Specs state a 2 W "base" difference:
RB5009UG+S+IN Max power consumption without attachments 14 W
RB5009UPr+S+IN Max power consumption without attachments 16 W
It doesn't sound as a lot, even if it can be read as "an increase of almost 15%" it remains 2 W.
How would the power adapter behave?
The first comes with a 24V1.5A power supply suitable for the stated max consumption of 25 W, the second comes with a 48v2A (PoE) power supply that can evidently bear the (unstated) 25/27? W max and has some 70 W available for other devices (but some excess heat production, if any, is moved to where the mains outlet is and in that the PoE power supply is more flexible in placement).
The math is strange, in the second, if max power is 150W and 130 of them can be used for PoE out only 20 W remain (in theory) for the device itself, which is coherent with the 20W of "reserved power" stated for cases of not enough power for the PoE devices and their shutdown based on priority.
