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 ROG Strix B550-I Gaming
The sole entrant into the mini-ITX sphere from ASUS, at least at the time of writing, will be the B550-I Gaming. In true ASUS fashion, this motherboard does things a little differently than most. One of the biggest differences is the use of a separate audio daughter board for 3.5mm jacks. This daughter board combines onto one add-in with the M.2 slot, but the motherboard also has a Type-C audio port on the rear panel, and bundles in a Type-C to 3.5mm converter.
ASUS is again going for an angled mesh look, with there being a sizeable heatsink over the power delivery that morphs into the rear IO cover, as well as what seems like the M.2 heatsink. The 8-pin power connector is in the top left corner, sufficiently out of the way (a common problem on ITX boards).
The board has three 4-pin fan headers at the top, next to RGB headers, followed by two single-sided latch DDR4 slots. Along the right hand edge of the board are a 24-pin ATX connector, a USB 3.2 header, a USB 3.0 header, and four SATA ports all angled outwards. This makes the first two easy to remove when locking connectors are used, but the two inside will be hard to remove.
The single PCIe 4.0 x16 slot is reinforced at the bottom, and above this is the add-in audio board and M.2 heatsink combination. There is an additional PCIe 3.0 x4 M.2 slot on the rear of the motherboard.
On the back panel there is a DisplayPort, a HDMI port, a USB 2.0 port, a BIOS Flashback button, three USB 3.2 Gen 2 Type-A ports, a USB 3.2 Gen 2 Type-C port, a 2.5 gigabit Ethernet port (I225-V), Wi-Fi 6 (AX200), audio from the S1200A custom codec with SupremeFX trimmings, and a Type-C audio output.

The second M.2 slot for the Aorus Elite seems to support PCIE3.0x2 instead of x4 stated in the review unless I read wrong. Could anyone else confirm? This is the swaying factor for me to lean towards the Mortar. Specs from Gigabyte website below:Storage Interface
1 x M.2 connector (M2A_CPU), integrated in the CPU, supporting Socket 3, M key, type 2242/2260/2280/22110 SSDs:
3rd Generation AMD Ryzen™ processors support SATA and PCIe 4.0 x4/x2 SSDs
3rd Generation AMD Ryzen™ with Radeon™ Graphics processors support SATA and PCIe 3.0 x4/x2 SSDs
1 x M.2 connector (M2B_SB), integrated in the Chipset, supporting Socket 3, M key, type 2242/2260/2280 SSDs:
Supporting SATA and PCIe 3.0 x2 SSDs

Almost all of the boards include PS/2 connector. Why they put it in 2020? They stopped making PS/2 devices 15 years ago. Better would be to have an empty space there.Ethos Evoss - Sunday, July 5, 2020 - link

"One of the main complaints about the AMD X570 motherboard line was the wide variation in pricing."This can't be said of Intel based motherboards? Yes it can and accurately so. What is the point with this pointless statement?

Does the WiFi module connect to any WiFi Network, or is it only ASUS Networks if so would I need to buy a WiFi adapter?CamoGeko - Sunday, August 30, 2020 - link
Hey, so is there any cheaper alternative to the Aorus 550M Pro with similar or better feature set? I'm in the middle of building a Ryzen system with 3300X and motherboard is the last thing I need to decide on. Other mATX at the same price or cheaper just don't look as good as the B550M Aorus Pro.Iqbalusamah - Sunday, October 25, 2020 - link

Question, is this board capable of overclocking and does it have a good power phase design? I was wondering because I want to build an all-white system but then came across another concern of this motherboard and that is if this supports BIOS Flashback feature so that I don't have to go out of my way to purchase an older gen CPU for it to support my 5900xcharlesa365 - Tuesday, August 3, 2021 - link
My personal computer running Debian has had four GIGABYTE B550 Vision D motherboards. The first and fourth had NIC initialisation on power up problems. The second one's NICs died after ~6 months. The third did not show voltage/temperature values properly. GIGABYTE warranty agents wrote "We do not give support to Debian OS".
