Your system requires around 400w on full load. I would go with a 550w. If you plan on adding another video card later I would get a 700w.

If I were indeed decide to put a 2nd video card in, is 700w the minimum you would suggest?

with 2 gpus you will need ~ 550w- 600w for full load. So 700w minimum.
