Questions about this item

What limits the 550 W output when the supply runs continuously?

The 550 W rating is the continuous limit; sustained loads above that level will trigger protection.

How loud and hot does the unit get during all-day operation?

A built-in fan cools the supply; noise and temperature rise with load but stay within normal ATX tolerances.

Which ATX cables must already be present in the build?

A standard 24-pin motherboard connector and a 4+4-pin CPU connector are required.
