8.04 in SATA to PCIe power adapter

This 8.04 in cable converts a SATA 15-pin power connector into a 6-pin PCI Express plug. It is built for builders whose power supply lacks native PCIe connectors or has too few for the installed cards. The white cable carries model numbers 8494 and 108494.

Who should use this adapter

Suits anyone adding a graphics card or other PCIe device to a system with spare SATA power leads but no free PCIe power outputs. Not for builders who need more than one PCIe connector from a single SATA lead, or who require an 8-pin PCIe plug instead of the 6-pin provided here.

The deciding specification

The cable delivers a 6-pin PCI Express power connector from one SATA 15-pin source. If your component needs an 8-pin PCIe connector or draws more power than a single SATA line is rated for, this adapter will not meet the requirement.

Questions about this item

How do I connect the 8.04 in SATA 15-pin to 6-pin PCIe cable without damaging the connectors?

Align the SATA 15-pin plug with the power supply's SATA port and press straight in until it clicks, then seat the 6-pin PCIe end into the graphics card. Forcing either connector at an angle bends the pins.

Will the SATA 15-pin plug or the 6-pin PCIe end wear out first with repeated swaps?

Both connectors are rated for standard mating cycles; the SATA 15-pin side typically sees less insertion force, so the 6-pin PCIe end usually shows wear first if the cable is moved between cards often.

What limits the cable when a graphics card draws full load continuously?

The 0.67 ft length and wire gauge set the voltage-drop ceiling; under sustained max draw the 6-pin PCIe connector's current rating is reached before the cable insulation becomes a concern.
