Dual SATA to PCIe Power Adapter

This BUCIER cable converts two 15-pin SATA power connectors into a single 8-pin (6+2) PCIe connector. It targets builders who need to power a graphics card when the power supply lacks native PCIe cables. The 7.4in length suits tight routing between drives and the GPU.

Installation Notes and Common Issues

The 18AWG pure copper conductors are thick yet flexible for easy bending inside a case. Users must align the 6+2 pin plug correctly and hold the device steady while seating it to avoid bent pins or shorts. The braided sleeve adds durability but can snag on sharp case edges if not routed carefully.

SATA Power Rail Limitations

Each SATA connector draws from a 12 V rail rated for limited current, so the adapter suits mid-range cards rather than high-wattage models. The dual-SATA design spreads load across two rails for better stability. It cannot replace a dedicated PCIe cable on power supplies that already provide one.

Questions about this item

How can I confirm the 18AWG cable is delivering stable power to my GPU after connecting the dual 15-pin SATA plugs?

The system should boot without crashes and the graphics card fans should spin normally, showing the adapter is drawing from two 12 volt rails as intended.

What comes in the 2-pack and do I need any extra connectors for a 6-pin video card?

The box contains two 7.4in dual 15-pin SATA male to 8-pin PCIe female adapter cables; the 8-pin end splits to 6+2 so no extra parts are required for a 6-pin GPU.

Which version should I choose if my power supply only has 15-pin SATA ports free?

This dual 15-pin SATA to 8-pin (6+2) PCIe cable is the correct version to convert two SATA power connectors into one GPU power plug.
