600W 12VHPWR Cable 3x8 Pin to 16 Pin (12+4) PCIe 5.0 GPU Power Adapter 16AWG 27.5 Inch (70cm) PSU Extension Cord for RTX 3090 Ti/4070 Ti/4080/4090, for ASUS EVGA Seasonic Triple 8 Pin Input

1. 600W POWER DELIVERY TRIPLE 8-PIN INPUT This PCIe 5.0 power cable features three standard 8-pin PCIe connectors on the PSU side, providing up to 600W of stable power (200W per connector theoretically) to meet the demanding power requirements of the latest high-end GPUs. Fully compliant with ATX 3.0 and PCIe 5.0 specifications, it delivers reliable power to NVIDIA RTX 30/40 series graphics cards.
2. 16AWG PREMIUM CONSTRUCTION HIGH THERMAL ENDURANCE Built with high-quality 16AWG tinned copper wire, capable of carrying up to 55A of current with 105°C temperature rating. The internal wire and connector terminals are rated to handle 600W continuous power delivery, ensuring safe and stable operation even under full load. Each cable is factory-tested for performance and safety.
3. UNIVERSAL COMPATIBLE WORKS WITH MAJOR PSU BRANDS This cable is designed to work with standard 8-pin PCIe outputs from modular power supplies. Compatible with: ASUS: ROG Thor/Strix, TUF Gaming, Prime series EVGA: G2, G3, G5, G6, P2, T2, etc. Seasonic: PRIME, FOCUS, CONNECT, Core series Other Brands: Most modular PSUs with standard 8-pin PCIe ports (Corsair, Thermaltake, Cooler Master) Note: The 12VHPWR/12V-2x6 port on different PSU models may have different pin definitions. This cable is for use with the 8-pin PCIe output portsNOT for plugging into the modular port on the PSU directly.
4. COMPATIBLE WITH RTX 40 & 30 SERIES GPUs The 12VHPWR (12+4) output works with all modern NVIDIA GPUs: RTX 40 Series: 4090, 4080, 4070 Ti, 4070 RTX 30 Series: 3090 Ti Fully supports both original 12VHPWR and the updated 12V-2x6 connector standards the cable is identical and backward compatible.
5. OPTIMAL 27.5-INCH (70CM) CABLE LENGTH Total length of 27.5 inches (70cm) provides ample reach for routing behind the motherboard tray or through cable management channels in full-tower and mid-tower cases. This length offers enough slack for flexible positioning while avoiding excessive cabling that clutters your build.
6. OPTIMAL 27.5-INCH (70CM) CABLE LENGTH Total length of 27.5 inches (70cm) provides ample reach for routing behind the motherboard tray or through cable management channels in full-tower and mid-tower cases. This length offers enough slack for flexible positioning while avoiding excessive cabling that clutters your build.
7. CRITICAL INSTALLATION SAFETY WARNINGS The #1 cause of 12VHPWR connector failure is incomplete insertion. When connecting to your GPU: Push the connector straight and firmly into the GPU port until you hear a CLICK Verify that no gap exists between the connector housing and GPU socket Do not bend the cable within 35mm (1.4 inches) of the connector maintain a straight approach as required by PCI-SIG specifications Regularly inspect the connector for signs of melting or discoloration, especially with high-power GPUs like RTX 4090.

Unlock the full potential of your NVIDIA GeForce RTX 40/30 Series graphics card with the 600W PCIe 5.0 3x8 Pin to 12VHPWR Cable. Unlike standard dual 8-pin cables that may not fully cover the 600W TDP of flagship cards, this cable utilizes three 8-pin PCIe inputs to ensure your GPU receives stable, ample power for peak performance.

Perfect for high-end builds, overclocking, or when you want to utilize all available ports on your modular PSU without daisy-chaining.

Feature Standard Dual 8-Pin Cable Our Triple 8-Pin Cable

Input Connectors 2x 8-pin (300W+300W theoretical) 3x 8-pin (200W per connector)

Total Power Capability Up to 450W safely Up to 600W safely

Margin for RTX 4090 Limited (only ~50W overhead) Ample overhead (150W+ margin)

Ideal For Mid-range GPUs (4070 Ti, 4080) Flagship GPUs (4090, 3090 Ti, OC models)

The triple 8-pin design distributes the power load across three separate PSU ports, reducing the risk of overloading a single cable and ensuring your high-end GPU gets consistent power without voltage droop.
