Is it absolutely 100% imperative to have a 1,000W power supply for the following PC build?

*Core i7 7700K
*16GB DDR4 RAM
*ASUS Maximus IX Hero motherboard
*Two-way SLI Nvidia GeForce GTX 1080 ASUS RoG/STRIX edition

I'm in the process of building this, one part at a time as soon as I can afford it, and I've been eyeing the Corsair AX 860 Platinum 860-watt power supply.

I read a lot of positive reviews about the unit.
