Can i sli two of either gtx 660 or 660 ti with the ocz modxtream pro 700w power supply?
Playing Skyrim on on a single 660Ti in an I7-3820 system, with a ~90% efficient power supply

246w x .9 =~222w load
222 + 150* ( TDP ) = 372w ( * When running SLI, the secondary card doesn't draw as much power as the primary so that figure is high )
Not all of that power would be drawn off the 12v, modern systems still use 3.3v and 5v power ( figure around 40w or more for a dual card system, depending on peripherals ) The MXSP doesn't use DC to DC conversion
Also, it won't all come from 1 rail, graphics cards get some of thier power from the pcie slot ( The cpu
and motherboard connectors of the MXSP are on 1 of the 2 rails )
Some games will draw less, some a bit more, can't see any problem using either card in SLI
