Hello so i got brought a new computer for Christmas and since having it have encountered an error with the system each time i play a game either 1 min or 10 mins into playing the system reboots itself. so i contacted the seller and they said it would be a faulty gpu which seemed strange to me. so i ran some of my own tests and removed the graphics card (Geforce GTX 1070 8gb 256bit GDDR5) from the motherboard and started up wow on the lowest graphics settings and after 3 minutes the system rebooted itself, i then tried again with overwatch on the lowest settings and it rebooted on the startup screen. so i came to the conclusion that it was not a faulty graphics card and its something else could anyone help me here is the build of the pc with the graphics card taken out of it.

what power supply would you suggest, i think this is the problem as it still reboots with the graphics card removed from the system, also all temperatures are below 45 degrees
