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-F Gaming + Wi-Fi
The B550-F Gaming is a cheaper variant of the B550-E Gaming – significantly cheaper in fact, almost $90 if we consider the non-Wi-Fi version of the B550-F ($190). For that cost difference, the PCIe configuration is a simple PCIe 4.0 x16 rather than a bifurcated design, we lose a USB 3.2 Gen 2 port on the rear panel, and it uses 12 phases for the CPU rather than 14. There’s still the same 2.5 gigabit Ethernet, still the same SupremeFX audio with dual amps. It just goes to show how much adding bifurcation to the B550-E ($280) ends up on the final cost of the board.
The difference between the B550-F ($190) and B550-F Wi-Fi ($210) is $20, with the only difference being the use of the ASUS AX200 CNVi module and bundled antenna.
As mentioned, this board has a 12+2 phase design, with the power delivery heatsinks coming in two parts without a connecting heatpipe. The heatsink on the left is part of the rear panel cover, which has additional LEDs inside. The CPU is powered through an 8-pin and 4-pin, and the socket has four 4-pin fan headers within easy reach.
The board uses single sided latch memory slots, and to the right of these we get the 24-pin ATX power connector and the USB 3.0 header. Below this is a set of 6 SATA ports.
On the PCIe front, we start with a PCIe 4.0 x4 M.2 slot which comes with its own heatsink, followed by the PCIe 4.0 x16 slot from the CPU that has additional reinforcement. The chipset heatsink is to the right, which sort of connects to the bottom M.2 slot, which is a PCIe 3.0 x4 design from the chipset. The final full-length PCIe slot is a PCIe 3.0 x4 from the chipset.
The audio on the board is ASUS’ custom S1200A audio codec, with SupremeFX trimmings and dual amps. Along the bottom of the board we have a Thunderbolt header, two RGB LED headers, a Clear CMOS header, a thermocouple header, two 4-pin fan headers, and two USB 2.0 headers.
On the rear IO there is a clear CMOS button, two USB 2.0 ports, four USB 3.2 Gen 1 ports, a Type-A USB 3.2 Gen 2 port, a Type-C USB 3.2 Gen 2 port, a 2.5 gigabit Ethernet port (Intel I225-V), a DisplayPort, an HDMI video output, Wi-Fi antenna (on the Wi-Fi version), and 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.
