How to use

Install the power supply into an ATX-compatible case following the case manufacturer’s mounting points and secure it with the provided screws. Connect the 24-pin motherboard main connector, CPU power connector(s), and required PCIe, SATA and peripheral connectors to the system components according to the motherboard and component manuals. Ensure correct cable routing to maintain airflow and prevent cable strain. Verify input voltage selector or auto-switching behavior if present, and connect to a grounded AC outlet using the supplied power cable. Power on the system and check for stable boot and voltage readings in BIOS or monitoring software.

Recommendations

For reliable operation, size the power supply to match peak system load plus headroom for future upgrades. Use quality power cables and a properly grounded outlet. Maintain case airflow and periodically clean the fan and ventilation areas to prevent dust buildup that can impair cooling efficiency.
