Questions about this item

How much power does the 500W rating actually deliver to the components inside a working PC?

The 500W rating is the maximum continuous output the unit can supply across all rails when installed in a standard ATX system.

What does the ATX form factor limit when fitting this supply into a case?

ATX dimensions fix the physical envelope, so the unit fits any case with a standard ATX PSU bay and uses the regular 24-pin and 4/8-pin motherboard connectors.
