JOYJOM 16Pin GPU Cable to 3x8 Pin PCIe Extension (Type A) Instruction Manual

1. Introduction

This instruction manual provides essential information for the proper installation, operation, and maintenance of your JOYJOM 16Pin GPU Cable to 3x8 Pin PCIe Extension (Type A). This cable is designed to provide stable power delivery to high-end graphics cards such as the RTX 3090 Ti, 4070 Ti, 4090, and 4080 series, which require a 16-pin 12VHPWR connector. Please read this manual thoroughly before use to ensure optimal performance and safety.

2. Safety Information

• Always ensure your power supply unit (PSU) has sufficient wattage and available 8-pin PCIe connectors to support your graphics card and this adapter. This extension cable requires three unoccupied 8-pin PCI-e ports on your power supply.
• Do not attempt to connect fewer than three 8-pin connectors to your power supply, as this will prevent proper function and may cause damage.
• Ensure all connections are firm and fully seated to prevent loose contacts, which can lead to overheating or system instability.
• Avoid excessive bending or straining of the cable, especially near the connectors, to prevent damage to the internal wires and insulation.
• Keep the cable away from sources of extreme heat or moisture.
• If you are unsure about any installation steps, consult a qualified technician.

4. Setup and Installation

Follow these steps to correctly install your GPU power extension cable:

1. Power Off System: Before beginning installation, ensure your computer is completely powered off and unplugged from the wall outlet.
2. Open PC Case: Carefully open your PC case to access the graphics card and power supply.
3. Identify GPU 16-Pin Connector: Locate the 16-pin 12VHPWR power connector on your graphics card.
4. Choose Correct Cable Type (Type A or Type B): The JOYJOM 16-pin cable comes in two orientations: Type A and Type B. It is crucial to select the correct type based on your GPU's 16-pin connector orientation to prevent cable strain and ensure proper fit.
   • Type A: The small 4-pin section of the 16-pin male connector is oriented towards the cable. This is typically used when the GPU's 16-pin connector is parallel to the cooler, or if the small 4-pin is on the GPU backplate side.
   • Type B: The small 12-pin section of the 16-pin male connector is oriented towards the cable. This is typically used when the GPU's 16-pin connector is deeply recessed, or if the small 4-pin is on the GPU cooler side.

5. Connect to GPU: Firmly plug the 16-pin connector of the JOYJOM extension cable into the corresponding port on your graphics card. Ensure it clicks into place and is fully seated.
6. Connect to PSU: Connect the three 8-pin PCIe connectors from the extension cable to three unoccupied 8-pin PCIe ports on your power supply unit. Each 8-pin connector must be used. Do not leave any unconnected.
7. Cable Management: Route the cable neatly within your PC case to avoid obstructing airflow or interfering with other components. The 90-degree right-angle design helps manage cables in tight spaces.
8. Close PC Case: Once all connections are secure, close your PC case.
9. Power On System: Plug your computer back into the wall outlet and power it on.

5. Operation

Once installed, the JOYJOM 16Pin GPU Cable operates passively, extending the power connection from your PSU to your GPU. Its primary function is to ensure stable and reliable power delivery to your high-performance graphics card. No user interaction is required beyond proper installation.

• The cable is designed to support up to 600W output, suitable for demanding graphics cards.
• The 16AWG tinned copper wire construction ensures efficient power transfer and durability.
• The 90-degree right-angle connector helps reduce cable bending stress and allows for cleaner cable management in compact PC cases.

6. Maintenance

The JOYJOM GPU power cable requires minimal maintenance. Follow these guidelines to ensure its longevity:

• Regular Inspection: Periodically check the cable and its connectors for any signs of wear, fraying, or damage. Ensure connections remain secure.
• Cleaning: If necessary, gently clean the cable with a dry, lint-free cloth. Do not use liquid cleaners or solvents. Ensure the system is powered off and unplugged before cleaning.
• Avoid Stress: Do not pull on the cable to disconnect it; always grasp the connector housing. Avoid sharp bends or kinks in the cable.
