A key feature of the CORE GX ATX3 series is the inclusion of native 12V-2×6 connectors and modular cables capable of handling over 200% instantaneous peak power consumption. This makes them well-suited for systems with high transient power demands, such as those equipped with the latest high-end graphics cards. To enhance thermal performance and reliability, Seasonic has implemented its OptiSink high-efficiency heat dissipation technology, previously utilized in their higher-end FOCUS V4 GX models. This technology significantly reduces circuit volume by 48%, allowing for better airflow, and increases thermal conductivity by eight times, improving heat transfer away from critical components.
Cooling is further optimized with a 120mm HDB (Hydraulic Dynamic Bearing) fan that supports S2FC (Smart and Silent Fan Control) intelligent temperature control. This ensures the fan operates quietly under low-load conditions while ramping up appropriately when higher cooling performance is required. The CORE GX ATX3 series comes with a 7-year warranty, reflecting Seasonic's confidence in the durability of their products. Additionally, the power supplies include embossed modular cables for cleaner builds and easier cable management. Pricing is set at approximately $68 for the 650W black model and $82 for the white version; $96 for the 750W black model and $110 for the white; and $123 for the 850W black model and $137 for the white variant.
