Questions about this item

Will the fan in this 400W ATX power supply need replacement after extended use?

The fan is a moving part and will eventually wear out; expect to replace it once bearing noise or reduced airflow appears after prolonged operation.

What thermal limit appears first when this 400W unit runs at full load continuously?

Internal component temperature reaches its safety threshold before the 400W rating can be sustained indefinitely, triggering protective shutdown.
