Installation & Maintenance Guide

Standard ATX PSU installation typically takes 15-30 minutes. Ensure system is powered off and unplugged before proceeding.

1. Remove side panel of PC case and locate PSU bay.
2. Mount PSU with fan facing intake or exhaust per case airflow design.
3. Connect modular cables only as needed: 24-pin ATX, 4+4-pin CPU, PCIe for GPU, SATA/Molex for drives.
4. Secure cables with ties for optimal airflow; utilize zero-RPM mode for silence.
5. Power on and verify voltages with multimeter if experienced; monitor temperatures.
6. For maintenance, dust fan monthly; check cables yearly. Pro tip: Use sleeved cables for aesthetics and airflow.
