How to use
Install the Silverstone FX500 into a compatible Flex ATX or small form factor chassis following the chassis manufacturer’s mounting instructions. Connect the 20+4 pin ATX cable to the motherboard main power socket and attach SATA power connectors to storage devices as required. Ensure the AC input is within the specified 90–264 V range and connect to a properly grounded power source. Allow clearance for airflow around the 40 mm fan and route cables to avoid obstructing internal cooling paths.
Usage recommendations
For reliable long-term operation, maintain ambient temperatures within the server or chassis manufacturer’s specified limits, keep dust away from the 40 mm fan, and avoid operating the PSU near its maximum rated load continuously. Use a surge protector or uninterruptible power supply (UPS) when deploying critical systems.
