0.3M 16AWG PCIE 5.0 12VHPWR 16Pin GPU Power Extension Cable, 12+4 Pin Male to Dual 8Pin PCIe Female Sleeved Splitter Cord, Compatible with NVIDIA RTX 40 RTX 50 Series High Power Graphics Cards

This PCIe 5.0 12VHPWR GPU power splitter cable is professionally customized for NVIDIA RTX 40 and RTX 50 series graphics cards that adopt the new 16Pin (12+4) 12VHPWR high-power interface. It converts the new 12VHPWR male plug into two conventional 8Pin PCIe female power ports, allowing users to directly draw stable power from the modular power supplys dual 8Pin GPU output terminals without purchasing a brand-new PCIe 5.0 power supply.

Constructed with upgraded 16AWG large-diameter oxygen-free copper conductors inside, the cable effectively lowers current resistance, minimizes voltage loss and temperature rise during GPU peak power output, greatly eliminating risks of wire softening, connector melting and thermal overload which often happen on thinner gauge cables when running heavy gaming, 3D rendering and AI computing tasks.

The entire wire harness is wrapped with tightly woven protective sleeving, which shields internal wires from friction damage caused by chassis fans and metal edges, prevents messy tangled wiring inside the case, and optimizes internal air circulation for better overall heat dissipation of the PC build. The total length is only 0.3 meters (0.98 feet), a reasonable short size that neatly routes power lines along the motherboard backplate, reduces cable clutter and does not obstruct the airflow path of CPU cooler, GPU heatsink and system case fans.

Each terminal adopts high-precision gold-plated contacts to enhance electrical conductivity, resist oxidation and corrosion from long-term use, and maintain firm plugging connection to prevent poor contact and intermittent power supply issues during intense GPU workloads. Strictly compliant with PCIe 5.0 12VHPWR official electrical specifications, it safely bears the high power demand of flagship RTX 40 and RTX 50 graphics cards.

It is an essential upgrade accessory for PC DIY builders, overclocking enthusiasts and workstation assemblers, solving the compatibility gap between older modular power supplies and the latest generation high-end NVIDIA graphics cards with safe and reliable power transmission performance.
