Two black SATA power adapter cables with 8-pin and 15-pin connectors

Manw

Manw 2 Pack 8 Pin PCIe to 15 Pin SATA Power Adapter Cable

SKU CH-SN0N-09G2E

Converts a 15 pin SATA power output to an 8 pin PCIe graphics card input, includes two adapters for single or dual GPU setups

  • Powers graphics cards using spare SATA ports
  • Pack of two adapters suits single or dual GPU builds
  • Copper conductors minimise voltage drop under heavy load
  • Reinforced moulded joints resist wear from repeated insertion
  • Plug-and-play design needs no drivers or tools

Dual 8-Pin PCIe to SATA Adapters

This two-pack converts spare 15-pin SATA power connectors from a power supply into 8-pin PCIe plugs for discrete graphics cards. It suits builders upgrading a GPU on an older PSU that lacks enough native PCIe cables. The adapters are plug-and-play with no drivers required.

SATA Power Output Limitation

Each SATA port on a power supply is rated for a finite current that is lower than a dedicated PCIe connector can deliver. Drawing the full load of a high-end graphics card through these adapters can exceed the SATA circuit capacity and cause instability or shutdowns. They are not intended for cards that demand more power than the SATA rail can safely supply.

15-Pin SATA Source Connector

The adapter only works if the power supply has an available 15-pin SATA power socket to spare. Systems with fully occupied SATA ports or modular PSUs missing the corresponding cable cannot use this kit without additional changes.

Questions about this item

Should I get the 2-pack or would a single cable be enough for my graphics card?

The 2-pack covers both single and dual GPU setups, so you have a spare if your card needs two 8-pin connectors or for a future upgrade.

How does converting a SATA 15Pin output to an 8Pin PCIe input affect power delivery to the GPU?

High-conductivity copper wires and reinforced joints keep voltage stable under heavy load, preventing the drops that cause crashes or throttling.

What does the SATA 15Pin interface limit when powering an 8Pin PCIe graphics card?

The cable itself is rated for the conversion, but the total power available still depends on the SATA rail capacity of your specific power supply.
