Currently I have a CS650M. I want to upgrade to another fully modular PSU but I also want to watercool my PC and I don't know how many watts I need total. Any and all answers are appreciated.

Specs:
i5 6600K @4.6GHz (Will be watercooled)
Gigabyte G1 Gaming GTX 1070 (Will be watercooled)
Kingston SSDNow 240GB (No watercooling)
WD 1.0TB (No Watercooling)
Gigabyte GA-Z170X-Ultra Gaming
5 fans (For watercool loop)
2 240mm radiators (For watercool loop)
EK-XTOP Revo D5 PWM - Plexi Pump (For watercool loop)

How many watts will I need for this setup? Also, if you can, please recommend a fully modular PSU for a setup like this.
