Dell Power Supplies Reference Guide
OEMs such as HP, Gateway, Compaq, and Dell often deviate from accepted PC power supply standards. Unique shapes, connectors, and wiring are all signs of a proprietary design. Below is the cross reference of popular Compaq computers and part numbers to the appropriate power supply upgrades or replacements.
Dell Optiplex Users: We have created a guide to help some Dell Optiplex users find power supplies for their model. The guide does not cover all Optiplex models (especially recently) but is a tool for many of the problematic application Optiplex designs from Dell. Please see the guide here: Click Here
