So I am getting a new PC soon, and what I am going for is a build that will last me the next 7-8 years (hopefully). Although I am not water cooling when I get this PC, I probably will later down the line and I want to be prepared for that when I do, i.e I don't want to buy anything but water cooling parts (no other upgrades). My build can be found here: http://au.pcpartpicker.com/p/3CpHn. (please note that the only thing subject to change is the PSU.) I was wondering if I would need a bigger power supply, according to PCPartPicker my estimated wattage for my system alone is 1000w. Because I am new to the world of full system water cooling I have no idea how much power I would need for a loop to cool my 3-way SLI and my CPU. I know the Corsair AX1500i is coming out soon so I don't mind waiting for that if I need to. I imagine that water cooling doesn't take that much wattage but I'd prefer not to have my PSU constantly at full load. Also because I really have no idea about water cooling parts, I need someone to help me put together a list of good parts or a kit to get when I do decide to take the plunge.
