The latest PCIe 5.0 cable is applicable to the GPU RTX4090 RTX4080 series.
When the 8P female connector is connected to the power supply, the solid pin holder is used to replace the terminal wiring commonly used in the market, which can support higher load, thus ensuring the stability of the graphics card branch.
It is made of high-quality materials, heat-resistant, non-aging, and very durable.
Small and light, no space, long service life.

Key Features

• 🔹 POWER YOUR RTX 50/40 SERIES GPU – 600W 12VHPWR OUTPUT This 4X 8 Pin to 12VHPWR 16 Pin (12+4) Mini power cable converts four 8-pin PCIe outputs from your compatible PSU into a single 16-pin 12VHPWR connector. Delivers up to 600W of power to NVIDIA RTX 5090, 5080, 4090, 4080, 4070, and 3090 Ti graphics cards. Ideal for high-performance gaming and workstation builds that need a short, high-power GPU cable without extra adapters.
• 🔹 10CM ULTRA-SHORT LENGTH – PERFECT FOR ITX & COMPACT BUILDS At only 10cm (3.9in), this short 12VHPWR cable minimizes clutter, reduces unnecessary bending, and improves airflow in compact cases, ITX builds, and vertical GPU mounts. The short length also helps avoid excess cable loops behind the GPU.
• ⚠️ Because the cable is only 10cm, plan your route before installation. Do NOT bend the cable within 3.5cm (1.4in) of the 16-pin connector.
• 🔹 16AWG PURE COPPER – SAFE & RELIABLE 600W DELIVERY Built with 16AWG pure copper wire for efficient power delivery up to 600W. Pure copper offers lower resistance than CCA or CCS alternatives, helping maintain stable voltage and reduce heat buildup. High-density single-sleeved design provides durability and clean cable management. 16AWG is the recommended gauge for 600W 12VHPWR applications under Intel ATX12VO and Cybenetics guidelines.
• 🔹 COMPATIBILITY – PSU NEEDS 4X 8-PIN, GPU NEEDS 12VHPWR Designed for PSUs with at least four available 8-pin PCIe/CPU ports. Use four separate PCIe cables from your PSU — do NOT use splitters or daisy-chains. Compatible with NVIDIA RTX 5090, 5080, 4090, 4080, 4070Ti, 4070, and 3090 Ti GPUs with a 12VHPWR (12+4) port.
• ⚠️ NOT compatible with PSUs that only have 6-pin PCIe connectors, non-modular PSUs without 4x 8-pin ports, or cross-brand modular PSU cables without pinout verification. Verify your PSU port count and type before ordering.
• 🔹 PLUG & PLAY – KIT INCLUDES & 2-YEAR 1x 4X 8 Pin to 12VHPWR 16 Pin (12+4) Mini Cable (10cm, 16AWG). Backed by a 2-year against manufacturing defects.
• ⚠️ CRITICAL SAFETY: Fully insert the 16-pin connector until you hear a distinct “click.” There should be no visible gap between the connector and the GPU socket. Do NOT use with additional adapter cables. Do NOT bend within 3.5cm (1.4in) of the 16-pin connector. Ensure good airflow around the cable. Not for mining use. If you notice discoloration, melting, or a burning smell, immediately disconnect power and inspect the cable and connector.
