Until just recently, if your Xbox One was not under warranty, obtaining a replacement power supply brick was impossible. After fan complaints, Larry “Major Nelson” Hryb confirmed on Reddit that the option to purchase an additional power supply has been added to Microsoft’s support website.
Owners can ship back their out-of-commission power supply and receive the new one for $35, or simply order a replacement for $50. The Xbox One must be registered on Microsoft’s site before purchase options become available. The Xbox Service webpage can be found here.
This is what Major Nelson had to say after fan’s complaints:
Hey gang, I have an update on this. I have worked w/ the Support team and we’ve enabled the option to purchase additional Xbox One power supply units via https://myservice.xbox.com
I have not had a chance to check it out myself yet – but the team just emailed me to let me know they have added that option to the online tool.
