well, i built my OSX + 4790k hackintosh with a 450w corsair; since it only has a Nv 750 (no need for anything more since it won't be a games machine) it hardly uses half that.
but yeah, EVGA is pretty much the top dog these days.
still, if you want total silence, you should move the pc to another room. OR... you can buy a good aftermarket CPU cooler and replace the fans with silent models. the cpu fan will be making most of the noise, not the PSU.
