Get around a 600/650W good quality P/S to give yourself alittle overhead. Something from PC Power & Cooling/ Corsair/ OCZ/ Silverstone.
 
The Corsair 450 Watt unit would run it, the 520HX unit would do it with headroom, a 620HX would run it with a lot of head room, and then some.
 
Do I need a HEATSINK for the CPU? And if so,
what is the name of the item - I don't know anything
about heatsinks/fans.
