A-Power is just a brand of cheap power supply made, so far as I know, by PowMax. Should be called MaxKaPow instead!
OK, lots of good power supplies about, Fortron Source, Sparkle Power, Aopen, Seasonic are all solid, followed by Antec's standard-grade, Enermax, followed by Codegen, JLE, and Foxconn. And that's only about half of the passable brands.
I'd probably go with the smallest-rating Fortron Source or Sparkle Power you think you can get by with (probably 300W) and get the model with 120mm fan. Be ready for huge prices, we're talking $25-30!
