Product Description
This long PSU power connector cable is designed as an 8 pin male to 8 pin female wire harness for stable power delivery between modular power supplies and graphics cards, CPUs or other high-load devices. Stranded oxygen-free copper conductors and heat-resistant insulation minimize loss and temperature rise during high current operation. The full-length braided sleeving improves wear resistance, bundling and appearance for high-end gaming PCs, workstations and server chassis. Precision-molded connector housings with plated terminals ensure reliable mating, low contact resistance and long service life. Customization of length, wire gauge, pin assignment and connector style is available to match different PCB layouts or system designs.

Precautions
Confirm that connector keying, pin definition and gender match both PSU and device before use.
Do not exceed the specified current per pin or bundle the cable tightly around high heat sources.
Ensure each connector is fully inserted and latched to avoid intermittent contact or overheating.
Avoid repeated sharp bending or pulling on the cable; maintain an adequate bending radius.
For special environments such as automotive or 24/7 server operation, discuss detailed requirements and safety margins with the supplier to select the most suitable customized connector cable.
