It works except it uses more power when not on and is noisier than the standard Xbox 360 Slim power supply I was given , when I first bought it for my Xbox 360 A nice plus would be that the fan in the power supply seems to push the heat this unit produces at a good rate, although it is accompanied by noise. For now, I'm hoping it won't be covered in dust, which is why I bought it in the first place when my version of Microsoft started moaning at me. 4 stars for what I needed it for and 3-3.5 stars for the extra noise and 30 extra watts used in sleep mode.
