Hi,

I am looking at this PSU for my (gaming) build and am planning to use a high end card of gtx 680 / HD 7870. and I guess the main question is if this PSU 750W can support a future SLI/Xfire of the same card (starting w/ single gfx). Would be uncool if I need a new PSU when a second card comes!
Note that I do not plan to OC much.

Or if there are better deals for a PSU shoot away!
Thank you! :D
 
Safest bet would be to shoot for an 850W at this point. It seems Nvidia and amd are shooting for lower-power solutions, but sometimes they release a generation of cards that requires more power than the last.

Also, if you plan to OC at all, you need to consider 100-150W additional. It costs a little more initially, but it will be worth it in the long run:

You'll be able to bring a power supply like this along from build to build for 5-10 years. Warranty is even 5 years compared to the OCZ you posted above which only has a 3-year warranty.
 


gtx 680 Sli runs fine on a 750w-

Here is Guru3D's power supply recommendation:

GeForce GTX 680 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 680 SLI - On your average system the cards require you to have a 750 Watt power supply unit as minimum.

If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina.What would happen if your PSU can't cope with the load:

bad 3D performance
crashing games
spontaneous reset or imminent shutdown of the PC
freezing during gameplay
PSU overload can cause it to break down
but good news is that their system is a power hungry x58(965 EE)system,if you have 1155 based system then i am sure 680 SLi will run fine on your system at stock speeds.

Thank you for the advice and links!
I decided to get the "CORSAIR Enthusiast Series TX750 V2 750W" from NewEgg which came up to ~$75+ after rebate. :p
Hope the fan sound is not loud like some of the reviews said!
