Your Xbox One console may unexpectedly turn off under the following circumstances:
The console is too hot.
There's a problem with the power supply.
Reset your internal power supply
The Xbox One S and Xbox One X have an internal power supply that works in all regions worldwide. If your console won't turn on, it may simply need a power reset. Often, power issues are due to the power supply resetting after a power surge.
To reset the internal power supply, follow these steps:
Unplug the power cord from the console.
Wait 10 seconds.
Plug the cord back into the console, and then press the Xbox button on the front of the console.
or perhaps your power supply is clogged and overheating...

I had this same issue I saw a few post about doing the hair dryer trick but i didnt want to take mine apart. I just used my vacuum using the tube tool and made circles from the outside on the shell where the fan is for like 10 secs. Then it turned on with no issues

Also open your system up and clean the inside look for any foreign objects around the power button area ,I did this and my system works fine now.
