Will 750w be enough for 980 sli?

[True Buie]

Heyo people

I'm soon going to buy some refurbished 980's for a nice price, and I was wondering if my EVGA Supernova 750w G2 would be enough to supply them. I've seen threads around saying it should be enough, as long as the PSU is off sufficient quaility, which I would mean mine is. Currently I have my i5 overclocked, but if needed I can downclock it once again. I'll list rest of the system.

Computer specs:
i5 4690k @ 4.9Ghz 1.385v
Noctua NH-D14
Gigabyte z97x-Gaming 3
Corsair Venegance Pro 16gb (2x8)
Current GPU: GTX 960
EVGA Supernova 750w G2
Samsung 850 evo 250gb
Western Digital 2tb

Cheers

Nv recommends 600w for a single card, and lists them as 250w.
While it's unlikely to use the full 850w, you'd certainly be pushing your psu very hard and there's a good chance you'd run into problems crashing, maybe even damaging something eventually.

Thanks for replying

I don't quite know if it's trustworthy or not, but could shed a little light on it, whether it's nonense or not.
