Dell OptiPlex SATA Power Cable

The SMUGDESK 7G26H cable is a direct OEM replacement for Dell OptiPlex 3040, 5040 and 7040 MT tower desktops. It connects the motherboard power header to SATA hard drives, SSDs and optical drives. The part number CN-07G26H matches the factory specification for these specific models.

IT Technicians and Storage Upgrades

This cable suits technicians performing maintenance, users adding extra SATA storage devices, or anyone replacing a damaged original cable in the listed OptiPlex towers. It is not for builders working on non-Dell chassis, laptops, or systems lacking the proprietary motherboard power header.

Proprietary Motherboard Connector

The single deciding specification is the custom wiring layout built exclusively for the Dell OptiPlex 3040, 5040 and 7040 MT motherboard header. If the target system does not use this exact connector, the cable will not fit or function.

Questions about this item

Will the 7G26H cable need replacing if the connectors loosen from chassis vibration?

The moulded connectors are designed to resist accidental disconnection caused by vibration, so routine replacement is not expected under normal use.

What is the first limit reached when running multiple SATA drives continuously on this cable?

The cable uses oxygen-free copper conductors to maintain steady power delivery and reduce power loss during continuous operation.

Does the 7G26H generate noticeable heat or noise when powering drives all day in an OptiPlex 7040 MT?

As a passive power cable it produces no noise, and the premium copper wiring minimises heat build-up during sustained use.
