yeah the ocz modxstream pro500 is a good psu I would go with the 700 modextream for future upgrades. I have used the 700 and the 850 in few builds I did recently for some friends. I think I got the 700 for 69 from newegg.
You won't need over a 550w PSU for your needs. I would look at Corsair, SeaSonic or Antec in that range. You could go with a 450w but to give you a little more head room for OCing, the 550w meets your needs.
