Why does my Xbox one make a sound but doesn’t power up

Hello Iphone! I'm Kris and I'd be happy to help you with your question.

Sorry to hear you have this issue. Does it light up at all? Have you tried a full power cycle?

Why did you pay for an Xbox One with out a power source? How much does one pay for a non working console? The whole thing sounds fishy to me.

Translated-

Is it normal for my Xbox One Power Supply to be making noises? The one from my 360 makes no sound.

The fan theory does make sense. But this does not sound like a noise a fan would make. It's more of a electrical buzz or whine if that makes any sense. Kind of like a old computer would sound when it was writing stuff on to the hard drive but just a bit
more intense and high pitched.

I was reading up on some forums and it seems that a lot of people have had this same issue specifically with kinect less versions of xbox one. It's supposedly the gpu making the noise when it's at a low power state and it seems many Xbox ones are affected.

My xbox one makes sound but it won't turn on after a power outage
