I had to replace mine a month ago and it would take too long and just bought one off ebay, the piece of shit fan never stops working even when the consile is on standby.
I will have to "replace" the original one with MS now 😒
Yea, buying third party bricks that don't have Microsoft approval is not really advisable. I mean, this is a power supply, if one component is done on the cheap, it could fry your whole console. Worst case scenario, the whole thing could be a fire hazard.
Some may work, but I personally would never get one that isn't at least licensed by Microsoft.
