Sounds about right, I pulled 1140w (from wall) during the CM load em up PSU contest with 580 LE SLI & 5Ghz 2600k.
Extremely high OC's with extremely strenuous F@H work units. Typical usage won't have you near that.

You mean they advised you not to get a ridiculously overkill PSU? Sounds like good advice, but doesn't really apply to the people getting the most power hungry modern GPU's and 2 or more of them. Especially when one think's they may in time drop in even more.
However, fact is a good 750w will run any SLI/CF setup. In some circumstances will they be drawing over their rated? sure, but most won't even hit OPP untill ~820w (largely depends on unit) and even then are still running safely, within specs, at silver or gold efficiency. The circumstances to do that are generally unrealistic unless boincing or folding at the highest OC's you can obtain.
Admittedly I got the FSP AU-1000PRO because I would routinely pull over or around 830w from my old 750w PSU, looking back.. I should have kept it (as I sold the 580's for single 690)
The newer series are drawing less juice, and that trend will in all likelihood continue.
