Which PSU Has Enough Juice for Me?

[Christopher Gonzalez]

Hey Guys!

I'm building a PC very soon with these specs:

i7 4930k
ASUS Deluxe X79 Blah Blah Blah Mobo
16 GB 2133 MHz
3 HDD, 1 SSD, more on the way
GTX 780 Ti (6GB if it comes out) I want room for SLI (Might go with 2x EVGA GTX 770 Classified)
And any ol' Optical Drive

I'm looking at the Corsair RM series of PSUs, which leaves either 850W or 1000W. I like the RM series because of their quiet-ness. How much wattage do I need for the above with 2x GTX 780 Ti's and room for a little expansion, just more drives and stuff?

Thanks!

1000w is plenty but look at EVGAs power supplies better quality and warranty
