Darthutos :
what is your budget for the power suply for the build? id est how much are you willing to spend on the power supply?
edit: right now it looks like a 600 watts unit is recommended, however, which brand and model is up to how much you are willing to spend? Please stick with seasonic and evga brands.
600W? for a 60W CPU and a 75W GPU?
this build will run on a 300W PSU
for practical reasons, I suggest a 450-520W unit -- they're the same price or cheaper than most lower watts quality units and provide upgradability to your system
I'd probably go for a XFX Core / Pro with 450W, a Corsair CXM450 (AKA CX450M / CX450 semimodular; grey letters on the unit), a Super Flower Golden Green HX 450W or any Seasonic unit with 450-520W (including other OEMs like the Antec HCG)
if money is a real issue and you cannot afford any of those under any circumstances, an EVGA B1 is kinda okay
but I suggest getting one of the units suggested above, if possible
