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-I Gaming
The sole entrant into the mini-ITX sphere from ASUS, at least at the time of writing, will be the B550-I Gaming. In true ASUS fashion, this motherboard does things a little differently than most. One of the biggest differences is the use of a separate audio daughter board for 3.5mm jacks. This daughter board combines onto one add-in with the M.2 slot, but the motherboard also has a Type-C audio port on the rear panel, and bundles in a Type-C to 3.5mm converter.
ASUS is again going for an angled mesh look, with there being a sizeable heatsink over the power delivery that morphs into the rear IO cover, as well as what seems like the M.2 heatsink. The 8-pin power connector is in the top left corner, sufficiently out of the way (a common problem on ITX boards).
The board has three 4-pin fan headers at the top, next to RGB headers, followed by two single-sided latch DDR4 slots. Along the right hand edge of the board are a 24-pin ATX connector, a USB 3.2 header, a USB 3.0 header, and four SATA ports all angled outwards. This makes the first two easy to remove when locking connectors are used, but the two inside will be hard to remove.
The single PCIe 4.0 x16 slot is reinforced at the bottom, and above this is the add-in audio board and M.2 heatsink combination. There is an additional PCIe 3.0 x4 M.2 slot on the rear of the motherboard.
On the back panel there is a DisplayPort, a HDMI port, a USB 2.0 port, a BIOS Flashback button, three USB 3.2 Gen 2 Type-A ports, a USB 3.2 Gen 2 Type-C port, a 2.5 gigabit Ethernet port (I225-V), Wi-Fi 6 (AX200), audio from the S1200A custom codec with SupremeFX trimmings, and a Type-C audio output.

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
