The function and processing of the power supply are quite good. The supplied power cord is a bit short, but okay. The only drawback is the volume of the built-in fan, is reminiscent of X Box 360 days Lunch (each of one of the first X boxes has knows what I mean), the part is louder than the console itself. There is no comparison to the original power pack from Microsoft.
Conclusion: In order to bridge the time until the original replacement power supply is back, absolutely ok. Not suitable for continuous use imo, the fan volume annoying. Hence only 4 stars from me.
