got curious and did a bit of research on this .. for the most part I'm happy with it's "cousin" the Asus TUF gaming B550M MB though I thought I'd pass on a few things I learned the hard way.

I found myself grateful for the EZ Bios flash feature on the above mentioned MB after I found out the hard way (albeit with an AS Rock brand MB) that the bitter amazon complaints about MB's that don't support what they consider to be a "newer" CPU out of the box are very true.. I ended up having to return my MB and purchased the Asus MB I mentioned primarily for the EZ Bios flash function which allows you to update the BIOS without having the PC assembled and up and running, just plug the power supply into the MB, download the bios onto a usb thumb drive and hit the button on the MB itself to update the BIOS.

From what I can see this MB does not have the EZ Bios flash feature .. I know there are people who will argue that it's a newer MB out of the box that should support most CPU's but that's what people told me too in support forums about my AS Rock MB too and sure enough the worst case scenario came true and it flat out refused to cooperate with the AMD 7 5700X CPU I bought. I noticed some bitter amazon review complaints about this exact same problem so be aware of that when you buy the MB (though as usual amazon had an excellent return policy, just make sure you hang onto the box and packaging that came with the MB).

I'd also recommend snagging some paper coffee filters (strange but true, works great as a thermal paste remover without leaving thread "residue" on the CPU) and 90 percent rubbing alcohol which you can snag cheaply enough at a local walmart

https://www.walmart.com/ip/Equate.../276040459

and some arctic thermal paste also very cheap right now

https://www.amazon.com/gp/product...UTF8&psc=1

so if the worst case scenario does happen you can clean the thermal paste off more easily when you have to remove the CPU and return the MB to amazon. Honestly I've been told on various online support forums that it's best to use the arctic thermal paste instead of the pre-applied thermal paste on the CPU anyways, it will make removal of the CPU more easy in the future apparently the pre-applied stuff hardens to a rock like consistency sometimes.

I found myself curious as to whether or not plugging in one or two m2 drives (crazy cheap right now even the higher quality ones so definitely grab that) would disable any of the other 4 sata ports as is the case with some MB's.. not finding anything specifically stating that on the Asus documentation so maybe you get to have all 4 sata ports enabled and both m2 slots? Which would be really nice Smilie (yep there's crazy people like me who use ALL the sata ports for hard drive connectivity on their MB's).

Here's the documentation I was referring to

Also I've found the ASUS MB's to be a bit "finicky" when recognizing ram.. do yourself a favor and if you plan on getting 32 GB of ram do that right now, don't go the 16 GB route then add 16 GB more later on like I did even if it's exact same model make and manufacturer.

Even then you may have to plug one stick of ram in at a time, let the MB recognize the one stick, then plug the second one in and rinse and repeat if necessary until the MB recognizes it.. this was an issue with all three of my ASUS MB's that I purchased. Definitely read the pdf of the motherboard manual that I linked and make sure you're putting the ram in the slots that the manufacturer recommends too.

Asrock steel legend at 130$ looks like a much better board, I have a b450 and it's been great And looks damn good

Absolutely nothing special about this board. it's a B450M-A ii, removed the flashback feature and add WiFi.

https://pcpartpicker.com/product/...rd-b550m-k

You can't beat this for $75. 2 m.2, pcie 4, but only 1 fan header so grab some Arctic case fans that you can daisy chain or run molex to 4 pin.

https://pcpartpicker.com/products...rice&c=145

There are better options with bios flashback at around $100.

Asus makes these "Prime" motherboards that run hot. Please read reviews before buying - I bought a "Prime" and had to return it.

The Gigabyte B550m DSH3 AC isn't bad on Amazon either if you're looking to avoid Asus. They have is renewed for $90: GIGABYTE B550M DS3H AC (AM4 AMD/B550/Micro ATX/Dual M.2/SATA 6Gb/s/USB 3.2 Gen 1/PCIe 4.0/HMDI/DVI/DDR4/Motherboard) (Renewed) https://a.co/d/0IH8ip1

I got it new on Thursday for $90, sorry the new price went up, but I prefer Gigabyte after my ram issues on Asus boards. Pretty comparable features-wise to this asus.

The system is already built and working, first boot with ram profile enabled, no issues like I had with my asus b550 strix board.

I've built into the non-wifi version of this board. Great budget board but I ended up switching out to some ASRock board due to lack of USB 3.1 header and basic/limited RGB support. If you are looking for something flashy/feature rich this isn't it. I've built 2 PCs with this board for those that didn't care for those features and they've been happy with it.

I'm a big fan of the Prime series and have gotten three generations so far. Just the right balance for normal productivity users.
