How to use
Install the PSU into a compatible PC case following the case manufacturer’s mounting instructions and standard safety precautions: switch off and unplug the system before beginning, position the unit so the fan intake has adequate airflow, and secure it with the supplied screws. Connect the 20+4 pin ATX cable to the motherboard, then attach SATA and peripheral cables to storage drives and accessories as needed. Verify all connectors are fully seated before powering on. Ensure the input voltage selector (if present) matches local mains voltage or use the auto-sensing feature where applicable.
Usage recommendations
For reliable operation, maintain sufficient case airflow and avoid operating the PSU near heat sources. Use the CSK650 within its rated power envelope and allow occasional brief load increases but avoid continuous overload. Regularly inspect cables and connections for wear, and consult Antec support for warranty-covered repairs or replacements under the 3-year warranty.
