The G12 GM series is available in the standard ATX form factor and in wattages commonly used for PC systems. The Seasonic G12 GM series achieves the 80 PLUS Gold standard with at least 87%, 90%, and 87% power consumption efficiency at 20%, 50%, and 100% load, respectively. This efficiency, combined with active power factor correction, allows the G12 GM series power supplies to reduce energy waste, resulting in savings on energy costs for users. The G12 GM units are not only highly efficient but also utilize LLC resonant converter design and industry-leading Smart and Silent Fan Control (S2FC).
