Introduction

Today, Sea Sonic Electronics introduces a new range to our product lineup, the S12II series, designed for Energy Savings to meet the 80 PLUS® specifications.

The S12II series is made up of 330, 380, 430 & 500 watts units, we will be reviewing the 500 watt model.  Each of the Windows Vista™ ready power supply not only meets but also surpasses the stringent 80 PLUS® requirements.  This feature combined with a power factor correction factor of 0.99, total computer system energy usage can be reduced by up to 20%, surpassing even the original S12’s performance levels.

Technically, the S12II is a dual 12V rails Double Forward Converter circuit design.  High grade Conductive Solid Polymer Aluminum Capacitors are used to further enhance performance and reliability.  These capacitors offer improved heat resistance and conductivity over the market standard electrolytic capacitors.
