The renowned ROG UEFI (BIOS) provides everything you need to configure, tweak, and tune your rig. It offers intelligently simplified options for newcomers to PC DIY, as well as comprehensive features for seasoned veterans.

When you're ready for a deeper dive into the configuration of your system, delve into the UEFI's Advanced mode and take complete control. Each section is intuitively organized, and a built-in search feature makes it easy to find the options you need. Advanced functions are coded with the intelligence to adapt to your settings, and when you're ready to take charge, parameters have the granularity to dial in performance just the way you want.

It works for my use case.

I recently decided to upgrade my older x470 motherboard and this was the option I decided to go with. The System it is now in did require a new windows product key as that activation went with the old motherboard (keep this in mind if your upgrading an old system). This motherboard was the better of the available choices at the time for a AM4 Socket setup. The only nitpick I have is the Asus fan control software was lacking in customizability for my desired control. Otherwise this board is a great option.

Needed a ATX mobo because my smaller mATX wasn't big enough to fit a network card and my graphics card, this fits perfectly in my case.

Read the manual online and research your use case before you buy

Reasons to buy

If you're building an ordinary gaming PC, I don't think you're giving up much over not buying X570,
If you're building an ordinary desktop PC, the build process won't have many surprises, if any
Captive screws on M.2 heatsinks
6 SATA ports
BIOS flashback
2.5G ethernet
No separate IO shield

Reasons not to buy
If you're not building an ordinary desktop PC and have specific needs you might have some quirks with the SATA ports when you're building, or not enough PCIe lanes with the B550 chipset
You can't have the 5th and 6th SATA port if you want to use the 2nd M.2 NVME slot

Adequate replacement when supplies are low

It's getting harder to find a decent b550 motherboard as most have been discontinued, these are still around in great numbers for some reason. I only ended up with one because I damaged my previous motherboard. No issues with bios or setup, all seems to be working well.

White colour scheme is kind of annoying, but the large plastic oi shroud can be removed for improved aesthetics.

great motherboard but with some problems

I just recently started to use this motherboard, and I have encountered some errors with the sound processing with the headphone jacks, as it is only outputing audio but not using the imputed audio in software like Discord. But I love the silver accents around the i.o. sheilding and the VRM chips, as I personally find them to be very tasteful. Also, I like the opt-in CPU fan option, as it eliminates the need for fan splitters for certain multifan coolers.

One of the better am4 options available from pb tech

I used this motherboard to replace another that stopped working. With AM4 options slim for the picking this was one of the better options available. It has the option of thunderbolt which is nice but is missing Bluetooth, wifi and built in front usb c header.
