    Would a Corsair AX860i be sufficent to run a system based off a ASUS Rampage V Extreme, with Intel i7 5930K, 64GB Dominator Platinum DDR4, and 2x Asus Strix GTX980 DirectCU OC, in SLI, with 3 water cooling pumps, 2 850Pro 1tb SSDs, Corsair commander mini, and a lot of fans (~10 fans)?

    Or should I aim for the AX1200i/AX1500i? Since PSUs perform optimally at about ~50% load, I want to have full stress load somewhere near the 60-70% mark so the system keeps pace at around 50% load at most of time.

    I will propably not OC the setup, but if theres temperature marginal, Ill overclock it a tiny amount (both GPU's and CPU's if theres marginal).

    I guess the 980's will eat most Power of the system.

    Using a power supply calculator, your wattage comes out to roughly 650 watts. That's calculated using standard GTX980s, so 650+ for overclocked cards and overclocked CPU. Easily looking at 700 all together. 12v amperage you're looking at 47.2A, which is well within the AX860's 71A rating but you're close to the AX860's max wattage.

    With that said I'd suggest the AX1200. It will be less stressed and therefore live an easier and longer life.

    I got a 583 W for stock. I think it does worth, like Cartman372 said, to buy a higher wattage psu.

    Yep, you'd peak at 80-100%. Guru Hilbert himself reviewed AX860i and ran it with two GTX 590, pulling 730W from the wall. Knowing that peak consumption of single 980 is 275W, I'd say it's a fair comparison. Except you have about 100W worth of water and cooling gear.

    Based on 760i review I've read AX series are built to withstand great continuous overload but nevertheless AX1200i would be more adequate. Too bad they don't have 1060i model :)

    I think you'll be fine... no need to upgrade, you might be better off with a higher wattage psu though in the long run, but i'd stick with the same psu.
