Rosewill SilentNight 500 W @ techPowerUp
 

Rosewill just introduced their first passive cooling PSU: the SilentNight 500 W made by Super Flower. It offers Platinum efficiency, high performance, and noise output at close to zero levels because of the absence of a cooling fan. This unit goes up against some strong competition, but has many interesting features.
