Why Sony Made Sure The PS4’s Power Consumption Was Under 250 Watts
It’s always interesting to hear what the engineers behind a piece of technology have to say about the design process, especially when it comes to our beloved consoles. There are so many variables that these people consider and often many intricate decisions made to achieve a single outcome.
In this case, one of the more fascinating design decisions was recently explained by Sony Computer Entertainment Engineering Director Yasuhiro Ootori during a technical lecture at the INTERNEPCON Japan trade show in Tokyo.

That is, the matter of the PS4 console’s power consumption and the targeted figure of 250 watts.
Yes, the word is that Sony’s engineers were specifically instructed to keep the PS4′s power consumption below 250 watts, and Ootori-san emphasised the significance of that decision. While you might possibly believe that it was to limit the heat or reduce the electricity used, those weren’t actually the main reasons.
Ootori-san explained that 250 watt is considered by safety regulations to be the upper limit that allows for the use of a two prong power cord. If the PS4 were to use 250 watts or more, Sony’s console would have instead required a three prong power cord, and naturally that means a three pin power inlet on the back of the PS4 as well. Since that sort of connector is larger in size, it would have negatively impacted Sony’s drive to make the PS4 as compact as possible.
This ensured that Sony put its best designers hard at work to make sure that the console would be as power-efficient as possible in order to maintain its consumption under 250 watts.
Below you can check out a picture of the PS4′s power source without its shell on, provided by Ifixit, and you’ll see that the power inlet is very small which contributes to saving space.
