SKU CH-KC7F-2FSTD

  • TypeATX 12V
  • Maximum Power305 W
  • 305 W output powers the OptiPlex 980 reliably
  • ATX12V standard fits the desktop chassis precisely
  • Internal form factor installs without external adapters
  • Dell-engineered unit matches original power specifications exactly
  • New condition delivers full rated performance from day one

Dell OptiPlex 980 power supply

This 305 W ATX12V unit is built as a direct replacement for the Dell OptiPlex 980 desktop computer. It delivers the factory-specification power envelope required by that platform. The internal form factor matches the original chassis mounting points and connector layout.

305 W capacity and headroom

The supply provides 305 W of continuous output power for the system board, processor, memory and integrated graphics. It comfortably handles the standard OptiPlex 980 configuration as shipped by Dell. Headroom diminishes when discrete graphics cards or additional drive arrays are added beyond the original specification.

Replaces the original OptiPlex 980 unit

This unit replaces a failed or degraded factory power supply in the OptiPlex 980 without modification. The jump is worth it when the existing supply shows instability, voltage drift or complete failure. It is not for builders adapting the chassis to non-standard motherboards or higher-wattage components.

Questions about this item

Will the 305 W ATX12V unit power my existing OptiPlex 980 motherboard without adapter cables?

The supply is built for the OptiPlex 980 chassis and uses the standard ATX12V connector layout that the 980 motherboard expects, so it plugs in directly.

How can I verify the 305 W PSU is delivering stable voltage after installation?

Enter the BIOS hardware monitor or run Dell's built-in diagnostics; both report the 12 V rail in real time so you can confirm it stays within specification under load.

Does the box include the mounting screws and power cord, or must I source them separately?

The unit ships as an internal ATX12V module only; mounting screws and the IEC mains cord are reused from the original OptiPlex 980 or purchased separately.
