It is a good idea to allow for 250 Watts for a single GTX 1080 FE. I would be surprised if you would be able to run two of those cards with a single 750 Watt PSU.
There are other factors to consider also. What other peripherals is the computer supporting? How many hard drives? How many fans?
My gut instinct is that a single 750 Watt PSU is not enough for two GTX 1080 FE cards. For two of those cards, it is probably best to go with at least a 1000 Watt PSU.
Also, most wall circuits (15 amps) top out at a capacity of 1800 Watts. Make sure you plug in to a wall circuit that can handle the load that you are putting on it. Popped circuit breakers and electrical fires are no fun.
