Xbox One Power Supply question

I know this is for Windows 10, but I could not really find an answer anywhere else, so I figured I'd give it a shot :)

My Xbox one power supply had it's fan go out, so I bought a third party one (YCCSKY). So it's supposed to have two modes: standby and active. Or amber light and green light. When I first plugged it in, it stayed on the green light all the time, even when I power the Xbox off. Another time I plugged it in, it started with the Amber light, and then turned to green normally once I turned on the console, then once again, it would not turn back to Amber once I powered the Xbox off.

So my question is, is there some sort of setting I am missing that would make my power supply act right, or do I just have a crappy and defective power supply?

Thanks for your help.
