## Overview

The CRJ Electronics 4-Pin Molex to 5V Female USB Sleeved Adapter Cable converts your desktop ATX power supply's Molex connector into a stable 5V USB power source.

## Description

Power any USB 5V device using your ATX power supply

Review: As can be seen from my photo, but not on the product page, the wire sleeve to the molex plug isn't attached to the plug in any way to protect the wires from being pulled out or broken, it's just two thin wires running into the back of the plug.
Review: Works great, used it inside my gaming PC to power a small display via USB a to micro usb for monitoring my system temps. It installed easily and posted properly first time with no issues so far. The display gets the proper amount of power from this with no fluctuations. I've used two similar molex to USB connectors to power led light strips too, so its compatible with my power supply and will work reliability. The other two have several years of use on them already and have proven their durability. I trust this one has a long life ahead too. These are a good value, especially if you're still working with a non-modular PSU and have no other use for the molex connectors.

## Questions & Answers

**Q: If i go 12v into the molex will the usb come out at standard 5v?**
A: No. The 5v line in the Molex connector is wired directly to the 5v line in the USB connector. The 12v line isn’t connected to anything.

**Q: What gauge wiring does this use?**
A: Not sure. It's thinner than the power supply wires that plug into it. But gauge doesn't really need to be that thick on a 5v line as long as your amperage isn't too heavy. I'm using it for a 2amp LED light and it works fine for it.

*by T***C on 1 June 2020*

It works, perfect for my case LED strip that need just power from USB, it was cheap. The pins in the molex end of the adapter are a bit cheap and as such you need to really be careful and fiddle with it to align the male to the female molex power connection. Once its in, its all good.
