Okay, so I bought an 8 pin power connector a little while ago and just now decided to use it. My motherboard (ASRock A320M) has a power connector slot for an 8 pin power connector. But when I plugged it in and started playing Paladins, within literally 10 minutes, my entire computer shut down. When I was only using a 4 pin in the 8 pin slot, I never had this problem. Could it be just the cord itself? Why did this happen?
