I think 500 Watt PSU will be quite enough.

You are going to use the Graphic Card in your system. So it is recommended that you must use a power supply minimum at around 550W. Regular computers normally has a 250w power supply. It is enough for the computer without gpu. But graphic cards need more power supply. Buy any 550w power supply.

If you are building a future-proof computer, its better to get a 650 or 750 Watts SMPS. More more because you can connect a lot of stuff and keep it connected will not hamper the computer's operation...
