Could anyone tell me why my xbox one power supply stopped working then suddenly works 3 months later? I plugged it in and let the block sit over night then olugged it in to the console the next morning. It didnt turn on right away. It only turned on when i accidentally touched the power button.
Even though your power supply started working again, I do not recommend using it. Xbox has an article about its power supply, which you can find here. Do not use your power supply, order a new one instead. If you need any help please reply to this answer. Thanks, John
