S12III SERIES
The S12III Series is available in the standard ATX Form Factor and in wattages that are common for a PC system. The Seasonic S12III Series achieves the 80 PLUS® Bronze standard, 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 reduce energy waste, resulting in savings on energy costs for users. Additionally, the S12III units utilize the LLC resonant converter design and the industry’s leading Smart and Silent Fan Control (S2FC) for optimal performance and quiet operation.
