Dell Optiplex Compatibility

This 240W ATX power supply is built for Dell Optiplex 790, 990, 3010, 7010 and 9010 desktops. It suits owners replacing a failed original unit or upgrading an ageing system with a compatible, efficient replacement.

Installation Notes

The unit follows the standard ATX form factor and uses the proprietary connectors required by the listed Optiplex models. Swapping it is straightforward if the chassis matches; the main issue arises when the case or motherboard pinout differs from the supported series.

Pre-Purchase Checks

Verify your exact Optiplex model number and confirm the existing power supply carries the AC240ES-01, 1GC38, 01GC38 or PCB016 part reference. Ensure the physical mounting points and cable routing match the original unit before ordering.

Questions about this item

How do I confirm the power supply is operating correctly once installed in my OptiPlex?

Check that the system boots normally, the 80 PLUS Gold efficiency rating is active, and the fan remains off during light workloads thanks to the Zero RPM Fan Mode.

What comes in the box and which cables or adapters must I purchase separately?

The unit ships as a 240 W ATX replacement for Dell OptiPlex 790, 990, 3010, 7010 and 9010 models; no extra cables are included, so reuse the existing motherboard and peripheral connectors from the original supply.

Which version should I choose if my chassis is a Dell OptiPlex 3010 versus a 7010?

Both the 3010 and 7010 are listed in the compatible model range, so the single 240 W AC240ES-01 unit fits either chassis without a different part number.
