Power Usage

There’s a lot of performance on tap in the Xbox One X, which never comes with no strings attached. Like the Xbox One S, the APU inside is built on TSMC’s 16 nm FinFET process, which should help keep power usage under control. In addition, the Xbox One X is outfitted with a power supply that Microsoft equates to an 80 Plus Gold unit, which means it should be 90% efficient at 50% load with a 115 V source, and there shouldn’t be too much extra power wasted from the PSU converting AC voltage.

There’s several scenarios we tested for power usage:

Off – Xbox One X is powered off in Energy Savings mode, which means standby mode is disabled.

Standby – Xbox One X is powered off in Instant-On mode, which allows background updating and voice activation enabled (if supported).

Idle – Ethernet connected, no disc in the drive, system idling at dashboard.

Load (UHD BD Playback) – Ethernet connected, UHD Blu-Ray disc in the drive playing Planet Earth II, compared to The Hobbit on Blu-Ray on the original Xbox One.

Load (GoW4) – Ethernet connected, no disc in the drive, playing Gears of War 4 in UHD/HDR.

Load (The Wolf Among Us) – Ethernet connected, no disc in the drive, playing The Wolf Among Us in FHD SDR.

We’ve been able to compare against the original Xbox One, although not the S model as we didn’t have one on hand. The Wolf Among Us was chosen as an older game which caps at 1080p and SDR, and Gears of War 4 shows the power draw at full 4K HDR rendering. The comparison against the original for this game will of course be for the 1080p version though, since that’s the max it supports.

Power Consumption Comparions
Total System Power Energy-Saving Instant-On Idle Load (UHD BD) Load (GoW4) Load (The Wolf Among Us)
Xbox One < 2W 14.2W 53W 80W 107W 102W
Xbox One X < 1W 10W 56W 64W 172W 101W

As with the original Xbox One, when Instant On is disabled, the console is practically fully off. There’s a small amount of draw, but overall, not very much. Most people that use the console are going to likely want it in Instant On mode though, so games and the console can update while the system is off, as well as to provide a much quicker startup time, and games can remain loaded in RAM. In Standby mode, power draw is reasonable at 10 W, which is lower than the original console when it first launched. It’s still a fair bit of power, but when you factor in that it needs to keep 12 GB of GDDR5 memory powered up (among other things), it is not unreasonable to expect this amount of power draw.

Idling at the dashboard draws around 55 W, and to add to that, most non-gaming tasks don’t add very much to this total, if any. If you’re using your Xbox to passthrough HDMI from a cable box, it will take this same power draw. Maybe this would be an impossible pipe dream, but it would be nice to see the Xbox One also pass through HDMI when it is in Standby mode.

Playing back a UHD Blu-Ray (standard Blu-Ray on the original Xbox One) was a tiny bit higher than idle, which is good to see. Some of the draw would be the disc drive itself, but a lot of the playback would be offloaded to fixed function hardware in the media block so it’s not surprising to see it so close to idle.

Clearly gaming on older Xbox One games is not much of a chore for the Xbox One X, since the power draw is only about 50 W over idle. But, when gaming with an Xbox One X Enhanced title, such as Gears of War 4, the power draw jumps significantly to 172 W as the peak observed. This is quite a jump over the original console, and makes the cooling system, which is barely audible even under these loads, even more impressive. Compared to a high-end gaming PC though, the power draw is quite a bit less.

    "and an IR output, which would need to be paired with an IR cable if you want the Xbox to control your TV or cable box."

    Not true! I replaced an OG One + Kinect with a One X and found out the IR receiver on the front, is also a blaster! I am able to have my devices turn on/off automatically with the console, and control the volume with my Xbox media remote.

    Still wish it was HDMI-CEC, though.

    To be honest, I, as almost a lifelong gamer, am really disappointed in the new console. I mean, it's basically the same Xbox One, only with unnecessary secondary features and hardware that's barely any better.

    I don't dislike it, but i really don't see the point in making it.

    Wait wolf among us had frame drops on one x really that game is 4 years old and is also available on android and one x was not able to play it smooth.Maybe its the optimisation . Reply

    I bought a Canadian version of the One X. Should I use a step down transformer if playing in a different zone where power is 220v?? Reply

    Bought an Xbox One X at launch, really happy with it, especially with the costs of building a gaming PC (though prices are now starting to creep down).

    Looking forward to Scarlet (or Scarlett) the next round of Xbox consoles, as Phil Spencer said were deep in development at this past E3.

    There's another flaw with the Netflix app: it forces 60fps instead of 24fps, causing very subtle but still noticeable choppiness. Once again, this appears to be Netflix's fault as Microsoft put a facility in the Xbox One to allow apps to automatically switch to 24fps when required, and they've allowed third party apps to take advantage of this which is why every other app on the Xbox One uses 24fps when appropriate.

    Netflix evidently don't give a damn about people using their apps on consoles. It's almost like their CEO is a member of the PC Master Cringe crowd or something.
