Dell Optiplex 240W Power Supply

This genuine Dell H240AM-02 unit delivers 240W of continuous power for Optiplex 3040, 5040 and 7040 desktops. It accepts a universal 100-240V input at 50-60Hz, making it a direct replacement for the original factory supply.

Installation Notes

The supply uses the proprietary Dell form factor and connector layout, so it fits only the listed Optiplex chassis without adapter cables. A common issue is ordering this unit for a different Optiplex generation or a small-form-factor case where the physical dimensions and pin-out do not match.

Who Should Buy

It suits IT technicians and owners restoring a compatible Optiplex 3040, 3650, 3656, 5040 or 7040 system to factory specification. Buyers needing higher wattage for discrete graphics upgrades, or those with non-Dell motherboards requiring standard ATX pin-outs, should look elsewhere.

Questions about this item

How can I confirm the H240AM-02 is working after installing it in my Optiplex?

The system should power on normally and the rear PSU fan should spin steadily when the 240 W unit is seated correctly in a compatible Optiplex 3040, 5040, 7040, 3650 or 3656 chassis.

What comes in the box with this Dell H240AM-02 and what must I source separately?

The unit ships as the power supply module only; the IEC mains lead, mounting screws and any chassis-specific cable adapters are not included and must be supplied separately.

Which part numbers identify the correct 240 W version for my Optiplex 3040, 5040 or 7040?

Match the MPN list — 0H62JR, CN-0H62JR, 4GTN5, DHVJN, 3RK5T or H62JR — to your service tag; all refer to the same H240AM-02 240 W supply for those models.
