Internal Molex Cables: Powering Your Computer's Internal Components

Introduction

Internal Molex cables, also known as internal power cables or Molex power cables, are an essential component in modern computer systems. These cables are designed to provide power to various internal devices, such as CD/DVD drives, floppy disk drives, hard drives, and other peripherals. With a wide range of connectors and cable types, CableLeader offers a comprehensive selection of internal Molex cables to meet your specific power connectivity needs.

Molex Connectors: The Power Behind Your Components

Molex connectors are the backbone of internal Molex cables, providing a secure and reliable connection for power delivery. These connectors come in various shapes and sizes, each designed for a specific purpose. Some of the most common Molex connectors found in internal Molex cables include:

  • 5.25" Male (LP4): This connector is typically used to connect to the power supply unit (PSU) and serves as the primary source of power for internal devices.
  • 5.25" Female (LP4): Compatible with the 5.25" male connector, this female connector is commonly found on CD/DVD drives and other internal devices that require power.
  • 3.5" Female: Smaller in size, this connector is designed to provide power to floppy disk drives and other compact internal devices.
  • SATA 15-Pin Female: Allowing for seamless integration with modern storage solutions, this connector enables SATA hard drives to be powered from a standard LP4 connection.

Versatile Cable Configurations

CableLeader's extensive range of internal Molex cables offers a variety of cable configurations to cater to different power distribution needs. These include:

  • Y Cables: Splitting a single input into multiple outputs, Y cables allow you to power multiple devices from a single source.
  • Extension Cables: Designed to extend the reach of your existing power cables, extension cables provide the necessary length to connect devices in hard-to-reach areas.
  • Adapter Cables: Bridging the gap between different connector types, adapter cables enable compatibility between various power sources and devices.

Quality and Reliability

At CableLeader, we understand the importance of quality and reliability when it comes to powering your computer's internal components. All of our internal Molex cables are crafted with high-quality materials and are RoHS compliant, ensuring durability and safety. Whether you're building a new system or upgrading an existing one, you can trust CableLeader to provide the power connectivity solutions you need.

Conclusion

Internal Molex cables play a crucial role in ensuring seamless power distribution within your computer system. With CableLeader's extensive selection of internal Molex cables, Y cables, extension cables, and adapter cables, you can rest assured that your internal components will receive the power they need for optimal performance and longevity.

What is a Molex cable used for?

Molex cables are primarily used for providing power to various components inside a computer, such as the motherboard, fans, floppy disk drives, CD/DVD drives, video cards, and some older hard drive models. The 4-pin Molex connector is a standard power connector for these internal devices.

Are Molex cables necessary?

Molex connectors are necessary when you don't have any available 3-pin or 4-pin headers left on your motherboard to connect fans. In such cases, you can use Molex connectors to power the fans directly from the power supply unit (PSU) instead of the motherboard.

What are the disadvantages of Molex connectors?

Some disadvantages of Molex connectors include:

  • Limited Power Delivery: Molex connectors have limited power delivery capabilities compared to newer connectors like SATA and PCIe.
  • Inefficiency and Cable Clutter: Molex connectors can lead to cable clutter and inefficient cable management inside the computer case.

What is the difference between a Molex cable and a SATA cable?

Molex is a company that primarily manufactures electrical connectors, while SATA (Serial Advanced Technology Attachment) is a communication standard used for connecting hard drives and SSDs to the computer. SATA defines the cable connections and data communication timings between the computer and the storage devices.

What is the most common Molex connector?

One of the most popular Molex connectors is the right-angle wire-to-board 5569 series connector, which can provide up to 13A of power by accommodating 16 AWG wire at a 4.20mm pitch.

What is a 4-pin Molex cable?

The 4-pin Molex power supply connector is a standard connector used for powering various internal devices, such as PATA-based hard drives, high-end video cards, and some older optical drives.

How many amps can a Molex connector handle?

Molex offers a vast selection of power connectors with current ratings up to 200.0 A, catering to the diverse power needs of various markets.

What are Molex cables for PSU?

Molex cables are primarily used for power supply units (PSUs) or to connect PSUs to internal devices like hard drives. A common example is the Molex-to-SATA power cable used to provide power from the PSU to SATA drives.

How many watts can a 4-pin Molex handle?

While the Molex 4-pin connector itself is designed to handle up to 156 watts, the wire crimped to the connector cannot handle that much power. The 4-pin Molex connector typically has only one 12V wire, limiting its practical power delivery capability.

Where do I connect my Molex cable to my power supply?

To connect a Molex cable to your power supply unit (PSU), locate the male (protruding pins) and female (recessed holes) ends of the Molex connectors. The male end connects to the PSU, while the female end connects to the device you want to power, such as a fan or drive.
