EZDIY-FAB 16pin (12+4) 12VHPWR PCIe 5.0 GPU Power Extension Cable — All White, 16AWG, Cable Combs, RTX 50/40 Series Compatible

Overview

Meet the EZDIY-FAB 16pin (12+4) 12VHPWR PCIe 5.0 GPU Power Sleeved Cable Extension. It is crafted to bridge your power supply to modern GPUs with a clean, reliable connection. Built for PCIe 5.0 graphics cards, it is compatible with RTX 3090 Ti, 4090, 4080, and other RTX 40-series models, while noting that some RTX 50-series configurations may not be recommended. This extension is designed as an upgrade that emphasizes both performance and aesthetics.

Designed with a focus on power delivery and visual appeal, the extension uses 16AWG tinned copper conductors and alloy copper terminals. It supports a maximum output of 600W, helping maintain stable operation during demanding tasks and reducing the risk of glitches under peak loads. The all-white sleeved exterior adds a refined look that blends well with lighter builds or coordinated color themes.

Why it stands out

• Dedicated 12VHPWR to 4x 8-pin configuration simplifies a complex wiring setup for compatible GPUs.
• Four integrated cable combs help keep cables aligned, creating a tidy, professional appearance inside your case.
• The 16AWG tinned copper design and sturdy terminals aim to deliver dependable power while minimizing resistance and heat buildup.
• Visible safety and aesthetics improvements are a result of the streamlined 1-to-4 pin arrangement, reducing clutter and potential miswiring.
• Not compatible with 12-pin GeForce RTX 30-series GPUs; supports RTX 3090 Ti, 4090, 4080, and other RTX 40-series GPUs.

Usage, safety, and installation tips

• Extension cable only: do not plug directly into the PSU. Use a power supply with sufficient power as recommended by the manufacturer (1000W+ is commonly advised for top-tier GPUs).
• Ensure you connect via a compatible PSU cable or the original 1-to-4 power adapter to maintain stable performance.

Specifications and care

This EZDIY-FAB extension is built to support power-hungry GPUs while maintaining a clean, minimalist aesthetic. It complements builds where cable management matters as much as performance, helping to reduce visual clutter and support airflow through thoughtful routing. For best results, pair with a capable PSU and follow the manufacturer’s installation guidance to verify compatibility with your specific GPU model.
