Is it possible for me to purchase a new Original Xbox one Power supply?/ If so where?

Yes.

If you contact official Xbox support at support.xbox.com/Contact-us they can assist you with that.

Hi

If it is the original Xbox One with the separate power supply (brick) then you will need to purchase a new power supply, If you own an Xbox One S or Xbox One X then you will just need to purchase a new power cable.

Hello JoeValero,

Thank you for bringing this issue to our attention. Sorry to hear about the power supply not working. The original Xbox One power supplies should be used only in the regions where they’re sold new. Don't use a power supply built for a region whose power
requirements differ from where you are. If you come back to the United States, we recommend purchasing a new power supply that is sold in the United States. We hope this helps!

Hi

With the original Xbox One you will need to purchase a new power brick however I don't believe you will be able to purchase one in the US. If possible if might be worth looking to upgrade to and Xbox One S or X as the internal power supply supports both
220V and 110V so all you would need to purchase is a new power cable when you arrive and you can then just connect the cable directly to the console.

I bought my Xbox one original in south africa but have moved to the USA, if I purchase a power supply in the USA will it work

Hello,

Xbox is saying it supports 100-240V 50/60Hz then this should be
OK to use in a country with a different voltage and all you will need
to do is obtain a suitable power cable.

If your purchasing an original Xbox One that had the separate
power supply then a new power supply will be required.
