Product Description
This PCIe GPU power connector cable is designed for stable power transmission between the power supply unit and high-performance graphics cards or accelerator cards. The harness uses bundled oxygen-free copper wire with 18AWG conductors and precision-stamped terminals to minimize electrical loss and temperature rise under continuous load.
Each connector housing is molded from heat-resistant thermoplastic and fitted with high-reliability male/female power terminals for secure mating with PSU and GPU sockets. The outer braided sleeve keeps multiple wires neatly organized, enhances abrasion resistance, and gives a clean appearance for visible PC builds or server racks.
The connector cable can be customized for different PSU brands, server backplanes or adapter boards, including changes to pin definition, length, color, and wire gauge for higher-power applications.

Server and data-center GPU power harness for AI, rendering, or high-load computing systems
Replacement power connector cable for upgraded GPUs requiring 6+2 pin PCIe power connector interfaces
Custom cable sets for modded cases, small-form-factor builds and high-end e-sports systems
OEM harness for system integrators, industrial PCs and embedded computing platforms that need reliable PCIe power transmission
Precautions
Verify that the connector pin layout and PSU modular interface are compatible before installation; do not mix cables between different PSU brands without confirmation.
Do not exceed the rated current and power of the wire gauge and connector; use thicker wire for high-power GPUs as required.
Ensure connectors are fully inserted until they lock; loose terminals can cause overheating or intermittent power loss.
Avoid sharp bends or repeated flexing near the connector ends to protect terminals and insulation.
Keep the cable away from sharp metal edges and high-temperature components inside the chassis.
