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-E Gaming
Out of ASUS’ three main sub-brands for B550, the Strix is aimed at the higher end, and we get a range of options to play with. The B550-E Gaming is the more expensive of the bunch, at $280, although it is one of the few boards to offer x8/x8 functionality with its PCIe slots. The use of this configuration isn’t so much for gaming (despite the name), due to lack of SLI support, but it does enable a good setup for a machine based around GPU compute or add-in cards, like RAID cards, or additional PCIe x4 NVMe drives.
ASUS’ design philosophy this time around involves a similar corner to corner 45-degree line scheme to a lot of other different brands, however in parts ASUS pushes this to a more dot-matrix style design. We still get that ROG font on all the words though.
For features, the B550-E Gaming has a large rear panel cover that covers only the rear panel rather than the full audio section, and this covers over the heatsink for the power delivery. There are two heatsinks here, like most boards with high-end power delivery, but there does not seem to be a heatpipe between them for this board.
The socket area has access to four 4-pin fan headers within easy reach, three of which are just above and to the right of the socket. The CPU is powered by an 8-pin and a 4-pin, and the board has four memory slots with single sided latch arrangements. Down the right hand side of the board is a 4-pin LED header, a 24-pin ATX power connector, a USB 3.0 header, a Type-C header, and six SATA ports.
For the PCIe area, as mentioned the two main PCIe slots both come from the CPU, with x16 or x8/x8 connectivity at PCIe 4.0 bandwidth, due to the use of PCIe switches. Both of the main PCIe slots have extra reinforcement, and above the first PCIe slot is a PCIe 4.0 x4 M.2 slot, with its own heatsink. This isn’t connected directly to the chipset heatsink, however the second M.2 slot (a PCIe 3.0 x4 from the chipset) is connected. The final full-length PCIe slot is a PCIe 3.0 x4 from the chipset as well.
Along the bottom of the board is a 2-digit debug, two 4-pin fan headers, two RGB LED headers, two USB 2.0 headers, and the front panel headers. The audio codec on the left, ASUS’ custom S1200A codec, gets the SupremeFX treatment.
On the rear panel there is a 2.5 gigabit Ethernet port (Intel I225-V), a DisplayPort, a HDMI video output, two Type-A USB 3.2 Gen 2 ports, one Type-C USB 3.2 Gen 2 port, four USB 2.0 ports, one USB 2.0 Type-C port for audio, audio jacks, a BIOS Flashback button, and an Intel AX200 Wi-Fi 6 module.

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".
