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

As it currently stands, MSI has unveiled a single mini-ITX model to cater to small form factor users and enthusiasts, the MSI MPG B550I Gaming Edge Wifi. Following a similar design to the ATX sized B550 Gaming Edge Wifi, the smaller mini-ITX version is packed with features including an 8-layer PCB, a full-length PCIe 4.0 x16 slot, two M.2 slots, with a Realtek 2.5 GbE Ethernet controller and Wi-Fi 6 interface pairing.
The MSI MPG B550I Gaming Edge Wifi is using an all-black theme throughout with subtle grey accents on the rear panel cover and heatsinks. The bulk of the feature set hangs around B550's PCIe 4.0 support including one full-length PCIe 4.0 x16 slot, one PCIe 4.0 x4 M.2 slot, and a second PCIe 3.0 x4 M.2 slot. Although B550 models have generally ditched the actively cooled chipset heatsinks, the B550I Gaming Edge Wifi includes a cooling fan in what looks to be an amalgamation between the chipset heatsink and the PCIe 4.0 x4 M.2 slot. For conventional SATA drives, MSI includes four straight-angled SATA ports with support for RAID 0, 1, and 10 arrays. While mini-ITX models have been favored for enthusiast memory overclockers due to shorter memory traces to the CPU, the B550I Gaming Edge Wifi supports up to DDR4-4600 officially which is much lower than other MSI MPG B550 models. Users can install up to 64 GB across two available memory slots.
The rear panel includes a varied selection of IO including a single USB 3.2 G2 Type-C, two USB 3.2 G1 Type-A, and two USB 2.0 ports. MSI includes a single HDMI 2.1 video output for users looking to opt for a Ryzen based APU, while a PS/2 keyboard and mouse combination port allows the use of legacy peripherals. For networking, there is a Realtek RTL8125B 2.5 GbE Ethernet controller, with an Intel AX200 Wi-Fi 6 interface which also allows the use of BT 5.0 devices. Rounding off the rear panel is a small BIOS Flashback button, and five 3.5 mm audio jacks and a single S/PDIF optical output which is powered by a Realtek ALC1200 HD audio codec.
The MSI MPG B550I Gaming Edge Wifi is the only mini-ITX model at launch from the company, and it is seen as a direct replacement to the B450I Gaming Plus AC. While it offers a better controller set and includes official support for PCIe 4.0 via the full-length PCIe 4.0 x16 slot and PCIe 4.0 x4 M.2 slot, it comes at the much more premium price of $200. With two USB 3.2 G2 slots including a Type-A and Type-C pairing, and a Realtek RTL8125B 2.5 G Ethernet controller, with Wi-Fi 6 and two M.2 slots, it looks a competitive model in the mid-range mini-ITX market space.

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
I ordered this then I quickly cancelled and ordered B550I AORUS PRO AXQuestor - Sunday, July 12, 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".
