Outdated Product
Ultra-compact and well-featured 2020 mini-ITX motherboard with AMD AM4 socket and AMD B550 midrange chipset. It belongs to the models of the Asus Republic Of Gamers overclocker family, whose products are famous for their increased reliability and excellent overclocking potential. It is positioned as a product of the middle price category, designed to create performant gaming PCs. In addition to small overall dimensions (170x170 mm), it features impressive equipment and support for current versions of system/peripheral interfaces. Due to its small size, the Asus ROG STRIX B550-I GAMING motherboard can be installed in compact SFF, mini-ITX and microATX cases.

How to choose a motherboard?Motherboard is the main part of any computer. Here's how to choose the right one for work, play and entertainment
The board is excellent, so far I have never regretted choosing this particular model.
13 February 2021 
An extremely suitable motherboard, when I was choosing a Mini ITX, I chose it and didn’t regret it. It is important to note that there are analogues on the X570 chipset, but on the Mini ITX you will not notice the difference, except for heating, so I would recommend looking at the B550.
Updating the BIOS from a flash drive, the motherboard purchased upon release of the 5xxx series processors didn’t initially work with the 5900x, but in 10 minutes it updated directly from the flash drive from a non-functional state, and I didn't have to take it in for reflashing.
Cool VRM zone. There is a fan on it, but I've never noticed it turning on, even after running a Cinebench benchmark. Maybe if it runs longer, it will turn on, but it will definitely not be heard over the noise of the CPU cooler.
A bunch of overclocking features in the BIOS, thousands of presets, and some settings that I haven't seen in cheaper boards. In my opinion, all the tools you could wish for are provided.
Excellent overclocking, I didn't notice any overclocking limitations from the board itself, everything always comes down to the processor.
A bit lacking in fan headers, I wish there was at least one more.
No USB 2.0 header for the front panel of the case.
Installing RAM is very tight, the G.Skill Trident Z went in with a crunching sound, no space to spare, it took about 20 minutes to push it in without breaking anything. Uncomfortably forceful effort was required, the board was bending. Fit almost perfectly. But once in, it works excellently.
All these shortcomings probably stem from the Mini ITX format, nevertheless.
