Purpose & fit

This genuine Dell CV7D3 power module delivers 240 W in a Small Form Factor chassis. It is built as a direct replacement for OptiPlex 390, 790, 990, 3010, 7010 and 9010 SFF desktops. The unit includes a single cooling fan and uses the standard 24-pin motherboard connector. It restores factory power reliability to compatible business PCs.

Who it suits — and who should look elsewhere

IT teams maintaining supported OptiPlex SFF fleets will find a drop-in spare that matches the original specifications. Builders assembling custom systems or upgrading graphics cards should look elsewhere because this unit is keyed to proprietary Dell SFF mounting and cabling. It does not serve full-size ATX cases or boards that require auxiliary power connectors beyond the standard 24-pin interface.

Deciding specification

The 240 W maximum output in an SFF form factor is the single figure that determines fit. If the target chassis is one of the listed OptiPlex SFF models and the original PSU rating is 240 W, this module is the correct match. Any system needing higher wattage or a different physical layout cannot use this part.

Questions about this item

Will the single internal fan need cleaning or replacement over time?

The unit uses one built-in fan; periodic dust removal keeps airflow steady and extends its service life.

What is the maximum continuous output this 240 W SFF supply can sustain?

It is rated for 240 W maximum power, which is the ceiling for sustained loads.

How much heat and noise should I expect when the PSU runs all day in an OptiPlex SFF?

The single fan handles thermal duties at 240 W load, producing typical SFF-level airflow sound and case warmth.
