How much wattage for this system?

[T_A]

I'm planning on a new Skylake 6700k system with AIO water cooling
not sure what GPU yet, but i want enough wattage to be able to push 2 GTX980 equivalent cards (power usage wise)

I was thinking Seasonic X 850W which fits my budget pretty well, will it be enough?

Yes that PSU is a perfect fit as it will leave you with enough breathing headroom.

Ok so 850w it is then.

They dont sell evga PSU in my country, the RM850 (none i) costs 176$ vs 155$ for the Seassonic , is it worth the difference?
