Questions about this item

How do I install the 350W ATX power supply in my chassis?

Secure the unit with the standard four mounting screws, connect the 24-pin ATX motherboard cable and the CPU power cable, then attach the remaining leads to your drives and graphics card.

Replace the fan when bearing noise appears or airflow drops enough to raise internal temperatures above safe limits.
