PSU replacement connector cable differences

Unfortunately Sony likes to release many different internal revisions of their consoles where they change only minor things. They look the same from the outside but have slightly different model numbers. You can only replace the power supply in your original console with the same model power supply.

The new one being noisy does not surprise me too much, see this quite often with PS4 consoles. Typically a result of either dust buildup in the heatsink, dried up thermal paste, or both causing the console to run hot and run the fan fast. It isn’t typically too bad to get the console apart to clean the dust out, if you are comfortable with trying to take the thing apart further I would recommend doing that.
