SpecPicks scored Dell Optiplex 390 790 990 3010 SFF Desktop Power Supply CCCVC… using a rating × review-volume × price-fit model applied to published specs and reviews across the power supplies category. Dell's power supplies lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Common buyer scenarios for power supplies of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase. Prices and stock are set by the retailer and may have moved since this page was last updated.
