PCIe 5.0 12VHPWR 16Pin (12+4Pin) to 4x8Pin PCI-E GPU Power Adapter Cable, Conversion Cord Compatible with RTX 3090Ti, RTX 4080, RTX 4090 High Power Gaming Graphics Cards

This PCIe 5.0 12VHPWR 16Pin to 4 x 8Pin GPU power adapter cable is engineered to bridge the compatibility gap between traditional ATX power supplies and modern high-end graphics cards equipped with the 12+4Pin 12VHPWR interface. Instead of investing in a brand-new PCIe 5.0 certified power supply, you can utilize your existing PSU with four available PCI-E 8Pin outputs to power RTX 3090Ti, RTX 4080 and RTX 4090 graphics cards efficiently.

The internal wiring adopts high-purity oxygen-free copper conductors, which deliver exceptional electrical conductivity, lower resistance, minimize voltage drop and restrain excessive heat generation during continuous high-load scenarios, including competitive gaming, 4K video rendering, 3D modeling and AI computation. Each connector features an integrated locking latch that fastens securely after insertion, eliminating poor contact or unexpected power shutdown triggered by chassis vibration, transportation or accidental cable pulling.

Precision molded cable ends add reinforced strain relief to protect internal wires from cracking and abrasion due to frequent bending. The orderly cable structure helps optimize airflow inside the computer case, improving overall thermal performance. No drivers or complicated setup procedures are required; just plug both ends into matching ports for instant use.

Important reminder: Please confirm your power supply provides enough rated wattage to sustain your graphics cards peak power consumption. Ensure all four 8Pin PCI-E connections are plugged into separate power rails of your PSU for optimal safety. This adapter is designed specifically for listed NVIDIA graphics models and may not work properly with other third-party 12VHPWR devices. Ideal for gaming PC builders, workstation upgrades, IT hardware maintenance and graphics card replacement projects.
