How to use

Install the SFX-300W into a compatible SFX or SFX-to-ATX adapter bay following the case manufacturer’s mounting instructions. Connect the 20+4 pin ATX cable to the motherboard and attach the SATA/Molex or PCIe 6+2 pin connectors to your drives and graphics card as required. Ensure the AC mains cable is rated for your local voltage and plug it into a grounded outlet. Power on the system and monitor voltages and temperatures during the first boot.

Usage recommendations

For reliable operation, avoid running the supply continuously near its maximum rated power. Ensure adequate case airflow around the 80 mm fan and use a compatible cable configuration for your components. If you plan to use a high-power graphics card, verify the combined system power draw to remain within the 300 W rating.
