Direct replacement for Dell Optiplex SFF

This Vszerda power adapter is built as a direct replacement for Dell Optiplex 3040 3046 3250 3650 3656 5040 7040 Small Form Factor desktops. It matches the original H240EM-00 B240NM-00 and related model numbers listed in the compatibility data. The unit ships new and each one is tested before shipment.

240W continuous power with dual ATX connectors

The adapter delivers a total of 240W maximum across its two outputs: an 8Pin ATX power connector and a 4Pin ATX power connector. AC input accepts 100-127V at 7A or 200-240V at 3.5A at 50-60Hz. This capacity covers the factory specification for the listed SFF chassis; systems that require higher wattage or additional PCIe power connectors will exceed what this unit provides.

Connector layout decides fit

The decisive specification is the combined 8Pin plus 4Pin ATX connector arrangement. Only Optiplex SFF models wired for this exact pin-out will work; tower or micro-tower variants with different power-header layouts cannot use this adapter. Verify the part number on the existing supply against the supported list before ordering.

Questions about this item

Will this 240W adapter power my existing Dell Optiplex 7040 SFF without changing cables?

Yes, it matches the original 240W rating and uses the same 8-pin and 4-pin ATX connectors fitted to the Optiplex 3040, 3046, 3250, 3650, 3656, 5040 and 7040 SFF chassis.

How can I verify the unit is delivering the rated 240W after installation?

The system will POST and run stable under load; the power supply has been tested before shipment and accepts 100-127V at 7A or 200-240V at 3.5A input at 50-60Hz.

Does the package include both the 8-pin and 4-pin cables, or must I buy a 4-pin cable separately?

The adapter comes with both the P1 8-pin ATX and P2 4-pin ATX connectors attached; no extra cables are required for the listed Optiplex SFF models.
