fully overclocked system gtx 780 sli psu?

[coinmaster]

So I ordered a 850 watt platinum psu for my new build which will be a 4770k, 780s in dual sli, 2 ssds, an h100i, about 6 fans, and a sound card and a few hdds in the future. I will overclock everything as high as it will go.
I just saw on newegg that the same model psu was going for the same price at 1000w and now I'm wondering if I should return my 850w.
Am I missing out?

only if you want to, see if they would make an exchange and extra power for additional hd's or newer upgrades down the road never hurts.
