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.

Looks like some nice mATX versions this round, nice!YB1064 - Thursday, June 18, 2020 - link
I was hoping to see a $75-$90 board.kenjiwing - Tuesday, June 16, 2020 - link
Fortunately, this component is a unique motherboard among B550 and well worth reading up on [add link].Needs to be edited.

There's a noise sensor which can adjust fan speed for maximum quietness with good thermals. Saw it on the KitGuruTech video. The noise sensor isn't there to spy on you though.PeterCollier - Wednesday, June 17, 2020 - link
The quality of the editing here is shit tier. Seriously, just run the articles through Grammarly before publication. It's free and it spots plenty of errors.Heavenly71 - Tuesday, June 16, 2020 - link
Sadly none of the mITX boards have more than 6 external USB ports. My old ASUS mITX has 8! And in really small mITX cases you can't add a bracket with more USB, because the two brackets are already used by the gfx card. Guess I have to wait for an enthusiast mITX board )-:damianrobertjones - Tuesday, June 16, 2020 - link
Or, just maybe, get a usb dongle with 4 ports?Mr Perfect - Tuesday, June 16, 2020 - link
That is disappointing. The number of USB devices people need to plug in can't be dropping, surely? I know I've got more now then even a year ago.rrinker - Tuesday, June 16, 2020 - link
Are they really going up? I have 2 USB devices plugged in to my system - a keyboard and a mouse. I occasionally plug a USB stick in one of the front ports to transfer files. My phone and tablet sync over wifi, they don't get plugged in. I have a charger behind my desk and a cable to charge them. My printer is on the network.The one place I DO need lots of USB ports is also the place where I have a small cube case machine, with no discreete GPU, because it doesn;t need one. On that one I added a USB PCI card to get enough ports. In addition to the keyboard and mouse, that machine is on my workbench where it connects to several electronic test instruments and I have multiple cabled for programming microcontrollers. I also have a USB microscope for board inspection. And then I have 3 more USB devices connected for my other hobby that shares the bench. Plus a front port kept free for USB sticks.
So the use case I have for more USB has the PCI slots open to add expansion cards, the use case where I have a discrete GPU eating up the slot space doesn't need an excess of USB ports.

I use 3 USB 3.0 ports just for my Oculus Rift
