240 W Small Form Factor power supply

This is a genuine Dell H240ES-01 unit rated at 240 W and built for Small Form Factor OptiPlex desktops. It accepts 100-240 V input at 3.6 A and 50-60 Hz. A single fan provides cooling through the standard chassis opening. The unit ships new and ready to install.

Builders repairing or upgrading those listed Dell Small Form Factor models can use this supply directly. Systems that require higher wattage, a different form factor, or proprietary connectors not listed here will need another solution. Buyers with tower or micro-tower chassis should verify fit before ordering.

20-pin and 24-pin main connector configuration

The supply provides both a 20-pin and a 20+4-pin (24-pin) ATX main connector plus the Dell-specific pinout used by the compatible OptiPlex lines. If your motherboard demands a different main-power layout or additional GPU power cables, this unit will not meet that requirement.

Questions about this item

How can I confirm the H240ES-01 is working after installation?

The system powers on normally, the single fan spins, and the Dell OptiPlex 3010, 7010 or 9010 completes POST without power-related errors.

What comes in the box and what must I source separately?

The unit includes the 240 W SFF power supply with one fan; you must reuse the existing 20-pin, 20+4-pin and 24-pin cables from the chassis.

Which MPN matches my OptiPlex 390, 790 or 990?

Match the sticker on your old supply to VMRD2, 0VMRD2, CN-0VMRD2, 592JG, 2TXYM, N9MWK, JNPVV, 1GC38 or 3WN11 — all refer to the same H240ES-01 model.
