HETAI Digital Technology Co.,Ltd 20cm Dual 15Pin SATA Male to PCIe 8Pin (6+2) Male Power Cable

SKU CH-04R1-C0GR1

Converts dual SATA 15-pin power connectors to a single PCIe 8-pin (6+2) graphics card connector using 18AWG wire over 20cm length

  • Connector TypeMicro USB to USB A
  • Dual SATA power feeds an 8-pin GPU connector
  • 20 cm cable keeps multi-GPU wiring tidy
  • 18 AWG conductors handle high graphics-card current
  • Converts two 15-pin SATA plugs to one 6+2 PCIe plug
  • New cable solves missing 8-pin power on cost-saving PSUs

Dual SATA to PCIe 8-pin adapter

This 20 cm cable converts two 15-pin SATA power connectors into a single PCIe 8-pin (6+2) plug for a graphics card. It targets builders whose power supply lacks native 8-pin leads or who are running multiple cards on one unit. The 18 AWG wires handle the combined 12 V current required by high-end GPUs. A single SATA connector cannot supply enough amperage on its own.

Installation notes and common pitfalls

Plug both SATA ends into separate peripheral cables from the PSU; using only one STA connector risks melting the wire or tripping protection. Route the short 20 cm length carefully so the stiff 18 AWG cable does not strain the GPU socket. Verify that the 6+2 segment matches your card’s 8-pin or 6-pin requirement before seating it firmly. Do not daisy-chain additional adapters on the same rail.

Check your power supply before ordering

Confirm the PSU has at least two unused SATA power leads on independent cables if possible. Ensure the unit’s 12 V rail rating can sustain the graphics card’s total draw through this adapter. The cable adds no voltage regulation, so the PSU must already deliver stable 12 V power. Buyers needing longer reach or a single-cable solution should look elsewhere.

Questions about this item

How can I confirm the 18AWG dual SATA-to-PCIe cable is delivering stable power after connecting it to my graphics card?

Check that the card powers on without shutdowns under load and that the 15-pin SATA connectors stay firmly seated in the PSU.

What comes with the 20 cm 18AWG dual 15-pin SATA to 8-pin (6+2) cable and what must I supply?

The package includes one 20 cm cable with dual 15-pin SATA plugs and an 8-pin (6+2) PCIe plug; you must provide a PSU with two free SATA power ports.

Which version of the 18AWG dual SATA to 8-pin (6+2) cable should I choose for a high-end GPU that needs extra 12 V current?

The single 20 cm 18AWG model with dual 15-pin SATA connectors is built to supply the required 12 V current for such cards.
