850 watts will be more than enough; you can even get by with something in the range of 600 watts. Get a good brand - Corsair, Seasonic, Antec, XFX.

Look for sales and promos on Newegg. You might be able to pick up a larger capacity PSU for a lower price when they have promos going on.

850W is way overkill, a decent psu with 500W is more than enough, it will have more than 24 amps, for two 7850, a 600W psu will do.
Get a psu from those brands above mentioned, there're others too.

Actually a quality 450w (&21a on +12v rail) is enough to run a
system with one 7850. So, I say take DJ's suggestion & get
something in the 500-600w range. Gives you plenty of headroom.
