商品問答

What does the 240 W rating mean once the unit is installed in an OptiPlex SFF?

It is the maximum continuous output the supply can deliver to the motherboard, drives and add-in cards in the listed small-form-factor desktops.

What interface standard does the 24-pin ATX connector follow and what does it cap in practice?

The 24-pin ATX connector follows the AT specification and limits total system draw to 240 W.

What physical clearance does the power supply need to fit the OptiPlex 3010, 7010 or 9010 SFF chassis?

It is built to the same dimensions as the original H240AS-00 and L240AS-00 units used in those models.
