Computer just shutting off every 10 - 30 minutes when playing a graphically intensive game. Help?

[Scariest Fish]

So I have run into quite the frustrating issue. Yesterday evening while playing a rousing game of Final Fantasy XIV my computer shut down. All at once no delay no notice nothing just everything went black and then it immediately went into starting up. This has happened pretty consistently about 7 or 8 times.

At first I thought it was the GPU overheating but after installing HWMonitor my gpu never goes above 66C. I moved the gpu over to a new PCI-E slot and that seemed to work for about an hour at which point it once again turned off without any warning. I am absolutely baffled and frustrated as to what could be happening here. I built this about a month and a half ago after saving up for it for quite some time. I have listed the build below. Any answer besides "your build, along with all your very hopes and dreams, are dead" would be very helpful and welcome.

UPDATE: After, leaving the computer on for two hours while I was at work it didnt die again. I think it has to do with the load put on it by this game.

Again, any help would be massively appreciated. Thank you.

If the pci thing worked it might be a motehrboard issue. It could be a power supply issue as it only happens when the system is under high pressure. Also check if the overclock is stable on your cpu and if the cpu itself is being properly cooled
