PSU is fine and there is no reason you can't use that as the boot drive. I am using the same drive as my boot drive on my Ryzen build (Crosshair VI Hero). What stories have you read? Likely people who are doing it wrong.
The problems had something to do with the bios, it needed updates etc. before it reconized the ssd.
You can updatde the BIOS with just the CPU in there you don't need the SSD connected, and if thats the case that is not a big deal its simple. You should update it anyway. However I have serious doubts the BIOS needs an update to recognize an SSD, even an M.2
