Both show ~300w for a single card. I can imagine that running SLI will hit the 600w mark, add the CPU and you will push your Seasonic past its limit.
Both those values are total system. with the cards in SLI I'd assume they'd pull about 200-250 each.
CPU and components would pull 100-150, meaning im within the power threashold of the PSU.
I will be upgrading, but im not 100% convinced that power is the problem.
SKY uses the following for reviews:
Intel i7 3930K @ 4.5GHz
Corsair Vengeance 32GB @ 1866MHz
ASUS P9X79 WS
2x Corsair Performance Pro 256GB
Samsung 305T / 3x Acer 235Hz
Windows 7 Ultimate N x64 SP1
The 3930 @4.5, ram and mobo will pull a hell of a lot more from the PSU than my 2500K, 8gb @1.65v and mobo...
so for one card, I'd estimate the draw with one card to be around 260w, add another card, I'd assume 450-500 tops, then add in my pump, and fans... which are pretty much nothing, and boom... within the envelope.
Toms review of two 660tis shows draw as the following:
