Good power supply replacement for my old xbox. Although I am planning on getting the newest one, I will try and see if this works with it as well as it says that it is compatible. But, it works great as a replacement for my old power supply which stopped functioning. It functions as it should with LED light indicators such ornage light for standy by and green light for power on mode. It is super quiet and does not make barely any sound when using and it is cooler than I thought that it would be when under load for a long time.
