2Pin Cable Molex Connector to C7 Female Plug 18AWG Extension Cord for Computer
1. Product Decription
2Pin Molex to C7 Cable is a power adapter cable used to connect devices with 2-pin Molex interface to C7 ("eight-shaped" power socket).
- Molex end: usually a 2-pin plug, used to connect motherboards, power modules or other electronic devices.
- C7 end: standard AC power interface (non-polarity), commonly used for low-power devices (such as laptop power supplies, monitors, speakers, etc.).
2. Advantages
Flexible power supply: can convert low-voltage DC (such as 12V/5V) into AC power supply, suitable for a variety of devices.
Wide compatibility: C7 interface is highly versatile and adaptable to a variety of household appliances and electronic devices.
Space saving: lighter than traditional power adapters, suitable for compact devices.
Low-cost solution: no need to purchase a dedicated power adapter separately.

5. Purchase advice
Confirm interface matching: Check the pin pitch of the Molex terminal (such as 2.54mm) and the size of the C7 plug.
Power requirement: Make sure the cable supports the power of the target device (usually ≤250W).
Wire quality: Choose copper core wire and shielded style to improve safety.
6. Precautions for safe use
Do not overload: Avoid connecting devices that exceed the rated power to prevent overheating or short circuit.
Check polarity: Some Molex interfaces have anti-reverse plug-in design, and the positive and negative poles need to be confirmed.
Avoid humid environment: The C7 interface is not waterproof and needs to be used in a dry environment
Regular inspection: If the wire is found to be aging or the interface is loose, it should be replaced immediately.
7. Frequently Asked Questions (FAQ)
Q1: Can this cable be used to power a laptop?
A1: It is only feasible when the laptop power adapter uses a C7 interface, but the voltage matching needs to be confirmed.
Q2: Does the 2-pin Molex end support high current?
A2: It depends on the wire diameter and terminal material. It is generally recommended for ≤10A current.
Q3: Can I replace the C8 (with ground wire) interface by myself?
A3: Yes, but you need to make sure that the ground wire is connected correctly, otherwise it may cause safety hazards.
