The reality is that Sony has done a pretty good job here. We'll get to the metrics in a moment, but first impressions are certainly reassuring. On start-up, the hardware is exceptionally quiet, but as you progress into gameplay, volume and heat does start to increase. PS4 also draws a fair amount of juice too - 80W at idle on the front-end menus (the "PlayStation Dynamic Menu" to give it its proper name), 95W based on in-game video playback, and around 110-120W during gameplay - that's about 10-20W more than the first release of the "Slim" PlayStation 3. Curiously though, bringing up the menu system while in-game sees another leap in power draw - up to the maximum of 140W.
