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 B550M Steel Legend
The smaller mATX version of the Steel Legend is, for the most part, similar to the larger version but with the same features in a smaller form factor. We still get the design that comes across as a stainless steel implementation, with RGB LEDs on the rear panel cover and chipset heatsink, but this time the chipset heatsink covers the main M.2 slot rather than the secondary one (and the secondary one doesn’t have a heatsink at all).
The CPU power is an 8-pin and a 4-pin, and the socket area has access to three 4-pin fan headers within easy reach. The DRAM slots are single sided latch designs, and on the right hand side of the board we get an RGB LED header, the 24-pin ATX connector, the USB 3.0 header, two vertical SATA ports, and four regular SATA ports. All the SATA ports in this configuration come from the chipset, with no additional controllers.
On the bottom of the board is another RGB LED header, three more fan headers, two USB 2.0 headers, and another USB 3.0 header. Above this is a PCIe 3.0 x2 slot without a heatsink.
The PCIe slots are configured for an x16 PCIe 4.0 from the CPU, and the other full-length slot is a PCIe 3.0 x4 from the chipset. On the right side of the board is the upgraded audio, which has signal separation, filter caps, and runs a Realtek ALC1200 codec without an additional amp.
On the rear panel of the motherboard, we get a Clear CMOS button, HDMI video output, Display Port, two USB 2.0 ports, a combination PS/2 port, a Type-A USB 3.2 Gen 2 port, a Type-C USB 3.2 Gen 2 port, four USB 3.2 Gen 1 ports, a Realtek RTL8125BG 2.5 gigabit Ethernet port, and 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
Why so expensive...cybersirf - Friday, June 19, 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.
