Product Description

Product Description

This PCI-E 8Pin to 6+2Pin power cable connector is designed for stable power transmission between modular power supply units and graphics cards or servers. The assembly uses oxygen-free copper wire and precision-formed power terminals to reduce loss and heat buildup during operation. Each wire is individually sleeved and then covered with a braided nylon outer jacket, delivering a clean look for custom gaming PCs while protecting the cable from abrasion and bending fatigue.

Both the male and female connector housings feature secure latching structures to prevent accidental unplugging from the PCB or power socket. Flexible customization is available for pin assignment, cable length, pitch-compatible housing, color, and labeling, allowing integration into OEM systems, server racks, or automotive-grade electronic modules.

Applications 

Server and data-center power cable connector between modular PSU and backplane

Telecom base station and network cabinet power distribution harness

Industrial automation control panels and PLC power input wiring

Automotive and new energy storage battery packs for low-voltage auxiliary power

Custom PCB power connector link for test equipment and electronic instruments

Precautions 

Verify pin assignment and connector type on both PSU and equipment before installation to avoid reverse connection or short circuit.

Do not exceed the rated current per wire; select appropriate wire gauge according to actual load.

Route the cable away from sharp edges, moving parts, or high-temperature components to protect the jacket and insulation.

Secure the harness with cable ties or clips inside the cabinet to reduce strain on the terminals and maintain stable connections.

Custom designs for special signal and power mixed wiring, different pitches, and multi-branch cable assemblies are available for batch orders.
