Using an Xbox One's power cord for an Xbox 360

That wouldn't work but it won't hurt to try.

Hello Charles!

The Xbox One and the 360 Power Bricks are not interchangeable because they are different wattages/volts.

• A proprietary power connector is permanently attached to the end of the DC power cord. This connector is designed specifically for power sockets on Xbox One S and original Xbox One.

I'm sorry but I believe your best bet here would be to get the proper cable for the console. I would recommend trying your local gaming store or an online retailer.

Sounds like your Xbox 360 power supply is going out. I'd recommend trying to narrow down if it's your power cord that is failing or you Xbox 360 that is overheating. Recommend using a different power cord and see if your Xbox still fails to power on. Best
of luck to you!

Problems with your Xbox 360 console can sometimes be solved by making sure your power supply connections are firmly connected. Try these steps in the following order:

1. Turn off the console.
2. Unplug the power cord from the back of the console.
3. Unplug the power supply from the electrical outlet, and then unplug the short cord from the power supply.
   
4. Plug the power cord back into the console, then plug the power cord back into the electrical outlet and the power supply.
   
5. Make sure that all three power supply connections are firm.
6. Turn on the console, and check the light on the power supply.

Also remember that

• The power brick like the xbox itself needs to remain in an open space, and clutter free
  

• tampering with the Xbox can void the warranty as well as lead to banning.
