SilverStone recently introduced three new power supplies in the Element Series, which are designed for high efficiency operation. The new models include one 400W and two 500W units that are particularly well suited for use in SFF and HTPC cases. We will be taking a detailed look at the ST50EF-Plus, which has been tested and approved by the 80 Plus program to deliver greater than 80% efficiency across all loading conditions (from 20% to 100%). As a result of greater efficiency, the power supply generates less waste heat. This allows the 120mm cooling fan to operate at minimal speeds, ensuring near silent operation for most applications.
