Questions about this item

How do I install this 500W power supply into an HP 870 desktop and which connector alignment step is often missed?

Align the PS-4501-2 unit with the chassis rails, secure the four mounting screws, then attach the 24-pin ATX and 4-pin CPU cables; the step often missed is fully seating the 24-pin clip until it clicks.

What maintenance will this PS-4301-2 unit need later and when should the internal fan be cleaned?

The PS-4301-2 requires no scheduled part replacement; clean the intake fan with compressed air every six to twelve months depending on dust levels to maintain airflow.
