XB1X has as many USB ports and more ports overall. If both consoles have similar hardware, use around the same amount of power, and have about the same amount of ports, then their PSU's should be fairly similar as well, yet the XB1X has more performance and it's PSU based on it's peak rating is about 20% lower than the Pro PSU. Some of this could be PS wanting extra longevity, and also the XB1X 'hovis method' power management system they have in place, but some of it is no doubt PSU efficiency rating based on the overall XB1X capabilities. Now whether the efficiency difference for the PSU itself is really 10% or 20% we don't know exactly, but it still proves the point that the PSU design and quality matters.

The point was about how much power the Subor is pulling from the wall, and what that means compared to the existing consoles and where they can go in the future. Well if the existing consoles have more efficient power supplies, then more of that power is going into actually feeding the hardware and not being wasted in the PSU conversion process. With a more efficient PSU, instead of pulling 185 watt from the wall, the Subor could possibly pull 150 watts instead let's say, which would mean headroom for extra hardware performance to bring it back up to 180w, with a more efficient PSU. It's also possible the Subor has a high end high efficiency PSU and it's totally maxed out, but we don't know that, and that's typically not the case as PC's get cheaper.

The Xbox One X's PSU is an efficient unit that is 90% efficient at 50% load, I would be surprised if the Playstation 4 Pro even comes near that.

Especially considering that the very recent 7200 Pro model has had some sort of change to the PSU. Even though when tested, all Pro models pull very close to the same amount of power from the wall. The first 2 iterations had the 3 prong power plug, and the new model has the dual prong like all PS4's have. I remember reading an article way back, that the PS engineers were pushed to keep the supply wattage down and efficiency up as much as possible so the two prong plug could be used. This was due to electrical safety standards of certain countries. The wattage they had to remain below to accomplish that was 250 watt, which was the exact size PSU they used with the first 2 iterations of PS4, before dropping down to 230 watt for the 1200 series. This leads me to believe the newest Pro model must have a PSU peak of 250w or lower now, which would allow them to use the two prong plug. So PS seems to have gotten rid of any overkill they may have had on the earlier Pro models, while also increasing the PSU efficiency considerably.
