I believe the power usage is actually higher than 65W with the higher end CPUs. The review shows that at max load, the system with the Ryzen 5 is pulling in 68W, and that is assuming that you are not connecting additional components to the USB ports, other than mouse and keyboard. So a 90W power adapter is actually the best bet. But considering the 90W and the 135W is only 2 to 3 bucks difference, no reason to go with the 90W.
Anyway, I figured that my order did not go through for some strange reason. I saw the confirmation screen after completing the credit card OTP screen, but was thinking why I did not get an email to confirm the order. When I checked "my orders" in my account, I don't find that order. Strange...
