The SSD enclosure has also changed in this new PS5 mode. It no longer has a PCB through the entire length, and instead has exposed metal. It’s not immediately clear why Sony has changed this particular part of the PS5 design, but Evans speculates it could help improve heat dissipation.
All of these changes might add up to some real world benefits for the PS5. Evans claims this new PS5 model pulls around 20-30 watts less during gaming, while still delivering around the same amount of noise and heat output.
