Xbox power brick

Are you sure that it's your Xbox and not a broken power brick? If you have a friend with the same power brick, try his!

If your xbox works, you'll know that it's the power brick.

The reason your Power Brick is making a humming noise, is because inside of the power brick. Is a little fan, this fan keeps your Power Brick at the correct temperature. If your power brick gets hot, the fans RPM will increase and it will make a humming
sound because your XBOX Power Brick Fan is cooling down your Power Brick. Nothing to worry about unless it's a roaring sound.

do you have a friend with the same model xbox so you can try their power brick and also your power brick on their xbox? so try and see if its the power brick or console itself with the issue?

Cheers

You can try to reset the power brick by disconnecting it for 10 seconds and reconnecting it.

If you still have an amber light on the Xbox power brick, it means that the power brick has to be changed.

In this case, you will need to approach the Xbox support to request a change of the power brick.
