Understanding the Molex 4 Pin Plug
Before I dive into the buying tips, let me explain what a Molex 4 Pin Plug is. This connector typically consists of four pins that provide power to various components, including hard drives, fans, and other peripherals. I found it particularly useful in older power supplies, where it was commonly used to connect devices.
