Dell OptiPlex replacement PSU

This 240W unit replaces the original power supply in Dell OptiPlex 7040, 3650, 3040 and 3046 desktops. It fits the proprietary 220×82×62mm chassis used by those systems and provides the required P1 8-pin and P2 4-pin connectors. Buyers restoring or repairing one of these models can install it directly without adapter cables.

Swaps the factory unit when it fails

The supply takes the place of a Dell OEM unit that has stopped delivering stable power or has developed coil noise. The jump is worth it when the original PSU no longer holds voltage under load or when the system will not post. It accepts 100-127V at 7.0A and 200-240V at 3.5A, matching the input range of the factory part.

Steady 240W output under continuous load

Rated for 240W maximum output, the unit maintains its rails during extended workstation sessions rather than only in short bursts. The compact 220×82×62mm form factor limits airflow, so sustained operation depends on the case fan moving air across the supply. Systems that run compute tasks for hours will see consistent delivery within the rated envelope.

Questions about this item

What are the exact dimensions of the H240EM-00 to confirm it fits my Dell chassis?

The unit measures 220×82×62mm, matching the standard form factor for the Dell 7040, 3650, 3040 and 3046 models listed.

How do I connect the P1-8Pin and P2-4Pin cables during installation?

Align each keyed connector with its socket on the motherboard and press firmly until the latch clicks; the P1-8Pin supplies main power while the P2-4Pin provides CPU power.

Will the cooling fan need cleaning or replacement over time?

The internal fan draws air through the 220×82×62mm housing; periodic dust removal with compressed air keeps airflow steady for the 240W load.
