750 or 850w PSU

[amulsingh01]

I found the EVGA P2 power supplies that I want on sale on amazon and I was wondering if I should get the 750w or the 850w.

I will most likely have the new I7-7700k and a GTX 1070.

Here is the rest of the build- https://pcpartpicker.com/list/F2RrRG
Thank you in advance.

even a 500W PSU is ample power for that card. have you considered the EVGA 550G2? it is a fantastic PSU, and platinum efficiency is not really a need as gold is already great.

even for sli a 650w would be enough lol

If you really want the P2 I would get the 650watt version since they dont make a 550, as others have said 650watts is overkill for your system you certainly dont need 750. The G2 550watt would be fine, I also really like the corsair RMx550.
