The AMD B550 Motherboard Overview: ASUS, GIGABYTE, MSI, ASRock, and Others
by Dr. Ian Cutress & Gavin Bonshor on June 16, 2020 11:00 AM ESTASRock B550 Steel Legend
The Steel Legend series of motherboards has been around for a couple of generations now, focusing more on an aesthetic more towards white and greys, as if the motherboards themselves were using stainless steel on the heatsinks. The B550 Steel Legend in this case uses heatsinks on the power delivery but they do not have a heatpipe at this price point, but we do get some extended M.2 armor from the chipset. The motherboard PCB looks very busy in this styling.
There is some RGB LEDs, on the rear panel cover and on the chipset, and there are two RGB headers on the board in the top right and bottom middle. The socket area has access to five 4-pin headers in easy reach, and like the B550 Taichi, we have four DDR4 slots with single sided latches.
On the right hand side of the board is a USB 3.0 header, a Type-C header, six SATA ports from the chipset, and a two-digit debug. On the bottom there are more fan headers, two USB 2.0 headers, and pads where power/reset buttons should be, perhaps on a different variant of this motherboard.
The B550 Steel Legend only has a single main PCIe 4.0 x16 slot from the CPU, with additional reinforcement, and there is an additional PCIe 3.0 x4 slot from the chipset. The audio for this board is beefed up, with the Realtek ALC1220 codec being paired with an NE5532 amp. The M.2 slots on this board are for one PCIe 4.0 x4 drive and one PCIe 3.0 x2 drive – there is an additional M.2 Wi-Fi slot in the middle.
From left to right, on the rear panel we get a DisplayPort, HDMI, a combination PS/2 port, two USB 3.2 Gen 1 ports in blue, four USB 2.0 ports, a Type-A USB 3.2 Gen 2 port, a Type-C USB 3.2 Gen 2 port, a Realtek RTL8125BG 2.5 gigabit Ethernet port, spaces for the Wi-Fi antenna, and the audio jacks.

Right now, it seems more like B for Backordered. They may be priced a bit high, but the demand still seems to be there.yannigr2 - Tuesday, June 16, 2020 - link
This is a great article but it needs a follow up with a table for every motherboard explaining how they use the PCIe lanes in conjunction with M2 and SATA slots. It seems that motherboard makers are totally f up(sorry for the expression) the more reasonably priced models in that area.romrunning - Tuesday, June 16, 2020 - link
Does anyone know if the boards that have the Intel i225-V are shipping with the fixed hardware (v2)?R3MF - Tuesday, June 16, 2020 - link

Wow, another broken Intel NIC? I wish motherboards would stop using Intel NICs.mooninite - Tuesday, June 16, 2020 - link
After Googling it looks like v2 is not fixed either... a v3 is coming out. Time to buy Realtek.romrunning - Wednesday, June 17, 2020 - link
Which is hilarious - I remember when Realtek was the worst when it came to NICs, and Intel/3Com was the standard. :)WaltC - Wednesday, June 17, 2020 - link
Yes, indeed...;) My x570 Master has an Intel gigabit & a realtek 2.5gb. It's amusing because my interface is an EWAN that tops out at 1Gb, but I thought I'd try the realtek just to see and then I forgot about it...;)...Seems every bit as stable as the Intel--still on it, lol...;) Six of one, half-dozen of another.eastcoast_pete - Tuesday, June 16, 2020 - link
Thanks Ian and Gavin! One question, related to a likely use case for B550 mini ITX or mATX Boards: is it true that AMD will, at least initially, limit Ryzen 4000 APUs to OEMs? If that is so, I am definitely not interested in a B550 board in those form factors, and I don't think I am alone here. An answer is appreciated - thanks!mrvco - Tuesday, June 16, 2020 - link
I'm just here for the Next mini-ITX boards. I'm liking the Aorus Pro AX quite a bit.
