## Description

Extend your LP4 power connections by up to 12 inches - The LP4POWEXT12 Extension Cable features two 4-pin Molex power connectors, one male and one female, and offers 12-inches in cable length, enabling you to extend your LP4 power connections and allowing you to position your devices (i.e. hard drive, DVD-ROM drive, add-in card, etc.) as needed within the system case. Constructed of only top quality materials and designed for optimum performance and reliability, this 12in internal LP4 power extender is backed by StarTech.com's lifetime warranty.

Review: Works as expected - I made a custom laptop stand using computer case fans with molex connections and needed a "sacrificial" molex cable to cut up and splice onto an on/off switch. Since I'm only powering case fans, it only needed two of the four wires, so I pulled out the two I didn't need (which is why there are only two wires in the my attached pictures), and soldered it all up. My previous molex cable was loose so the male end would just fall out if you breathed on it. The female end of this molex cable holds onto the male connector properly. I mean, there's not much to say - it's a molex cable and it delivers power.
Review: Good, but - Good for what it is but pretty low quality.
