Dell OptiPlex 9020 SFF 255W power supply

This 255W desktop power supply is built for the Dell OptiPlex 9020 small form factor chassis. It provides a direct replacement for the original HCWV2 unit. The non-modular design includes fixed cables and a single cooling fan. Condition is new and it fits the proprietary Dell connector layout.

Suits owners replacing a failed OptiPlex 9020 SFF

This unit suits anyone restoring a Dell OptiPlex 9020 SFF to working order with an exact-match 255W power supply. Builders assembling a custom ATX system should look elsewhere because the connector pinout and physical dimensions are proprietary to this Dell platform. It does not support standard ATX motherboard power requirements.

Proprietary 8-pin Dell connector decides fit

The single most important specification is the proprietary 8-pin motherboard connector unique to Dell OptiPlex 9020 SFF systems. Standard 24-pin ATX power supplies will not connect to this motherboard without an adapter board. Verify the existing unit carries the HCWV2 part number before ordering to ensure the connector matches.

Questions about this item

How much heat and noise does the 255 W Dell HCWV2 produce when running continuously in an OptiPlex 9020?

The unit delivers up to 255 W through a single internal fan; under sustained load the fan spins faster, increasing audible airflow and exhaust heat inside the small-form-factor chassis.

Which cables and connectors are already attached to the HCWV2 so I know what the OptiPlex 9020 motherboard needs to supply?

The power supply is non-modular, so all leads — including the 8-pin motherboard connector — are permanently fixed; only the cables shown in the product images are present.

Will the HCWV2 255 W unit fit and power an older OptiPlex 9020 SFF that previously used a lower-wattage supply?

Yes, it is built for the OptiPlex 9020 small-form-factor case and provides the same 8-pin interface, so it replaces the original supply directly.
