Previous power supply sizes at launch, for comparison:
PS3 - 380W
Xbox 360 - 203W
PS4 - 250W
Xbox One - 253W
PS4 Pro - 310W
Xbox One X - 245W
PS3 is a bit of an outlier. While it had a 380W power supply, it rarely used more than 200W.
Xbox 360 E had a mere 115W PSU!
It's going to be interesting to see how people handle the new consoles. Series X and PS5 are both huge units, with 350W PSUs on board. So the warning signs are there; don't go stuffing them in to a tight media cabinet and then complaining about noise (or worse, overheating).
I wonder how Series S will stack up?
