PCIe Power Extension Cable Jonsbo DY-2 GPU 12+4-Pin for GPU power delivery

Jonsbo DY-2 is a PCIe power extension cable designed for GPU power delivery with a 12+4-pin connector configuration. The cable provides an extended, flexible connection between a compatible power supply output and a graphics card that requires a combined 12+4-pin input, allowing for cleaner cable routing and accommodation of different case layouts. It is intended to maintain stable power delivery for GPUs when a direct cable reach from the power supply is insufficient.

Advantages

The extension cable supports a 12+4-pin connector configuration used by certain modern graphics cards, offering a secure mechanical and electrical connection. Its construction reduces strain on connectors by extending reach and improving cable management within PC cases. The cable is compatible with systems that require a specific combined connector arrangement and is intended to preserve the original power path without modifying power supply outputs.

Suitable for (tasks / use cases)

• Extending reach from power supply to GPU in desktop PC builds
• Improving cable routing and airflow by enabling alternative cable paths
• Upgrading or retrofitting systems where the PSU cable length is insufficient

Key specifications

• Connector configuration: 12+4-pin for GPU power input
• Function: PCIe power extension for graphics cards
• Compatibility: designed for GPUs requiring a combined 12+4-pin connector
• Form factor: external cable extension for internal PC use

How to use

Insert the cable’s power input end into the matching power supply output or existing PCIe power lead, then connect the 12+4-pin output end to the graphics card’s power inlet. Ensure connectors are fully seated and latched where applicable. Route the cable to avoid sharp bends, pinching, or contact with moving parts such as fans. After connection, verify system power-on and monitor for stable operation according to your system’s normal startup procedures.

Recommendations

Use the extension only with compatible power supplies and graphics cards that require the specified 12+4-pin configuration. Avoid excessive bending or pulling of the cable and do not alter or splice the cable. If you experience power instability or connector looseness, disconnect and inspect connectors and, if necessary, consult the PSU or GPU manufacturer guidance.
