Will 1000 Watts be sufficient for 2X GTX980 + 4 SSD's

I recently bought a EVGA 1000 Watt (platinum) PSU to run my four 840 Pro SSD's (2 each in raid 0) and a 1TB HDD. I'm waiting for the new GTX980 to come out very soon - plan to buy just one initially and maybe SLI another one later on (only if I need it). If games don't run on ultra everything, I'm not happy. In the mail (literally) is my new Asus X99 mobo (Rampage V) + i7-5930K CPU + 32GB DDR4 2666Mhz (all to be just moderately OC'd). Monitor res = just one 2560X1440 @120Hz re: the GPU load. Now I think I may have messed up and maybe got a 1200 Watt PSU instead. But all that new tech does actually use less power compared to previous generation. So am I good to go or should I list my PSU on eBay and then get more power? Informed comments welcome.

Don't trust those calculators; One of them might say you need 1200W and one might say you need 800W.

Considering that a 1000W PSU is able to run the R9 290X in 2-way CrossFire pretty easily, I find it hard to imagine that a similar PSU wouldn't be able to run the GTX 980 in 2-way SLI, considering that the new Nvidia cards are supposed to consume less power than the current ones.

I initially thought I was good to go too until I plugged my configuration into in the the ASUS recommended power supply estimator tool (http://support.asus.com/powersupply.aspx) - it came up 'minimum recommended PSU should be 1200 Watts!

Good point. I expect you're right. Thanks.
