Question gets asked a lot .... so making this so I can just link to it:
Power Supply Requirements (As Per nVidia):
n = Number of extra cards (so for for 2-way SLI that's one extra card, 3-way 2 extra cards, etc)
980

980 Thermal and Power Specs:
98 C = Maximum GPU Tempurature (in C)
165 W = Graphics Card Power (W)
500 W = Minimum System Power Requirement (W)
2x 6-pins = Supplementary Power Connector
SLI - 500 + n x (165 +20 peaks) = 685 watts for 2 cards

970 Thermal and Power Specs:
98 C = Maximum GPU Tempurature (in C)
145 W = Graphics Card Power (W)
500 W = Minimum System Power Requirement (W)
2x 6-pins = Supplementary Power Connector
SLI - 500 + n x (145 +20 peaks) = 665 watts for 2 cards

780 Ti Thermal and Power Specs:
95 C = Maximum GPU Tempurature (in C)
250 W = Graphics Card Power (W)
600 W = Minimum System Power Requirement (W)
One 8-pin and one 6-pin = Supplementary Power Connector
SLI - 600 + n x (250) = 850 watts for 2 cards

Titan Z Thermal and Power Specs:
95 C = Maximum GPU Tempurature (in C)
375 W = Graphics Card Power (W)
700W (with a minimum 12V current rating of 42A on a single rail) = Minimum System Power Requirement (W)
Two 8-pin = Supplementary Power Connectors
SLI - 700 + n x (375) = 1075 watts for 2 cards
