The AMD B550 Motherboard Overview: ASUS, GIGABYTE, MSI, ASRock, and Others

For the launch of AMD’s B550 chipset, Biostar has a pair ready to go with an ATX sized model and micro-ATX sized option. Both under its Racing moniker with flashy looks and controller sets catering more towards entry-level models, and it’s possible we could see Biostar release the B550GTN mini-ITX mode at a later date, although Biostar hasn’t unveiled any details of this at present.
Starting with the larger and more premium of the pairing, the Biostar Racing B550GTA an ATX model which looks very intriguing on paper. The most contrasting features of this model include a Realtek 2.5 G Ethernet controller while opting for an old school Realtek ALC1150 HD audio codec. Also present are two M.2 slots, a pair of USB 3.2 G2 ports on the rear panel, and support for DDR4-4400 memory.
Focusing on the design, the Biostar Racing B550GTA has a black and light grey patterned PCB which resembles sun rays, similar to that on the Japan national flag. It includes a black power delivery heatsink which doubles up as a rear panel cover, while the chipset heatsink includes a Racing logo and has white contrasting lines. The board includes two full-length PCIe slots with the top slot operating at PCIe 4.0 x16 slot and the second slot locked to PCIe 3.0 x4. There are also three PCIe 3.0 x1 slots with a legacy PCI slot and is the only B550 model at present to feature this. For storage, Biostar is advertising two PCIe 4.0 x4 M.2 slots, but this is likely an error in the specifications and one slot will operate at PCIe 4.0 x4 and one at PCIe 3.0 x4. It also includes six SATA ports with support for RAID 0, 1, and 10 arrays. The B550GTA includes four memory slots with speeds of up to DDR4-4400, and up to a maximum capacity of 128 GB.
Over on the rear panel of the B550GTA is a pair of USB 3.2 G2 ports including a Type-A and Type-C, with four USB 3.2 G1 Type-A and two USB 2.0 ports. Biostar includes a pair of video outputs including an HDMI and DisplayPort output, a PS/2 keyboard and mouse combo port, as well as a Realtek RTL8125 2.5 GbE Ethernet port. Finishing off the rear panel is a Realtek ALC1150 HD audio controller which adds three 3.5 mm audio jacks.
The Biostar Racing B550GTA is a little bit of a mixed bag with some core features attributed to the B550 chipset including USB 3.2 G2 connectivity and official support for PCIe 4.0. The decision to combine a premium Realtek RTL8125 2.5 G Ethernet controller with an older ALC1150 HD audio codec. Biostar also isn’t clear in its official specifications about the validity of its M.2 slots, as it advertises two PCIe 4.0 x4 M.2 slots, but this is really unlikely to be the case. At present, Biostar hasn’t unveiled any information in regards to pricing.

But the new oculus stuff only uses 1 usb port, so that right there is a drop. I use 2 for keyboard and mouse, one for a wireless controller, and one for my HMD.Gigaplex - Tuesday, June 16, 2020 - link
"On that one I added a USB PCI card to get enough ports."That's not really helpful to the user who said they can't add in a card on their mITX system.

Must be nice to have no external hard-drives, I have 3 all needing their own USB 3 port, along with a Logitech dongle that runs both my mouse and keyboard, finally a Bluethooth dongle as my computer has none built-in. Yes I would need 6 USB ports (one open for USB sticks) just to keep even.consolessuck - Friday, November 6, 2020 - link
No, I have 3 usb ports on my laptop and i only use 1 for my mouse. As it turns out, the most amount of usb ports i use at once is two when i am making a wired data transfer with my mouse plugged in. Actually, I almost never transfer data to my phone with a wire, instead just sharing them via bluetooth. and considering i never make large data transfers to my phone, this works out just fine. as for a desktop, however, i'd like a minimum of 3 as i'll always have not only a mouse, but a keyboard plugged in all the time.taz-nz - Thursday, June 18, 2020 - link
The Asrock B550M Steel Legend has 8 port on the back:4x USB-A 3.1 ports
1x USB-A 3.2 port
1x USB-C 3.2 port
2x USB-A 2.0 ports
And you still have two USB 2.0 internal header, plus two USB 3.1 internal headers.
So that allows you to have another
4x USB-A 3.1
4x USB-A 2.0 ports.
so that's 16 Ports
Now if you like me and need Internal USB 3.2 USB-C header, you can use the PCIe 3.0 x2 m.2 slot to add one of these:

or if you want two more USB 3.1 internal header you could add one of these:
https://www.delock.de/produkte/G_62843/merkmale.ht...
So if you can live without a second m.2 slot you have four more USB-A 3.0 ports.
That gives you 20 USB ports without giving up a PCIe slot.

oops, just noticed you said mITX not mATXdesii - Tuesday, June 16, 2020 - link
Do any of these motherboards support ECC RAM (either buffered or unbuffered)?drSeehas - Wednesday, June 17, 2020 - link
Socket AM4 CPUs support only unbuffered RAM.PixyMisa - Wednesday, June 17, 2020 - link
I did a quick look on ASRock's site, since they're pretty good on ECC support, and every B550 board I checked lists ECC as supported.Samus - Tuesday, June 16, 2020 - link
I think AMD screwed up here with pricing their platforms appropriately. I understand the push for PCIe 4 but they can't have average motherboard prices hovering between $200-$300. There has to be $100 motherboards to be taken seriously especially by OEM's if they want 4000 parts to become mainstream.But maybe they don't...maybe they plan to milk the 3000 parts for a few years. After all, there isn't much reason not too. They have no competition from Intel in the budget segment right now.
