Fonte original Xbox One, onde comprar?[Original source Xbox One, where to buy?]

As Njal has said you can find them on Amazon, for example here: Amazon

Você está perguntando sobre um bloco de poder? Se assim for, a Microsoft não fabricá-los mais. Gostaria de sugerir verificando Amazon e eBay para ver se você pode encontrar um.

[Translation - Are you asking about a power pack? If so, Microsoft does not manufacture them any more. I would suggest checking Amazon and eBay to see if you can find one.]

Olá Josue,

Infelizmente o Xbox 360 já saiu de linha a muito tempo. A lei brasileira só exige que a marca disponibilize peças de reposição enquanto o produto for comercializado. No seu caso, acho que o lugar com maior probabilidade de encontrar a fonte original é o

Mercado Livre.

Boa sorte em sua busca.

[Translation - Hello Josue, Unfortunately the Xbox 360 has been out of line for a long time. Brazilian law only requires the brand to provide spare parts while the product is marketed. In your case, I think the most likely place to find the original
source is Mercado Livre. Good luck in your search.]

Hi Josue,

Thanks for reaching out to us today. The best option available to find a power supply for the Xbox 360 would be through third party retail stores such as (Walmart, amazon, Ebay)

As we no longer manufacture any Xbox 360's we don't have them in stock in our Microsoft store anymore.

I apologize for the inconvenience and I hope this helps.

Hello RYUUJI SORA,

It seems there is no way of buying a new official Xbox One Power Supply.

Maybe this can be of some help : https://www.reddit.com/r/xboxone/comments/9rcr76/tips_on_getting_a_replacement_power_supply_for/
