Questions about this item

How loud is the EFRP-553V3 when it runs at 550 W continuously?

The 550 W server supply uses an internal fan that spins faster under full load, so expect noticeable airflow noise during sustained 550 W operation.

What existing hardware must I have to install the NF290D2/NF5220 unit?

You need an ATX-compatible case and motherboard with standard 24-pin and CPU power connectors to use this 550 W supply.
