The AMD B550 Motherboard Overview: ASUS, GIGABYTE, MSI, ASRock, and Others
by Dr. Ian Cutress & Gavin Bonshor on June 16, 2020 11:00 AM ESTIn regards to product stack size, MSI has quite a varied range of B550 models set for launch, with many of its series making a reappearance. This includes the Gaming Carbon with a premium controller set for a budget-focused chipset, and the Unify series known for its sleek all-black aesthetic makes its B series debut. Quite a few of MSI's models include 2.5 GbE Ethernet controllers, more so than it did with its X570 models, and makes it for a competitive selection for users to choose from.
MSI MPG B550 Gaming Carbon Wifi
Focusing on its premium B550 model, the MSI MPG B550 Gaming Carbon Wifi, it's very similar in design to the X570 Gaming Pro Carbon. Underneath the carbon inspired heatsinks is an advertised 12+2 power delivery, with dual 12 V ATX CPU power inputs including an 8-pin and 4-pin pairing. The most notable features include support for DDR4-5100 memory, dual M.2 slots, a Realtek ALC1200 HD audio codec and a Realtek 2.5 GbE Ethernet controller.
Looking at PCIe support, the B550 Gaming Carbon Wifi includes two full-length slots including a PCIe 4.0 x16 and PCIe 3.0 x4 slot, with three additional PCIe 3.0 x1 slots. MSI includes four memory slots with support for up to DDR4-5100, with a combined total of up to 128 GB. For storage, there are two M.2 slots with the top slot supporting up to PCIe 4.0 x4 drives, while the second slot which is driven by the chipset and as a consequence, is limited to PCIe 3.0 x4. This is in additional six SATA ports with support for RAID 0, 1, and 10 arrays. MSI has included support for up to DDR4-5100 memory, with a combined total of up to 128 GB across four memory slots.
On the rear panel is a whole host of connectivity real estate which includes a single USB 3.2 G2 Type-C, one USB 3.2 G2 Type-A, two USB 3.2 G1 Type-A, and four USB 2.0 ports. A pair of video outputs including a DisplayPort and HDMI output, although MSI doesn't go into detail on the specifications. In regards to networking, the board is equipped with a Realtek RTL8125B 2.5 GbE Ethernet controller and an Intel AX200 Wi-Fi 6 interface which also includes support for BT 5.0 devices. Also on the rear panel is a handily located BIOS Flashback button, with the board five 3.5 mm audio jacks and S/PDIF optical output which are controlled by a Realtek ALC1200 HD audio codec.
The MSI MPG B550 Gaming Carbon Wifi directly replaces the previous B450 Gaming Carbon Max Wifi and has an MSRP of $220. This makes it the most expensive of MSI's B550 models and it looks to come with a solid design, 2.5 GbE Ethernet and Wi-Fi wireless networking. MSI has stuck to a design it knows and implements it all on a solid looking board if RGB enabled carbon inspired styling is the desired theme.

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:

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".
