It delivers 520 watts of continuous power to matched chassis and backplane configurations. System integrators and IT teams use it as a direct replacement or spare in compatible rack environments.

Questions about this item

How much noise and heat does the 520 W unit produce under continuous load?

The 520 W server supply uses an internal fan that spins up with load; expect typical server-grade airflow noise and warmth at full output.

What cables or rails must I already have to install this 3Y YH-6521B supply?

You need the matching 3Y chassis slot and the proprietary power backplane connector that the YH-6521B series plugs into.
