How to use

Install the PSU in a compatible ATX chassis following the motherboard and case manufacturer instructions. Connect the 20+4 pin ATX cable to the motherboard and use modular cables for CPU, GPU and storage devices as required. Ensure the AC mains voltage matches the unit’s input range (100–240 V) and secure all connectors. Allow space for airflow around the 135 mm fan and route cables to maintain good case ventilation.

Recommendations

For reliable operation, keep the power supply and system environment free of dust, use a properly rated surge protector or UPS if mains quality is unstable, and ensure the case provides adequate airflow to maintain cooling efficiency.
