240W SFF Power Supply Replacement

This 240W desktop power supply unit replaces original Dell units in OptiPlex 390, 790, 960, 990, 3010, 7010 and 9010 Small Form Factor systems. It matches part numbers including H240AS-00, AC240AS-00, L240AS-00, AC240ES-00, H240ES-00 and DPS-240WB. The unit is tested before shipping and carries an 18-month warranty. It is intended for owners of those specific SFF models needing a direct replacement.

Form Factor and Cable Length Limits

This supply fits only Dell OptiPlex Small Form Factor chassis and will not work in Mini Tower, Desktop or Ultra Small Form Factor variants. The P1 main cable measures approximately 3 inches, far shorter than the 12.5 inch length found on some other units. That short reach restricts routing inside the tight SFF enclosure and may not reach connectors on non-standard boards. Verify your chassis type and cable routing path before ordering.

Compatibility Checks Before Ordering

Confirm your system is one of the listed OptiPlex SFF models and not a MT, DT or USFF version. Cross-reference the original part number against the compatible list: 3WN11, 709MT, 592JG, 66VFV, CCCVC, RV1C4, J50TW, 2TXYM or the H240, AC240, L240, D240 and DPS-240WB series. Buyers with Mini Tower, Desktop or Ultra Small Form Factor OptiPlex units cannot use this supply.
