How to use

Install the PSU into a compatible ATX 3.1 chassis, securing it with the supplied screws and connecting the main 24-pin motherboard cable, CPU power connector, and required PCIe power leads to the graphics subsystem. Use only the necessary modular cables to minimize clutter and ensure proper airflow. Verify that fan headers and system grounding are intact before powering on. During first boot, check system voltages in BIOS or monitoring software to confirm stable operation.

Usage recommendations

For reliable long-term performance, operate the unit within recommended ambient temperature ranges and provide adequate case airflow. Replace or reseat modular cables if connectors show signs of wear, and ensure compatibility of PCIe power connectors with your graphics cards' requirements. When planning multi-GPU or heavily overclocked configurations, allow headroom above peak estimated system power draw to maintain efficient operation.
