original psu is g7 power extreme 880w
latest psu is cit 600w

When i go to play any games the computer will suddenly shut down and restart or it will black screen and when i restart , it hangs on the bios.....i changed out psu because i thought it was that causing the problem but the newer psu is still causing same issues ...do i need a modular psu with the msi 780 ti , i have done mem test , hard drive tests , reinstalled windows (windows 10) still having issues.... been happening now bout 3 weeks , the entire machine has been taken apart and refitted ......its prob a simple issue but it would good to get help on the issue ...if u need more information i can give u that ...not sure if this is enough
