How to use

Install the FUJITSU PY-PU902 into a compatible desktop or workstation case following the case manufacturer’s mounting instructions. Connect the main 24-pin ATX and 4/8-pin CPU power connectors to the motherboard, then attach modular cables to graphics cards, storage devices and peripherals as required. Ensure all connections are secure before powering on the system. Verify system stability after installation and monitor voltages during initial operation if your monitoring tools support it.

Recommendations

Use appropriately rated cables and a case with sufficient ventilation. For systems with multiple high-power components, allow some power headroom and ensure the cooling within the case is adequate to maintain stable operation. Follow safety guidelines for grounding and static discharge when handling the power supply.
