Id say NO. Your PSU is NOT good enough for two video cards.
You need 600w or more.
If you want I can look some links to couple good psu that can do the job.

This was cheap and good enough. http://pcpartpicker.com/part/xfx-power-supply-p1750xxxb...

Id look even better ones like corsair new rm or seasonic "g" or "X"
Or Rosewill capstone 750 or lightning 800w.
