Product Description
This 4Pin power cable connector adapter is designed to convert or extend a standard 4Pin Mini-Fit style power output between a power supply unit and a motherboard, PCB header or server module. Two yellow and two black wires clearly separate power and ground lines, supporting stable 12 V power transmission for CPU or other electronic loads.
Each circuit uses stranded oxygen-free copper conductors with robust PVC insulation and crimped terminals, ensuring reliable contact and low loss under continuous current. Compact 2×2 housings with latch structures provide a secure mating interface on both the male and female sides, preventing accidental disconnection during installation or vibration.
The short adapter length is ideal for tight chassis layouts, while OEM/ODM customization (wire gauge, length, color, terminal plating, and connector type) can meet special requirements in PC, server, telecom or automotive low-voltage harness applications.

Applications
Adapting PSU 4Pin output to CPU or auxiliary motherboard power connector
Extending short 4Pin headers on PCB, fan hub, or driver boards
Power wiring for small servers, network equipment and industrial controllers
Low-voltage electronic devices and LED drivers using 4Pin Mini-Fit style interfaces
Custom test fixtures and lab setups requiring quick 4Pin power routing
Precautions
Always confirm pin assignment (power and ground positions) on both mating connectors before use; reverse wiring can damage components.
Do not exceed the specified current per pin; select heavier wire gauge for higher loads if needed.
Avoid excessive bending or pulling near the housings to protect crimped terminals and insulation.
Keep the cable away from sharp metal edges and high-temperature parts inside the chassis.
Custom versions for mixed signal and power, different pitch or multi-branch cable assemblies are available for larger orders.
