FWIW...
I've typically used generic (whatever came with the cheap cases) or Powmax brand (dual fan and high output for the price) power supplies, but recently I started using Antec. Got a TruePower 330 for my GF's computer and picked up a TruePower 430 (in an Antec 1080 case). Those things are SOOOOoooo quiet compared to what I've used, and the power output is very steady and very close to spec (looking in the BIOS system monitor). I also like the extra fan leads that are variable voltage. They're not cheap (around $60 for the 330W and $85 for the 430W, Newegg pricing with shipping) but IMO they're worth the money.
