SKU CH-W7XS-WT0GX

290W ATX power supply tested working for OptiPlex 3020, 7020, 8020, 9020, T1700 and 3670 desktops with 8-pin connector

  • TypeATX
  • Tested working for immediate reliability
  • 290W output powers compatible OptiPlex desktops
  • 8-pin connector fits listed OptiPlex models
  • ATX form factor suits standard chassis builds

Compatible Dell OptiPlex replacement

This 290 W ATX power supply is built as a direct replacement for Dell OptiPlex 3020, 7020, 8020 and 9020 desktops as well as the T1700 and 3670 models. It delivers the factory-spec 8-pin connector required by those chassis. Buyers needing higher wattage or standard 24-pin ATX pin-outs for custom builds cannot use this unit.

Tested thermals and power draw

Each unit is test-working before shipment, confirming stable output at the rated 290 W under normal office loads. The original cooling design maintains acceptable temperatures and noise levels inside the supported OptiPlex cases. No efficiency certification or fan-curve data is provided by the supplier.

Spurningar um þessa vöru

How do I install the 290W ATX unit in an OptiPlex 7020 and which 8Pin connector step is often missed?

Fit the supply into the chassis, secure the mounting screws, then plug the 8Pin motherboard connector firmly until it clicks; the second 8Pin CPU power lead must also be seated or the system will not post.

What maintenance will the 290W ATX supply need after extended use in an OptiPlex 9020?

Clean dust from the intake grill and fan blades every six months; replace the unit if voltages drift under load or the fan develops bearing noise.
