SATA 15-pin to PCIe 6-pin adapter cable 8 in 2-pack

This pair of cables converts a spare SATA power connector on a power supply into a 6-pin PCIe plug for a graphics card. Each cable uses 18 AWG copper conductors and measures 8 inches end to end. The keyed male connectors on both sides lock in place to resist accidental disconnection. No tools or drivers are required for installation.

Builders adding a GPU to a PSU without native PCIe

The adapter works when the power supply has unused SATA leads and the graphics card accepts a single 6-pin input. It does not suit systems where the GPU requires an 8-pin or dual 6-pin connection. Buyers needing more than two adapter cables should look elsewhere. The short length limits routing options in full-tower cases.

18 AWG copper conductor gauge

The wire thickness is specified as 18 AWG, which is heavier than the 22 AWG sometimes used on similar adapters. This gauge determines how much current the cable can carry without excessive voltage drop. Verify that the graphics card’s power draw stays within the limits of a single SATA-sourced 6-pin connection before purchasing.

Questions about this item

Will the 18 AWG copper conductors need replacement under normal load?

The 18 AWG copper wire is rated for the current a SATA power connector can supply, so the cable itself does not wear out and requires no scheduled replacement.

What limits the power delivered to the graphics card through this adapter?

The SATA power connector on the power supply is the limiting factor; it provides less current than a native PCIe 6-pin connector, so the card's power draw must stay within the SATA connector's capability.

Does the cable generate noticeable heat when the GPU runs all day?

With 18 AWG copper and an 8 inch run, resistive heating is minimal under typical loads, and the short length keeps voltage drop and warmth low during continuous operation.
