Hi, my build is a amd fx-8320 with a nvidia gtx 780 gpu. I'm also over clocking this processor to 4.0 ghz, I currently own a Cooler Master 750 watt power supply, I just want to know is this enough watts? Any answers are very much appreciated, thank you!
If motherboard is taken into account I own a sabertooth r2.0 990fx.
