Types of 360 Power Adapters

There are three different wattage power supply units (PSUs) for the original Xbox console. Microsoft, which makes the Xbox 360, has made several versions of the gaming console that have different power requirements. The PSU's plug connector is keyed so that the cord will only plug into an Xbox unit that is compatible with that PSU. There is a sticker on both the console and the PSU that states the wattages for each. There is only one power supply unit type for the new Xbox 360 S.

PSU Versions
- The three versions of PSUs for the original 360 consoles are the 203-watt, the 175-watt and the 150-watt. The new Xbox 360 S console has only one PSU, a 135-watt. To verify you have the correct PSU, compare the 12v output number on the PSU to the 12v output number printed by the power socket on the console. The number on the power supply must be equal to or higher than the number on the console.
Cord Ends and Voltages
- The cord ends and voltages vary, depending on the country the consoles were manufactured for. Canada, Colombia and the United States all use 120 volts at 60 Hz, and Mexico uses 127 volts at 60 Hz. However, they all use the same type of cord end. Chile, on the other hand, has 220 volts at 50 Hz and utilizes a different cord end. Microsoft warns not to use PSUs outside the country where the power supply was sold. If you use the wrong PSU for the country you are in, you could damage the console and/or PSU and void your warranty. See Resource 1 for a complete list of voltages and cord ends for the different countries.
AC Power Cords and PSUs
- AC power cords are available with two-hole ends and three-hole ends. Only use the two-hole ended cord in PSUs with two-prong sockets. Use three-hole cords for PSUs with three-prong sockets. Using the wrong AC power cord may damage the console or PSU.
DC Power Supply Cords
- The direct current (DC) cord is permanently attached to the PSU. The end that plugs into the console's socket is keyed to fit only into compatible consoles. If it is the wrong PSU for the console, it won't fit into the socket. Refer to Section 1 to verify that your PSU is compatible with your console.
