Your Xbox One console has an external fan-assisted power supply unit (PSU). It measures 6.69 x 1.88 x 2.96 inches (approximately 17 x 4.8 x 7.5 cm). 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 into 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 cord
The PSU has a hard-wired, direct-current (DC) power cord that connects the PSU to the console.
The DC power cord is approximately 3 feet, 6 inches (1.1 meters) long.
A proprietary power connector is permanently attached to the end of the DC power cord. This connector is designed specifically for the Xbox One console power socket.
AC power cord
The AC power cord connects the PSU to the wall socket. The AC power cord is detachable from the PSU.
The AC power cord is approximately 5 feet, 9 inches (1.8 meters) long.
The end of the power cord that plugs into the PSU has two holes. If you use a power cord other than the one designed for your PSU, you may damage it or your console.
The plug at the end of the power cord that connects to your electrical outlet 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, a stove, 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 strip or surge protector that is overloaded. Plug your PSU directly into a wall outlet 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 cord into the console.
Firmly plug the AC power cord into the PSU until the plug on the cord is completely seated.
Plug the other end of the AC power cord into a wall outlet.
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 cord that were included with your console or that you received from an authorized repair center. If you need a replacement PSU or AC power cord, contact Xbox Support.
Make sure that your electrical outlet 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 cord, 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 grounded electrical outlet that accommodates the three-prong grounding plug. Do not remove the grounding plug. If it doesn’t fit into your outlet, have an electrician replace the outlet.
To avoid damaging the power cords and the power supply:
Prevent the power cords from being walked on.
Protect power cords from being pinched or sharply bent, especially where they connect to the power outlet, the PSU, and the console.
Don't jerk, knot, sharply bend, or otherwise abuse the power cords.
Don't expose the power cords to sources of heat.
Don't wrap power cords around the PSU.
Keep children and pets away from the power cords. Don't let them bite or chew on the cords.
When you disconnect the power cords, pull on the plug. Don't pull on the cord.
Don't let the PSU hang from either power cord.
If a power cord 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.
