Manufacturer description
Running a Dell Optiplex 8-pin motherboard off a standard ATX power supply normally means hunting for a proprietary Dell PSU. The COMeap 24 Pin to 8 Pin ATX PSU Power Adapter Cable solves that in one step: the 24-pin end seats in any standard ATX supply, and the 8-pin end feeds the Dell board's proprietary power header. That makes it the missing link for anyone rebuilding an Optiplex 3020, 7020, or 9020, a Precision T1700, or a PowerEdge T20/T30/T130 into a case with an off-the-shelf PSU. Build details are spelled out rather than implied: 1007-18AWG tin-coated copper conductors, 12 inches…
SpecPicks Verdict
SpecPicks scored COMeap 24 Pin to 8 Pin ATX PSU Power Adapter Cable using a rating × review-volume × price-fit model applied to published specs and reviews across the cables & connectors category. COMeap's cables & connectors lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for cables & connectors 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.
Frequently Asked Questions
Will this work with my Dell Optiplex 9020?

12 inches, or 30cm, measured excluding the connectors. A single self-adhesive tape strip is included to secure the run.
How much power can it handle?
COMeap rates the cable at a maximum of 1000 watts, using 1007-18AWG standard tin-coating copper wire. That covers a mid-range GPU added to an Optiplex or Precision build.
