Model Number:
12+4PIN Extension Cable for RTX3090L =700MM
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.
