A 4-pin Molex power cable that matches the hard drive/CD-ROM power connectors found on AT and ATX power supplies. Use it to tap into 5V or 12V DC from a desktop power supply for your projects — a convenient source of regulated power for high-current applications like LED strips, motors, and displays.
The cable comes with a pass-through connector on the other end (it's an adapter cable). Simply cut off the second connector before use to access the individual wires.
Key Features
- 4-Pin Molex Connector – Standard IDE/Molex power connector compatible with AT/ATX supplies
- 5V and 12V Access – Tap into both voltage rails from a single cable
- Pass-Through Design – Second connector can be cut off for direct wire access
Ideal For
- Powering electronics projects from an ATX supply
- LED lighting and display projects
- Bench power supply setups
- High-current 5V or 12V applications
Package Contents
- 1× 4-Pin Molex Power Cable (adapter style)
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- IDE
- Short for Integrated Development Environment, a program used to write, run and manage code. It matters because some learners prefer a traditional coding workspace instead of a guided notebook-style lesson.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
