These quality power supplies are backed up by Sea Sonic’s 7-year worldwide manufacturer’s warranty. New Seasonic OptiSink DesignThe overall quality and reliability of the new CORE GX ATX 3.1 Series has been greatly improved by a brand-new PCB (Printed Circuit Board) layout and the implementation of automated surface mount technology during production. which minimizes human production errors.By using a redesigned PCB combined with smaller MOSFET and heat sink components. the internal space within the power supply was increased to enhance heat dissipation and airflow to result in better component cooling.The eightfold increase in heat dissipation keeps the internals of the power supply cooler. eventually leading to improved product quality. long-term reliability. and more efficient operation.The redesigned layout of the power supply components and its improved thermal performance creates versatility and allows the power supply to be safely installed in any orientation.The OptiSink design is an eco-friendly solution that not only lowers the costs of material usage and production but also leads to energy savings in the long run.Next-Gen and Legacy GPU CableIncludes native 12V-2x6 and 2× 8-pin adapter for maximum compatibilityS2FC - Smart And Silent Fan ControlThe 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.
