It´s a bad or failing NCP4205 chip,while the fan speeds up,the HDD runs and overloads the chip,Use an infrared camera and remove the power supply but don´t disconnect it,now locate the NCP4205 chip located where the very back of the fan is,then try playing the game,or have someone press the A button as if they were going to play "while they are doing that ¨pay attention to the chip getting hot through your infrared camera,if so then replace it,but if it´s not that then you have another issue,"note this is only when you start to play a game,you could of had the system on all day,But as soon as you try to play a game,either a disc or downloaded from the xbox game lobby it´s the same condition,it turns the whole system off and you´re only left with a control flashing,,Hope this helps everyone.

I have the same issue, but I replaced my fan with a new oem fan and replaced the power brick with a new oem power brick. Still shuts off under load but idling at home screen it doesn’t.

Did you resolve your problem in the end? I have the relative same problem. Console and brick just cut out mid game. 5 minutes top. Then I have to mess about trying to get the bricks light back on!

I've had the very same issue with my xbox, I also thought it was the power supply and I changed the psu and it still bombed out under games load. I then rigged up my xbox to a 600w pc psu that pushes 25a on the 12v rail and still it crashed under game load, after alot of stripping down and testing i quickly learnt the issue was indeed the thermal paste on the chip. The OG thermal pastes application was so poor, it was caked all around the outside and minimal paste on the chip itself, after cleaning it all up and rethermal pasting.... it's working 100% and I'm still using the 600w pc psu as my main power supply the OG Xbox power brick is junk.

I'm in a similar boat but with my Xbox One X, it shuts down after i load a game up, once i start the match in lobby it will shut down but i can watch videos on youtube all day. I replaced the thermal grease and power cable and had the power supply and everything else tested with no results or answers. I also removed all dust. i have been hearing and reading it could be a Hardware/Software issue on Microsoft end. I can't play any games. Also were any of you on YouTube before they noticed this issue.
