You could run those components on a 380W Antec Earthwatts PSU, assuming you were not planning to add a second graphics card.
Just for the headroom, I'd probably choose the 500W Earthwatts model. Whatever the size, choose a quality unit that has full range active PFC (no little voltage switch) and is 80+ certified for efficiency. Antec, Corsair, Seasonic, and Enermax are among the more readily available quality brands.
