Crossfire power needs.

[daren901]

Hi, I'm looking to crossfire my existing Sapphire Rx 480 +nitro 8GB with another.
My current set up is
i7 7700k with Arctic Freezer
MSI 270 A-Pro
2x16GB Ripjaws V
Intel M.2 512GB SSD
3 other hdds
EVGA 850w Supernova G2 Gold +

My question is will I be able to get away with using my current PSU, or do I need to start looking for something a bit more powerful?

The PSU is more than enough. Even the 750W could handle that and OC'ing w/o problems.

Thank you @clutchc
That's a great deal more information than what I could find browsing this morning.

This chart is handy for rough estimating the size PSU (good quality, of course) needed for different gfx cards. It includes SLI and Xfire combos too.
