you need a 430W minimum , so i add always 200W to be safe
so a 620W psu should be ok

I would go with either a very high quality 650W PSU or a mediocre quality 750W if you want some headroom.

Your rig is a power hog. I wouldn't go with less than a good 620 Watt.

You need about 550w due to the Crossfire of the 7850's
