The Molex 4-pin peripheral power connector pinout is a commonly used cable for connecting peripheral devices to a computer power supply. This type of cable is used to power devices such as hard disk drives, CD/DVD drives, and fans.

The pinout for the Molex 4-pin peripheral power connector is as follows:

1. +5V – This pin supplies power to the device being connected.

2. GND – This pin is the ground connection for the device being connected.

3. GND – This pin is an additional ground connection and is used to provide additional grounding for the device.

4. +12V – This pin supplies power to the device being connected.

It is important to note that in some cases the +12V and +5V pinouts may be reversed, so it is important to check the documentation for the device being connected to ensure proper connection.

The Molex 4-pin peripheral power connector is designed to handle a maximum current of 11 amps and a maximum voltage of 12 volts. It is important to use caution when connecting devices to prevent damage to the device and the power supply.

In conclusion, the Molex 4-pin peripheral power connector pinout is a commonly used cable for connecting peripheral devices to a computer power supply. Understanding the pinout and proper use of this cable is important for ensuring safe and efficient operation of devices connected to a computer power supply.
