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 TUF Gaming B550M-Plus + Wi-Fi
For the TUF small form factor board, technically ASUS is going to offer two different models here, one with AX200 Wi-Fi 6 and one without. The price for the B550M-Plus with the Wi-Fi is an extra $20, which is in-line with what we’ve seen from other Wi-Fi 6 variants. At $160 for the base model, it still feels as if this should be on the high-end for a budget chipset, but this is actually around the middle.
The ASUS TUF Gaming B550M-Plus (and Wi-Fi variant) follow similar design cues to the ATX B550-Plus model. It’s a similar styling with grey diagonal lines from top left to bottom right, with some TUF yellow thrown in, and the chipset heatsink covers both sides of the power delivery, but without a heatpipe.
The CPU is powered by a single 8-pin to the top left, and the socket area has access to three 4-pin fan headers within easy reach. The memory slots are all single-sided latch designs, and down the right of the board we get only a 24-pin ATX power connector and a USB 3.0 header. For this board, ASUS has moved all the SATA ports to the bottom of the board! At least in this configuration, it makes removing any of them very easy to do.
The PCIe configuration for the board shows that the top slot is focused on the PCIe 4.0 x4 M.2 slot, without a heatsink so users can have their own. Below this is the main PCIe 4.0 x16 slot, with additional reinforcement. We have then a PCIe 3.0 x4 M.2 slot from the chipset, and a full-length PCIe 3.0 x4 slot from the chipset. The chipset heatsink, like on the B550-Plus is relatively small but should be sufficient.
Along the bottom of the motherboard we get a COM header, RGB LED headers, another 4-pin fan header, two USB 2.0 headers, the front panel header, and the four SATA ports. The audio system uses the same S1200A audio codec as the ROG Strix family, but without the additional amps.
On the rear panel we get a combination PS/2 connector, two USB 2.0 ports, four USB 3.2 Gen 1 ports, a BIOS Flashback button, Wi-Fi ports (for the Wi-Fi model), a DisplayPort, a HDMI port, 2.5 gigabit Ethernet (Realtek RTL8125B), a USB 3.2 Gen 2 Type-A port, a USB 3.2 Gen 2 Type-C port, and the audio jacks.

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
I need help..the mob manual says the m.2 slot for the chipset suport sata n pcie 3.0x2..but this review says it suport pci3.0x4..i bought a samsung 970 evo with a pcie 3.0x4..can it be used in the slotIqbalusamah - Sunday, October 25, 2020 - link
Help me..i cant understand which one is true..the 2nd m.2 slot for chipset runs at pci3.0x4 or pcie 3.0x2(mob manual).and can a pcie3.0x4 be used in the slotZwirley - Sunday, July 18, 2021 - 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".
