Compatible Dell OptiPlex SFF Replacement

This 255W power supply fits Dell OptiPlex 3020 9020 7020 small form factor desktops. It replaces part numbers T4GWM VPMVK NT1XP FP16X YH9D7 3XRJ0 and model numbers AC255AS-00 D255AS-00 L255ES-00 L255AS-00 H255AS-00 H255ES-00 AC255ES-00 HU255ES-00. The unit is new and rated for 255W maximum output.

Input Voltage Range and Frequency Limits

The PSU accepts AC input from 100V to 240V at 4.6A across 50Hz to 60Hz. This range covers standard mains supplies in most regions without manual switching. The 255W ceiling defines the total power available to all internal components combined. Systems with many drives or add-in cards may exceed this budget.

Check Form Factor and Part Number Match

Verify the chassis is a small form factor OptiPlex 3020 9020 or 7020 before ordering. Tower or micro versions use different PSU shapes and connectors. Confirm the existing unit carries one of the listed part or model numbers to ensure connector pinout and mounting holes align.
