Best answer: Almost certainly the Xbox Series X has an internal power supply. While we don’t have official word, the figure-8 power port and our own information points to an internal power supply.
Cooling technology has improved generally over the years, with Microsoft itself investing heavily in cooling and power-optimization methods for both its Xbox consoles and its Surface computers. The Xbox One S and X both have internal power supplies, which regulates power from your wall socket to your console.
In the leaked photographs of the Xbox Series X, we got a glimpse of the ports on the back of the console, and we can see a standard figure-8 style power socket similar to what’s offered in the Xbox One S and X, as opposed to the 3-pin socket on the original Xbox One from 2013. We’ve confirmed with a few sources that the Xbox Series X does indeed have an internal power supply, as you might expect.
We’ll likely have some confirmation from Microsoft sooner, rather than later, but it’s fair to expect that there will be no external power supply brick with the Xbox Series X, keeping your playspace tidy.
