S12III SERIES The S12III Bronze Series is available in the standard ATX Form Factor and in wattages that are most common for a PC system. The Seasonic S12III-Series achieves 80 PLUS® Bronze standard of providing at least 82 , 85 and 82 power usage efficiency at 20 , 50 and 100 operating loads, respectively. This efficiency, combined with Active Power Factor Correction, enables the S12III Bronze series power supplies to lessen energy waste, which translates into savings on the costs of energy costs for its users. In addition to being greatly efficient, the S12III units utilize the LLC resonant converter design, and the industry’s leading Smart and Silent Fan Control (S2FC). 80 PLUS®BRONZE The 80 PLUS® Bronze certification indicates that a high percentage of the electricity is converted into useful power, therefore there is less heat lost and more money saved on the electricity bill. The 80 PLUS® Bronze certification guarantees greater than 82 , 85 and 82 efficiency at 20 , 50 and 100 operating loads, respectively. Sea Sonic’s Bronze Series is an economical choice with great performance and high built-in value. S2FC - SMART AND SILENT FAN CONTROL The intelligent thermal circuit feature is designed to find the optimal balance between the necessity to cool the components and the need to run the power supply in the most silent manner possible.
