Questions about this item

Does the 550 W rating suit the server chassis I plan to install it in?

The unit delivers up to 550 W of AC power; match that figure against your chassis power budget to confirm it covers peak load.

What does the 550 W headline figure mean once the supply is in a real machine?

It is the maximum continuous AC output the supply can provide to the system; actual draw will vary with the components installed and their workload.
