Dual SATA to PCI-E 8-Pin Adapter Cable

This set includes two 20 cm adapters that convert two SATA 15-pin power connectors into a single PCI-E 8-pin (6+2) plug. It is intended for builders who need to power a graphics card from a power supply that lacks native PCI-E cables. The 100% copper conductors and UL certification support reliable power delivery.

Suits PSUs without native PCI-E connectors

The cable suits systems where the power supply offers spare SATA power leads but no dedicated PCI-E outputs, enabling a GPU upgrade without replacing the PSU. It is not for builders whose power supply already provides the required 8-pin connectors or who need to power cards drawing more than 320 W. Users requiring longer cable runs for large cases should look at alternative lengths.

20 cm length and dual SATA source

Each adapter measures 7.87 inches (20 cm) from the SATA plugs to the PCI-E connector, a fixed reach that determines whether it fits your component layout. The dual SATA design draws power from two separate 15-pin headers to supply the 8-pin (6+2) graphics card input. Verify that your power supply has two free SATA connectors and that the 20 cm span reaches your card before purchasing.

Questions about this item

Should I use one or both SATA 15pin connectors to power a graphics card?

Use both SATA 15pin connectors for a single PCI-E 8pin connection; each cable splits into two SATA plugs to supply the required current.

Will this adapter safely deliver the 320w mentioned for an RX 6900?

The adapter is rated for up to 320w; ensure your power supply SATA connectors and wiring can handle that load continuously.

What does the 6+2 pin PCI-E connector actually fit?

The 6+2 pin male connector fits both 6-pin and 8-pin PCI-E graphics card sockets, providing compatibility with either configuration.
