Connect the 20+4 pin ATX cable to the motherboard main power socket and attach the SATA connectors to storage drives as needed. Ensure the case fan orientation and cable routing do not obstruct airflow. Connect the mains cable to a properly grounded outlet and switch on the system. Verify stable boot and monitor fan operation and voltages in the BIOS or with system utilities during initial power-up.
Usage recommendations
Use this power supply in systems where total system power draw stays well below 350 W to maintain efficiency and longevity. Keep internal case airflow unobstructed around the 120 mm fan and perform periodic dust cleaning. For systems with high-power graphics cards or multiple power-hungry components, select a higher-capacity PSU with appropriate connectors.
