Your psu is just fine. HD 7770 can run on 350 watts psu. If you are worried about your psu try to get a quality psu brand like seasonic, corsair or antec. Don't get me wrong here.. your psu is okay unless you add more stuff on your pc or oc.

You're good. Your whole system draws less than 200w at full load.

If you have crashing or sudden shutdowns, then you should suspect your PSU first; however I agree with those above, it's probably fine and I wouldn't worry unless you have problems.

If you do have problems, here is a handy reference for finding quality power supplies: http://www.eggxpert.com/forums/thread/323050.aspx
