300 Watt is really nothing, so I would say get at least a 500 watt (80 Plus dual rails if possible) PSU. You have a decent mobo and cpu there don't use a cheap power supply and have it blow up on you under load.
Oh, and don't get a cheap one that I've seen many people do. Go with a Corsair or Thermaltake brand, They will last years and are not that expensive.
