Stick with Antec or Corsair. Some actual manufacturers apparently make only high quality. Those include Zippy-Emacs, Enermax, Win-tact, Enhance, and probably Etasis and Delta.
A PSU's quality can't be judged by its brand name. For example, Corsair's VS and CX series. Even their GS series is below Corsair's previously high standards. It's as if Corsair only cares about maximizing their profits these days.
Antec has a few PSUs to be avoided too, so that's why I never recommend PSU brand names. Instead, I only recommend individual units while ignoring brand names. I wish everyone else would too.
