240W SFF replacement supply

This new 240W server power supply replaces Dell OptiPlex 3040, 5040, 7040, 3650 and 3656 small-form-factor units. It matches part numbers 3RK5T, 0G2JM, 0M2WH, 379F0 and 2P1RD. The unit delivers up to 240W of continuous power for compatible desktops.

Check model and part number first

Verify that your OptiPlex chassis is one of the listed SFF models before ordering. Cross-reference the existing supply label with the five Dell part numbers or the model codes L240ES-00, B240AM-00, HU240AM-00, AC240AM-00 or H240AM-02. Confirm the 100-240V 4.0A 50-60Hz input matches your mains supply.

Standard ATX connectors for SFF bays

The supply uses the proprietary connector layout required by these OptiPlex SFF cases, so it fits the existing mounting bracket without modification. Cabling reaches the motherboard and drive headers in the compact chassis. No adapter harnesses are included, so reuse the original cable routing clips during installation.

Questions about this item

What cables or brackets come with the 240W power supply and what must be sourced separately?

The unit is supplied as the power supply module only; any mounting screws, power cords or Dell-specific brackets needed for the OptiPlex SFF chassis have to be obtained separately.

Several part numbers are listed — 3RK5T, 0G2JM, 0M2WH, 379F0 and 2P1RD — which one should I order?

All five part numbers refer to the same 240W unit compatible with OptiPlex 3040, 5040, 7040, 3650 and 3656 SFF models; order whichever number matches the label on the unit you are replacing.

What does the 240W rating mean when the supply is installed in an OptiPlex 3040 SFF?

It is the maximum continuous output the supply can deliver to the motherboard, drives and add-in cards; the 100-240V 4.0A 50-60Hz input lets it operate on standard mains voltages worldwide.
