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 B550M-HDV
Nearer the bottom of the ASRock product stack we get to the B550M-HDV, which is aimed at the more commercial pre-build markets and aims to offer what these markets might need. As a result it does away with the fancy styling and aims to give the bare essentials. That means no power delivery heatsinks, only two DRAM slots, no extra M.2, and only a 4-pin CPU power connector is needed.
The idea for these boards is that they will be put into systems that might be found in commercial units, like libraries, medical facilities, youth centers, that sort of thing. So there are only two fan headers around the socket for example. The power delivery is basic, we get a 4 phase design, and the two DRAM slots are still single side latched.
Moving clockwise around the board we get the 24-pin ATX power connector, a USB 3.0 header, and four SATA ports. The bottom of the board is the audio front panel header, a Clear CMOS header, a TPM header, a COM header, two USB 2.0 headers, another 4-pin fan header, and the front panel header.
The PCIe area consists of a single PCIe 4.0 x16 slot, without extra reinforcement. Beneath this is the PCIe 4.0 x4 M.2 slot from the processor, and underneath this is the chipset heatsink, which is the smallest chipset heatsink I’ve seen on B550 so far. On the left hand side of the board is the audio, where we have an updated ALC887 solution using PCB separation.
On the rear panel, we get two USB 2.0 ports, a combination PS/2 port, HDMI output, an analog D-sub video output, DVI-D, four USB 3.2 Gen 1 ports, a single gigabit Ethernet from a Realtek RTL8111H controller, and the audio jacks.

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.
