How to use

Install the power supply into a compatible ATX chassis following standard mounting procedures. Connect the main 24-pin motherboard cable, require CPU power connector(s), and the necessary PCIe 5.1 GPU cables directly from the modular ports to the graphics card. Use only the included modular cables to ensure proper fit and rated current. Verify that all connectors are fully seated and that the unit is secured before powering the system. Configure fan and power settings via the motherboard BIOS if needed.

Recommendations

Ensure system power requirements do not exceed the 750 W rating and account for peak GPU and CPU draws. Use the native PCIe 5.1 connectors for modern GPUs to maintain electrical and mechanical compatibility. Maintain clear airflow around the PSU intake and periodically check modular cable connections during upgrades.
