Questions about this item

What is the maximum continuous power output the DPS-450CB-1 can deliver before its protection circuits activate?

The unit is rated at 450 watts; sustained loads above that level will trigger the built-in over-power protection and shut the supply down.

How loud is the cooling fan when the power supply runs at full load for an extended period?

The internal fan spins faster as load increases; at full 450-watt output it produces noticeable but typical server-grade airflow noise.
