255 W power adapter for Dell Optiplex SFF

This Vszerda unit replaces the H255ES-00 power supply in Optiplex 3020, 7020 and 9020 as well as Precision T1700 small-form-factor systems. It delivers up to 255 W of DC output from a 100-240 V AC input rated at 4.6 A. The adapter is new and tested before shipment.

Check model and connector match before ordering

Verify that your existing chassis uses the H255ES-00, D255AS-00 or any listed compatible part number such as YH9D7 or R7PPW. Confirm the motherboard requires both an 8-pin ATX power connector and a 4-pin ATX power connector. Ensure the AC input range of 100-240 V at 50-60 Hz matches your local mains supply.

Fits Dell SFF chassis with dual ATX power leads

The supply mounts inside the small-form-factor case and provides the two ATX power cables needed by the motherboard. Its 255 W capacity supports the original system configuration without requiring additional power cables. No extra connectors or adapters are included beyond the P1 and P2 leads.
