For a single 7850, the 520W Seasonic (or any other 500W) PSU should be more than adequate..

Additionally, u could use one of the many PSU calculators available online to estimate the 'wattage' u would require. Here are a few links:
eXtreme calc
thermaltake calc
Cooler Master calc Asus calc
MSi calc
"be quiet!" calc
Corsair calc
