Will 860w PSU be enough? I know many don't require power. I just copy pasted it from somewhere else.

Hello Hobson

To be safe, I personally would go with at least a 1000w psu for that system and to feel a little more comfortable a 1200w psu.

Ok thnx, What is the max that could happen. Thing is that I already have a 860w PSU from my old system so gotta sell it before I build then 😞

Your 860w psu might run it but then again maybe not. With that kind of water cooling I know you're going to be overclocking too and you will more than likely run into stability issues when overclocking.

One gtx 780ti and no overclocking requires a 600w psu, this is for total system power draw. You have 2 of them which right there is going to need another approx. 200 watts. Add in your cpu at 140 watts and you're already needing a 940 watt psu and that's not counting everything else. if I were you I would be looking at a quality 1200w psu to run what you have comfortably along with overclocking.

The more headroom you give your psu , the cooler and quieter it will run and the longer it will last.

it will run it, but it will be on the fence so to say.
run things on stock and mabye a slight oc on CPU.
and the cooling you have there will be on the fence too.
for OC i would recommend 2x 120 fan slot of radiator per OC'd part.
so personaly if you going to cool those you need to get some thing to monitor the water and the temps on GPU's and CPU.
