G12 GM
The G12 GM Series is available in the standard ATX Form Factor and in wattages that are most common for a PC system. The Seasonic G12 GM-Series achieves 80 PLUS® Gold standard, providing at least 87%, 90%, and 87% power usage efficiency at 20%, 50%, and 100% operating loads, respectively.
This efficiency, combined with Active Power Factor Correction, enables the G12 GM series power supplies to reduce energy waste, resulting in savings on energy costs for users.
Additionally, the G12 GM units utilize the LLC resonant converter design and the industry’s leading Smart and Silent Fan Control (S2FC) for optimal performance and quiet operation.
