Dell OptiPlex 390 SFF System Board

This genuine Dell M5Dcd system board is designed as a direct replacement for the OptiPlex 390 Small Form Factor desktop. It restores full motherboard functionality to a compatible chassis using the original mounting points and connector layout. The multicolor printed circuit board arrives in new condition ready for installation.

Ideal for technicians repairing a failed OptiPlex

This board suits repair shops and owners fixing a specific OptiPlex 390 SFF system where the original motherboard has failed. It is not for builders assembling a new custom PC or users needing a different form factor such as tower or micro variants. Buyers requiring a board for any other Dell model or a different generation should look elsewhere.

Questions about this item

Which OptiPlex 390 SFF system board should I choose for my desktop?

The Dell M5Dcd board is built specifically for the OptiPlex 390 SFF chassis, so it matches the mounting points and connector layout of that model.

What does the 5.1 weight figure mean once the board is installed?

At 5.1 units, the board adds minimal mass to the small-form-factor case, keeping the overall system light enough for easy desk moves or wall mounting.
