Fits perfect with no issues
Had a board given to me, I believe it is a asus b570 plus Wi-Fi. It had no backplate or mount. This worked perfectly, included everything I needed and the factory ryzen heatsink fit like OEM. Feels strong, no bending on the clips when I secured it. Good buy.

DID NOT FIT AM3+, NOR AM4
I'm not wasting my time and going around snapping photos for you. They're too wide and short. The bold/screw-hole pattern doesn't match, or line up, at all. I ordered a couple of these and they didn't fit AM3+, nor AM4 which would be the same at any rate. AMD has been using the same size backing plate backing plate for at least 15 years. I've been building and repairing computers for about the same amount of time. I couldn't tell you what these brackets fit. It's not intel either. AM2 all the way through AM5 should at the very least have the same bolt pattern.
