How to use

Install the CORE GC-850 into a compatible ATX case following standard PSU mounting orientation and grounding practices. Connect the 24-pin ATX motherboard cable and required CPU, PCIe, SATA and peripheral cables using the fully modular connectors included. Ensure the AC input range (100–240 V, 50/60 Hz) matches your mains supply and secure the AC cable. Monitor airflow and cable routing to maintain adequate ventilation inside the case.

Recommendations

For reliable operation, allow at least one case fan for intake or exhaust in addition to the PSU fan, keep cables tidy to avoid obstructing airflow, and verify GPU power connector type before installation. Use the unit within its specified input range and load capacity, and follow the 7-year warranty service procedures provided by Seasonic for support.
