Dell OptiPlex power replacement cable

This 240 W internal cable fits OptiPlex 3040, 3046, 3650, 5040 and 7040 small-form-factor and micro-tower chassis. It replaces the AC240AM-01 power adapter and connects directly to the motherboard using a 6-pin and a 4-pin connector. The part is new and ready for installation. Builders restoring or upgrading these specific Dell desktops will find the correct pin-out and length.

Not for systems outside the listed OptiPlex models

The fixed 6-pin and 4-pin layout does not match other Dell power supplies or third-party motherboards. Buyers needing a standard ATX 24-pin connector, a different wattage rating or a modular cable set must choose a different product.

Questions about this item

Does the 240W cable itself wear out and need replacement?

The cable is a passive assembly with no moving parts; it does not degrade under normal use and only needs replacement if the connectors or insulation are physically damaged.

What is the first limit reached when the cable runs at 240W continuously?

The 240W rating is the sustained power limit; exceeding it would overheat the conductors, so the cable’s own rating is the first constraint under continuous load.
