Product Description

This power connector cable converts a standard 4-pin peripheral power output to a 6-pin PCIe connector for graphics cards and other electronic equipment. High-conductivity 18 AWG copper wires and reliable crimped terminals ensure low-loss power transmission and stable electrical performance. The nylon housings with locking features provide secure mating with mating terminals, preventing accidental disconnection under vibration.

The wire harness is designed for easy routing inside PC cases and server chassis. Black and yellow power wires clearly distinguish ground and 12 V lines, simplifying installation and maintenance. Custom wire length, connector combinations, and pin configurations are available to match different PCB layouts, power supplies, and device interfaces.

Applications

Supplying 12 V power from desktop PC power supplies to 6-pin PCIe graphics cards.

Power adapter cable for workstation and server upgrades where additional GPU power connectors are required.

DC power transmission inside industrial PCs, mining rigs, and embedded control cabinets.

Replacement or customized harnesses for OEM system integrators and automotive/industrial electronic projects.

Precautions

Verify that the power supply can provide sufficient current on the 12 V rail before connecting high-power GPUs or other loads.

Check connector orientation and pin assignment; incorrect wiring may damage the graphics card, PCB, or power supply.

Do not exceed the rated current and temperature limits of the cable, connectors, or terminals.

Avoid excessive bending, pulling, or twisting of the wire harness during installation.

Ensure all connectors are fully inserted and locked before powering on the system; periodically inspect for loosened terminals or discoloration caused by overheating.
