I can't guarantee your Ryzen will be stable at that clock, or that your cooling will be sufficient, but I am confident you won't have power issues.
My actual PSU right now some might argue is only a notch above the VS; it is the newer CX-450M. That's not going to remain though; I just got the current machine online (not in my .sig yet) with what I had on hand. It's "real" PSU just arrived, a Seasonic 550W Focus. I may install it tomorrow or Tuesday, but with the system pulling so little power, I'm in no hurry.
