Cuchulainn is on a distinguished road

A Radeon HD 5770 needs not more than 108 W of power, your CPU has at normal clock settings a TDP of 95 W; a Radeon HD 5750 needs about 20 W less. If energy efficiency and cost matters, it's better to use not a overdimensioned PSU. But a normal 300W PSU with your CPU+GPU is probably louder than most 500W PSU's would be.
