Xbox One vs Xbox One S vs Xbox One X: differences

The quickest way to tell them apart is the power supply and the display output. The original Xbox One has an external power brick and isn’t listed for 4K or HDR. The One S and One X have internal power supplies and HDR, and the One X renders games in native 4K.

4K and HDR

Microsoft lists the One S, One X and Series X|S as the consoles for 4K and HDR. HDR10 is the default, and some apps also support Dolby Vision. On the One X, 4K content shows at native 4K and other content, such as 1080p games, is upscaled. Microsoft’s One X page describes 2160p frame buffers and 6 teraflops of GPU power. At launch in 2017, Microsoft called it “40 percent more power than any other console”. The One X also plays 4K UHD Blu-ray.

The original’s power supply

The original Xbox One uses an external, fan-assisted power supply, about 17 × 4.8 × 7.5 cm, with a fuse that can’t be replaced. It comes in region-specific versions (100–110 V, 220–240 V and 100–240 V), and Microsoft says to use it only in the region where it was sold new. The fan turns off in energy-saving mode. Microsoft doesn’t license third-party replacement supplies and warns they can damage the console and void the warranty.

Kinect

The One S and One X need the Xbox Kinect Adapter (sold separately) to use Kinect. For Kinect on newer consoles, see the Series X|S accessories page linked below.

One S power draw

In Microsoft’s Games Console Voluntary Agreement test, the One S draws 62 W in active gameplay, 27 W on the home screen, 11 W in sleep and 0.5 W in energy-saving shutdown.
