Budget and most reliable mobo for AM4 (AMD ryzen 2200g)

[fastshot]

Hi people,
It's my first PC building and I'm going crazy because I know nothing about that! I've red the guide but I've something to ask you anyway

My goal is to build an office PC with very low power consumption (200W max) but great reliability along time, I mean I want no problems by the motherboard I'll get for the next 10 years (at least). I'll only upgrade ram but cpu and mobo will be inside for the longest time possible, I mean until their obsolescence. Moreover no dedicated graphic cards and a 7.2k sata hdd within a 2 fans case.

I'll get an AMD Ryzen 2200g because my budget is not so big and now I've to choose the motherboard and the budget is 130 bucks so not big at all. As we know the socket is AM4 and chipsets are: X470, X370, B450, B350, A320, X300, A300. A friend of mine says the best solution for me is B450 because my aim is neither gaming nor OverClocking so it's the best choice quality/price/goal for me. Another friend of mine says to get the X470 because it's the top quality chipset of all am4 mobo brands, nevermind if it's for gamers and OC-ers, it's the most reliable choice for the long time because it's built better and he says I can get a X470 mobo for around 100$, then he started talking about... phases, vrm, bios and other things that were arab for me!

So what AM4 chipset and brands and models can you suggest for a long time reliable motherboard under 130$?

B450 for sure. The 3xx series motherboards MIGHT still have a BIOS incompatibility. For an "office" maching a B450 will be just fine. I chose this one -- https://www.asrock.com/MB/AMD/B450M%20Pro4/index.asp to build my Linux server.

Both of these will be more then enough for you

sorry for the delay

i saw the specs of each mobo and i'd like to ask you these:

- asus Prime B450M-A/CSM. i'm in trouble getting it here in europe so i'd want to know if the version without CSM would be reliable like it or not (just asus Prime B450M-A). i've red this on CSM but i didn't understand so much, can you tell me the advantages of CSM?

- i saw the asus and asrock mobos support ddr4 memory until 3200 instead the msi reaches 3466. will this be an important difference for me?

- in general, as i red around the web, there're no differences about reliability between atx and micro-atx mobos, aren't there? you suggested me only micro-atx mobos only to save some money and because i'm not interested in pcie's, didn't you?
