SLI 780ti on existing 850W power supply

Thoughts on whether I can drive a 780ti SLI configuration with a Cooler Master 850W or am I going to need to go get a 1050W or even a 1200 watt?

Seems okay, but close, to me. I thought I'd get others' opinions just in case.

The rest of the things in my system that draw power are:

i7 2600k (not overclocked)
Water cooling
2 SSDs
Optical drive

The build is for gaming (mostly Battlefield 4)

  1. What Exact Coolermaster , if it's the V series it will work.
  2. Not the V series, unfortunately. I went ahead and bought an AX1200, which should do the job.

    I like it. Plenty of outputs to spare in case I need them.
