Proprietary Mini 8Pin to SATA Power Cable

This internal cable converts the proprietary Mini 8Pin power header on Dell OptiPlex 3040, 5040 and 7040 MT tower power supplies into standard SATA power connectors. It enables power delivery to additional SATA hard drives, SSDs or optical drives inside the chassis. The design matches OEM part numbers CN-07G26H, 07G26H and 7G26H for exact fit replacement. Builders upgrading storage or replacing a damaged original cable use this adapter.

Multiple SATA Ports for Storage Expansion

The cable splits the single Mini 8Pin output into several SATA power ports, allowing simultaneous connection of multiple drives without extra adapters. Reinforced molded connectors maintain tight contact and resist vibration inside the case, preventing intermittent power loss that can cause drive detection failures or boot errors. Steady current transmission supports continuous desktop operation for optical drive installation and multi-drive configurations.

Direct Plug-and-Play Installation

Installation requires no modification: plug the Mini 8Pin connector into the PSU terminal and attach SATA devices to the power ports. The precision-molded ends ensure proper alignment with the proprietary header. The main limitation is that the cable only fits the listed OptiPlex MT tower models; it will not work with small form factor, micro tower or other Dell chassis that use different power supply interfaces. Builders needing power for non-SATA devices or other systems cannot use this cable.

Questions about this item

Does the Mini 8Pin connector on this cable wear out after repeated drive swaps?

The precision-molded Mini 8Pin and SATA connectors are reinforced to resist vibration and maintain tight contact during long-term desktop operation.

Will the cable handle continuous power draw from multiple drives without voltage drop?

It is built to OEM specification with high-quality conductive wire core for stable continuous power delivery that prevents disk detection failures.

How much heat does the cable generate when powering drives all day in a tower case?

The cable is designed for steady current transmission during sustained desktop use; no active cooling is required for normal operation.
