0.3M 16AWG PCIe 5.0 12VHPWR 16Pin GPU Power Extension Cable, 12+4 Pin Male to Dual 8Pin PCIe Female Sleeved Splitter Cord for RTX 40 RTX 50 Series High Power Gaming Graphics Cards Chassis Modding

This PCIe 5.0 12VHPWR GPU power splitter cable is professionally customized for NVIDIA RTX 40 series and RTX 50 series high-power gaming graphics cards that adopt the new 12+4 Pin 12VHPWR power interface. It converts two standard PCIe 8Pin power outputs from your modular power supply into one official 16Pin 12VHPWR male plug, providing stable and sufficient power input for power-hungry flagship GPUs, effectively solving the shortage of native 12VHPWR cables on older power supplies.

Constructed with heavy-duty 16AWG oxygen-free copper internal conductors, the wire gauge is thick enough to carry the high continuous current required by top-tier graphics cards. It minimizes line loss, voltage drop and heat buildup during extreme full-load operation, greatly lowering the hidden danger of connector overheating, scorching and melting that frequently occurs with thin-gauge inferior cables.

The entire cable is wrapped in dense black braided sleeve, which not only upgrades the visual aesthetics of your PC chassis modding build, but also protects inner wires from abrasion, extrusion and heat aging caused by proximity to CPU coolers and GPU heat sinks. The 0.3-meter (0.98 feet) short length perfectly fits compact mid-tower and small ITX cases, eliminating redundant loose cables that block internal airflow and degrade overall thermal performance.

The 12VHPWR 16Pin male terminal features a secure locking buckle mechanism. Once fully inserted into the graphics card power port, it stays firmly fastened even under chassis vibration and high temperature, preventing partial contact resistance and fire hazards triggered by half-plugged connectors. Each 8Pin female end adopts precision crimped gold-plated terminals to ensure zero intermittent power cut during long-term 24/7 gaming and rendering workloads.

It supports full PCIe 5.0 power specification and all power delivery protocols for RTX 4090, 4080, 5090, 5080 and other high TDP Ada Lovelace & Blackwell architecture GPUs. Please note to connect both 8Pin ends to separate independent PSU PCIe power rails instead of using another splitter chain, to guarantee safe and reliable heavy-load power delivery for your expensive graphics hardware.
