PSU for gtx 980ti sli setup

[Drago1147]

Will be adding a second gpu to my system. Not enough time to properly research what psu I should buy, so I will follow advice blindly.

Please share your wisdom.

My specs:

CPU: Intel Core i7 5820K 6x 3.30GHz -oc-ed to 4.4
CPU water cooling: Cooler Master Nepton 240M
Board: MSI X99A Gaming 7
GPU:Asus GeForce GTX 980 Ti Strix OC Aktiv PCIe 3.0 x16
GPU:Asus GeForce GTX 980 Ti Strix OC Aktiv PCIe 3.0 x16 <- I'm adding this one
2 ssd's
Current PSU: EVGA SuperNOVA 750 G2 750W ATX <- makes crackling noise under load. probably garbage quality.

I am currently looking at this PSU: CORSAIR HX1000I. 1000w.

If I am not mistaken the two gpu's consume tops 375w. That will leave 250 for the rest of the system. Would that be enough?

You want a decent 850W for the SLI , The HXi 1000w is a great one , that would be more than enough.

The G2 you have is actually top Quality made by Super Flower.

Your cards are highly overclocked versions that use more than normal GTX980ti power. 2 8 pin connectors each.
That is not likely to be satisfied even by a good 750w psu.
The 1000w unit you are looking at should suffice.
