Your Xbox 360 console has an external fan-assisted
power supply unit (PSU). The PSU has a hard-wired direct-current (DC)
power supply cord that attaches to the console and an alternating-current (AC)
power cord that attaches to the wall socket.
Power supplies are designed to be used only in the region where they are sold. Do not try to use an Xbox 360
power supply that was built for a region that has different
power requirements. Do not use an unlicensed accessory, such as a non-Microsoft replacement
power supply or any accessory that plugs in between the Xbox 360 console and the
power supply.
There are several versions of the Xbox 360
power supply. Depending on your Xbox 360 console’s
power requirements, the console package may have included a 203-watt
power supply, a 175-watt
power supply, or a 150-watt
power supply.
The connector on the end of your
power supply is keyed to fit into Xbox 360 consoles with which the
power supply is compatible. If the
power supply cord will not plug into your Xbox 360 console, make sure that the
power supply is the correct kind for your Xbox 360 console.

Warning about non-Microsoft devices that plug into the console power socket
Microsoft does not license any non-Microsoft accessories that plug into the Xbox 360s
power socket. Use of any accessory other than the standard Xbox 360
power supply may damage your console and void your console warranty.
Power supply electrical safety
To connect the power supply to your Xbox console: | 1. | Fully insert the power supply cord into the Xbox 360 console. |
| 2. | Firmly plug the AC power cord into the power supply until the plug on the cord is completely seated. |
| 3. | Plug the other end of the AC power cord into the wall outlet. |
As with other electrical devices, failure to take the following precautions can result in serious injury or death from electric shock or fire or in damage to the Xbox 360 video game and entertainment system.
Select an appropriate power source for your Xbox 360 console: | • | Use only the power supply unit and the AC power cord that was included with your console or that you received from an authorized repair center. If you are not sure if you have the correct power supply, compare the model number on the power supply with the model number that is specified on your console. If you need a replacement power supply unit or AC power cord, contact Xbox Customer Support. |
| • | Confirm that your electrical outlet provides the same voltage (V) and frequency [Hz] of power as is indicated on the power supply. If you are not sure of the kind of power that is supplied to your home, ask a qualified electrician. |
| • | Do not 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. |
| • | Do not overload your wall outlet, extension cord, power strip, or other electrical receptacle. Confirm that these items are rated to handle the total current (in amps [A]) that is drawn by the Xbox 360 console (as indicated on the power supply unit) 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 prong. If the plug does not fit into your outlet, have an electrician replace the obsolete outlet. |
