Dell OptiPlex 3020 7020 9020 SFF Compatibility

This new server power supply is built as a direct replacement for Dell OptiPlex 3020 7020 9020 and T7100SFF systems. It matches the original HU255AS-00 D255AS-00 D255ES-00 L255ES-00 L255AS-00 AC255ES-00 AC255ES-01 part numbers. The unit fits the small form factor chassis and restores reliable power delivery.

Suits owners of listed Dell SFF desktops

Builders working with other Dell models or standard ATX cases should look elsewhere because the physical dimensions and pinouts are specific to the listed small form factor platforms.

Questions about this item

How do I install the Supersuperuncle power supply into a Dell 3020 SFF chassis?

Remove the side panel, unscrew the old PSU bracket, slide this unit in until the connector seats firmly, then refit the screw and panel.

What maintenance will the internal fan need over time?

Blow dust from the intake vents every few months; if the fan becomes noisy or stops spinning, replace the entire power supply unit.
