It was purchased for a mini ITX build. For the price of €130 at which it was purchased (and at the time it was purchased, when motherboards were starting to become scarce and sold at higher prices), it is considered a good value for money, considering what it offers in its category.
However, it should be noted that regardless of the price, objectively it is inferior to the ATX motherboards in the category (b550), due to the VRM. It would not be wise to pair it with something more powerful than a 5600-5600x. (Not that it doesn't support higher processors. It's just that it definitely loses performance from dynamic overclocking due to the limitations of the VRM.)
To fit such a processor (R7-R9) in this size (m-ITX), the budget for a motherboard that will allow it to perform adequately (at the time of purchase) is around €200, while for an ATX it is less than €160. So, at €130, yes, it is a very good choice if you know that it also sacrifices other things due to its dimensions and is limited to 2 RAM slots, 1 M.2 slot (gen4), and 1 PCI-E slot (fortunately also gen4).
If you are generally looking for an AM4 motherboard, then it is better to stay away and spend an additional €30 for the Aorus B550, for example (full-sized ATX - not m-ATX). It is a significant amount, but you get what you pay for.
Everything is fine so far, I have it in a Dan Case A4. It has few USB ports which doesn't bother me. I haven't tried the WiFi and Bluetooth, so I don't have an opinion.
Very good choice..you do lose some features of the more expensive b550, but the price difference with the second cheapest is too big not to take it..value for money..everything works fine
With AMD's announcement, the B550 socket will support the upcoming zen3 processors. This motherboard will offer good upgradability in the future. Everything works perfectly, including WiFi, Bluetooth, etc
