Ensure the PSU is connected to a grounded AC outlet within the specified voltage and frequency ranges. After connections are secured, power on the system and verify stable operation and correct voltages in BIOS or using monitoring software.
Usage recommendations
Verify that your total system power draw stays within safe limits of the 650 W capacity, leaving headroom for peak loads. Keep internal airflow unobstructed around the 120 mm fan and periodically remove dust to maintain cooling efficiency. Use a surge protector or UPS for additional mains protection.
