Corsair didn't pick a good manufacturer for the RM 750 or 850 from what others have said.

If you are going to run the GTX 780 SLI on stock speed with an intel build also on stock speed - you could squeeze by with a 750.

EVGA 750 B2 $55 after $25 rebate ( I own 2 of these) Remember to register for the warranty if you buy this.

EVGA 850 B2 $84 after $15 rebate made by SuperFlower. Remember to register for the warranty if you buy this.

The nVidia recommendation is 850W with 65A or better. The RM750 only puts out 62.5A on the 12V+ rail. You can power it with a higher grade PSU (see LukaBoki's post for reference) with specs below that recommended, but that may not leave you much headroom for overclocking either the CPU or the GPUs.
