Compatible Dell SFF Models

This 180 W power supply is built for the Dell OptiPlex 3420 and 7050 small form factor chassis. It replaces part numbers 82DRM and 082DRM directly. The unit is new condition and was first listed by the manufacturer in April 2026. It suits owners of those specific SFF systems needing a direct replacement.

Form Factor Fit

The supply matches the proprietary dimensions and connector layout required by the 3420 and 7050 SFF cases. No adapter cables or bracket modifications are needed for installation. The bundled mounting hardware aligns with the existing screw points in those chassis. This eliminates guesswork during the swap.

Pre-Install Checks

Verify the chassis label reads OptiPlex 3420 or 7050 SFF before ordering. Confirm the existing unit carries part number 82DRM or 082DRM. Ensure the system power requirement does not exceed 180 W. Other Dell SFF models or tower variants will not accept this supply.

Questions about this item

Will the internal fan in this 180W unit need periodic cleaning or replacement?

The 180W power supply uses an internal cooling fan; dust buildup over time can reduce airflow, so occasional cleaning with compressed air is recommended to maintain reliable operation.

What component reaches its limit first when this 180W supply runs continuously at full load?

The 180W maximum output rating is the primary limit; sustained loads at or near this level will stress the internal components and trigger protection circuits before any other factor.

How much heat and noise does this 180W supply produce when powering a Dell 3420 or 7050 SFF all day?

At typical office loads the 180W unit runs quietly with modest heat; under sustained heavy demand the fan speed increases, raising audible noise and case temperature proportionally.
