Your Xbox One console has an external fan-assisted power supply unit (PSU). It measures approximately 17 x 4.8 x 7.5 cm (6.69 x 1.88 x 2.96 inches). Note that the PSU has the same basic design in all countries. There are no dimensional changes between the 100-110V, 220-240V and 100-240V versions.
Important Microsoft does not license any non-Microsoft accessories that plug in to the Xbox One console's power socket. The use of any accessory other than the standard Xbox One PSU may damage your console and void your console warranty.
PSUs are designed to be used only in the regions where they are sold.
Don't try to use an Xbox One PSU that was built for a region that has different power requirements.
Don't use an unlicensed accessory, such as a non-Microsoft replacement PSU, or any accessory that plugs in between the console and the PSU.
Don't use the Xbox One external PSU outside the country where it was sold. If you use the PSU in a different country, it or your console may be damaged, and the warranty may be invalidated.
The Xbox One PSU contains an internal fuse that helps protect your console from voltages that are too high and power surges. However, the PSU is a sealed unit. Therefore, you can’t replace the internal fuse.
DC power cable
The PSU has a hard-wired, direct-current (DC) power cable that connects the PSU to the console.
The DC power cable is approximately 1.1 metres (3 feet, 6 inches) long.
A proprietary power connector is permanently attached to the end of the DC power cable. This connector is designed specifically for the Xbox One console power socket.
AC power cable
The AC power cable connects the PSU to the wall socket. The AC power cable is detachable from the PSU.
The AC power cable is approximately 1.2 metres (5 feet, 9 inches) long.
The end of the power cable that plugs into the PSU has two holes. If you use a power cable other than the one designed for your PSU, you may damage it or your console.
The plug at the end of the power cable that connects to your plug socket can be one of several types. The plug type depends on the country and region where you purchased your console.
Power supply placement, temperature and noise
To provide sufficient cooling, the Xbox One external power supply uses a built-in fan to blow air through the PSU.
The PSU fan automatically starts when you press the power button to start your console.
Typically, the fan makes a "whirring" noise.
When your console is in energy-saving mode, or when it’s disconnected from the PSU, the fan doesn’t operate.
If your console is in Instant-On power mode, the PSU is still on and the fan will spin.
The speed of the fan increases or decreases when the temperature of the PSU changes. If the fan speed changes, the "whirring" noise that the fan produces increases or decreases.
To help the power supply operate efficiently and safely, follow these precautions:
Don't block any ventilation openings on the PSU.
Don't put the PSU on a bed, a sofa or any other soft surface that might block the ventilation openings.
Don't put the PSU in a confined space, such as a bookcase, a rack or a stereo cabinet, unless that space is well-ventilated.
Don't put the PSU near any heat source, such as a radiator, a heat register, an oven or an amplifier.
Don't stack other electronic devices on top of the PSU.
Make sure that the PSU is positioned horizontally and lays flat on the four rubber pads on its base.
Note If the PSU is making excessive noise, you might have a power board or surge protector that is overloaded. Plug your PSU directly into a wall socket and see if the problem persists.
Power supply electrical safety
To connect the PSU to your Xbox One console, follow these steps:
Fully insert the DC power cable into the console.
Firmly plug the AC power cable into the PSU until the plug on the cable is completely seated.
Plug the other end of the AC power cable into a wall socket.
Important As with other electrical devices, failure to take precautions can result in serious injury or death from electric shock or fire. An incident can also damage your Xbox One video game and entertainment system. Appropriate precautions include:
Selecting an appropriate power source for your console.
Using only the PSU and the AC power cable that were included with your console or that you received from an authorised repair centre. If you need a replacement PSU or AC power cable, contact Xbox Support.
Make sure that your electrical socket provides the same voltage (V) and frequency [Hz] of power as is indicated on the PSU. If you’re not sure of the kind of power that is supplied to your home, ask a qualified electrician.
Don't use non-standard power sources, such as generators or inverters, even if the voltage and frequency appear acceptable. Only use AC power that is provided by a standard wall outlet.
Don't overload your wall outlet, extension cable, power strip or other electrical receptacle. Confirm that these items are rated to handle the total current that’s drawn by your console (as indicated on the PSU), and by any other devices that are on the same circuit.
Use a properly earthed electrical socket that accommodates the three-prong grounding plug. Do not remove the grounding plug. If it doesn’t fit into your socket, get an electrician to replace the socket.
To avoid damaging the power cables and the power supply:
Prevent the power cables from being walked on.
Protect power cables from being pinched or sharply bent, especially where they connect to the power socket, the PSU and the console.
Don't jerk, knot, sharply bend or otherwise abuse the power cables.
Don't expose the power cables to sources of heat.
Don't wrap power cables around the PSU.
Keep children and pets away from the power cables. Don't let them bite or chew on the cables.
When you disconnect the power cables, pull on the plug. Don't pull on the cable.
Don't let the PSU hang from either power cable.
If a power cable or PSU becomes damaged in any way, stop using it immediately and contact Xbox Support for a replacement.
Unplug your console during lightning storms, or when the console is not being used for long periods of time.
