATX power connector, and four SATA ports in a configuration which makes taking two of the locking cables out impossible if memory is installed – again, an odd design choice. Below this are a USB 3.0 header, a USB 2.0 header, the front panel header, and that third 4-pin fan header.
The chipset and PCIe 4.0 x4 M.2 slot have one combined heatsink, just above the PCIe 4.0 x16 slot. The PCIe slot doesn’t have additional support embedded in it. To the left is the audio codec, in this case it’s the low-end ALC887 design.
The rear panel has a DisplayPort, a HDMI port, two USB 3.2 Gen 1 ports, two USB 2.0 ports, a combination PS/2 port, gigabit Ethernet from a Realtek RTL8111H controller, a Type-A USB 3.2 Gen 2 port, a Type-C USB 3.2 Gen 2 port, audio jacks, and Wi-Fi antenna for the built in Wi-Fi 5 module (likely Intel’s 1x1 AC3168 solution).

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.
