Built-in protection circuits ensure safe operation under common fault conditions.

How to use

Install the EON Series PSU into a compatible ATX case following the case and motherboard manuals. Secure the unit with the provided screws, connect the main 24-pin and CPU 4/8-pin power connectors, and attach peripheral and GPU connectors as required. Ensure proper airflow around the unit and verify cable routing to avoid obstruction of fans and components.
