How to use

Install the PSU into a compatible ATX case following the case manufacturer’s instructions and standard safety precautions: disconnect mains power before installation, secure the unit with the included screws, and connect the 20+4 pin ATX cable to the motherboard. Attach SATA power cables to storage devices as needed, and connect any modular peripheral cables after routing them to minimize obstruction of airflow.
