I'll subtract 65W from it then ...

Double it, that something one should do?

  Default TDP
  65W
  AMD Configurable TDP (cTDP)
  45-65W

I got these digits from
https://www.buildcomputers.net/power-consumption-of-pc-components.html
which is one of the first Google hits so I trust them for
now ...

As for upgrading that will be easy in this regard since I'll
read how many Watts on the box of whatever I get :)
