is the 750 power supply 80PLUS certified? if it then the 750 will do great but it is not then I would only attach the 780 to the psu (power supply unit). 950 would only be needed if want three way SLI (meaning three graphics cards connect to each other through a SLI bridge). When it comes to SLI you need to have two tree or four identical cards (in 660TI case you can add a maximum of two additional 660TI - so three in total) so you will need to see what the SLI configuration the certain cards supports.
