[/img]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.
