Compatible Dell SFF systems

This 255W power adapter replaces the original unit in Dell Optiplex 3020, 7020 and 9020 Small Form Factor desktops as well as the Precision T1700 workstation. It matches the listed part numbers including H255ES-00, D255AS-00 and NT1XP for a direct swap.

Thermals and power draw

The adapter accepts 100-240V input at 5.0A across 50Hz-60Hz mains with a 265W maximum input rating. It delivers the 255W output the chassis expects through its native connectors without requiring additional cooling changes.

Connectors and daily fit

Two fixed cables provide an 8-pin ATX power plug and a 4-pin ATX power plug that align with the motherboard headers in the supported SFF cases. Builders needing a different pin layout or higher wattage for upgraded components will need a different supply.

Questions about this item

How do I install the Vszerda 255W adapter in a Dell Optiplex 3020 SFF and which connector step is often missed?

Remove the chassis cover, slide the unit into the SFF bay, secure the mounting screws, then attach both the P1 8-pin ATX and P2 4-pin ATX connectors; the 4-pin CPU plug is the one most often forgotten.

What maintenance will this 255W power supply need over time?

Keep the intake vents clear of dust; use compressed air every few months to prevent heat build-up that stresses the internal components.

What limit appears first when this adapter runs at full 255W load continuously?

The 265W maximum input rating leaves only a small overhead, so sustained full-load operation pushes the unit to its thermal and current ceiling first.
