Which one should I choose?

[Mrkimmy]

Hello everyone! I need help choosing a 850W Power Supply. Do you think 850W is a bit too much for my build: http://au.pcpartpicker.com/user/Mrkimmy/saved/DGCCmG

EVGA SuperNOVA 850W G2 Gold Power Supply 

                                   or 

Corsair AX860i Platinum Power Supply

 

or should I just get the 750/760W? If I get a Dual-SLI in the future, do you think 750W power supply would be enough?

You could go as low as 550w, anything under might be pushing it

EVGA Supernova G2 750W if you are planning on GTX 970 SLI.
