Questions about this item

How does the 250 W rating translate once the PSU is installed in a Vostro 230 SFF?

The 250 W maximum power is the total continuous output the unit can deliver to the motherboard, drives and add-in cards inside the small-form-factor chassis.

What does the 24-pin connector cap in practice?

The 24-pin ATX connector supplies the motherboard main power rail and limits the combined draw of CPU, memory and onboard devices to what the 250 W unit can sustain.
