Easily. The 55nm gtx260 barely draws more than 100-120W each. Add in an OCed quad to the mix and you would still only be at ~450W.

easily...a 650w could do it.

The TX series is rated for actual 12v output.. so your 750 is more like other manufacturers 850 or 900W PSU's..

*I have the TX650 .. its rated for 818W absolute max ..with 52A single rail
Yours is rated for more...

Your tx650 is not rated for 818W absolute max, it is rated for 650W. Corsair just rates their units realistically. In a modern computer, 90+% of it's power is distributed over the 12V rail. Corsair rates their units with that in mind, 90+% of a PSUs capacity should be 12V. It's fairly standard for any PSU worth buying. Sure Corsair could stuff their max wattage rating by adding in more 3.3V/5V, but that wouldn't be very honest and people knowledgeable about this would call Corsair on it. If you push the tx750 to the limit it will do 900W: http://www.hardwaresecrets.com/article/505/8, but it still could only do 66A on the 12V which is what we see in ~800W units. Realistically, the tx750 is clearly a 750W unit.

yes, for sure. The only thing that may give it trouble is quad sli/fire.

As I said once already.. "compared to other manufacturers" ! Thanks for troll anyhow though. A little regurgitation for other readers that may have missed my point, may have understood your post.

*For the record, most cheap PSU manufacturers DO rate their PSU's for absolute max... so you had better start calling them on it!

We do call them on it, all the time. They don't care. Any reputable PSU company will rate their units just like Corsair. Most Antec, BFG, Silverstone, PC Power, Zalman, Xigmatek, Tagan, Enermax, Seasonic, Etasis and the better Cooler Master, Seventeam, FSP and Thermaltake units are rated just like the Corsairs. It is what you should expect from a decent unit, it's not something special just Corsair does.

Thanks for calling me a troll, it really adds to the discussion.

I think this guy knows what he's talking about. You guys are pretty optimistic about your power supplies.
