Hey if someone could help me with this I would be very greatful.i am building a completely new pc for predominantly gaming and also video editing. So far I have come up with these parts:
I7 4770k
Gigabyte g1 sniper m5
Corsair vengeance 1600mhz 16gb
Corsair h100i
2x gtx 780
256 gb samsung 840
Corsair obsidian 350d

I was looking for a psu and the corsair hx 750 caught my eye. Would this be enough to power the system or should I step and get a hx 850.
Btw I plan to overclock both the cpu and gpu quite far.
Thanks for your time.
 
Solution
For overclocking all three you should definitely go for the 850w, as overclocking uses more watts. It will also run quieter than the 750w as the fan won't be spinning as fast. :)
