Power adapter for PCIe video cards

This Vszerda cable converts a 15-pin SATA power connector from the supply into an 8-pin PCIe connector for a graphics card. Each pack contains two 20 cm cables built with 18 AWG copper conductors. The adapter suits builders whose power supply lacks native 8-pin leads or needs extra connections for an upgrade.

Thermals and power handling

Rated for a maximum of 120 W, the 18 AWG copper wire and UL1007 insulation deliver stable current without excessive heat under normal loads. The tangle-free design keeps airflow paths clear inside the chassis. No active cooling or fan is involved, so the cable adds no acoustic noise to the system.

Build integration

Male-to-female terminals plug directly between the supply’s SATA leads and the card’s 8-pin socket, requiring no tools or soldering. The short 20 cm length reduces clutter in tight cases while still reaching most routing paths. Compatible with Windows, Linux and Mac platforms, the pair gives a spare for multi-GPU setups or future repairs.

Questions about this item

How do I install the 8-pin PCIe to 15-pin SATA power cable and what step is often missed?

Connect the 15-pin SATA male plugs from the power supply into the cable's SATA connectors, then attach the 8-pin PCIe female end to the graphics card. The step often missed is ensuring both SATA connectors are fully seated to deliver the rated 120W.

What maintenance or replacement will this 20cm adapter cable need over time?

Inspect the 18 AWG copper conductors and connector pins periodically for dust buildup or oxidation. Replace the cable if the insulation shows cracking or if the SATA or PCIe connectors become loose, as the 120W rating depends on clean, tight contacts.

What limit appears first when this cable runs a graphics card under sustained load?

The 120W maximum power rating is the first limit reached under sustained use. Drawing more than 120W through the 18 AWG conductors risks voltage drop and overheating, so the connected GPU must stay within that ceiling.
