In Intel world, yes :) In AMD world it seems to be slightly better, cf.: https://images.anandtech.com/graphs/graph16220/119126.png The TDP is given in the labels whereas the actual max power consumption observed is in the diagram. It seems that for AMD systems, the most extreme factor observed there is 143.22/105 = 1.364, so you might take that or round up to 1.5 rather than factor 2 for AMD systems.

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 ...
The figures on that page for CPUs are misleading (they specify TDP range which is not much related to actual power draw anymore, see linked figure above). The remainder of the figures seems sensible. Some GPUs are also known to draw extreme peak loads (though usually that's only the "large" ones). SSD highly depends on the model. No need to argue for one general figure over the other. I think my SSD is specified 14W, but it is large and not the "newest" :) For RAM it seems that my figure is just a little too high and that your 3W are more correct in modern times. Nice to know :)
As for upgrading that will be easy in this regard since I'll
read how many Watts on the box of whatever I get :)

total:
(ceiling (+ 65 (* 3 3) (* 2 6) 19 (- 166.2 65) 3 2.8)) ; 212 W
with +30% wiggle room:
(ceiling (* 1.3 (+ 65 (* 3 3) (* 2 6) 19 (- 166.2 65) 3 2.8))) ; 276 W
IMHO this is too low a figure for the system being planned. I am pretty sure it _will_ run on a 300W PSU, BUT probably not stable for a long time and under high loads. HTH Linux-Fan
