ATX Power Supply Connector - Straight

This is a 24-pin Molex Mini-Fit Jr.? connector, commonly used as the power supply connector on ATX motherboards. Two rows of twelve pins are broken out two rows of through-hole male headers. See datasheet for the pin spacings and other dimensions.

Pair this connector with a standard computer power supply and you can source a number of different voltages (+3.3V, +5V, +12V, -12V, -5V) to your project.

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

  • Does anyone have an eagle file for this connector?

  • I have created a component file for this part in easyeda. When I get my boards I ordered using this component and it's a good test fit, I will share.

    • here is the link to the gerber file as mentioned above.

  • This needs an eagle file.

  • warning: this is not compatible with https://www.sparkfun.com/products/9558 - Sparkfun did not claim they were compatible, do not make the same assumption as me. You can snap off the plastic tabs at the end though, and it will fit.

  • Do you have a 20 pin version of this connector?

  • Is this part available in the Eagle library?

    • Doesn't look like it. SparkFun-Connectors.lbr only has the right-angle one. Should be able to modify that Device to add the regular Package, though - all the required information is in the dimensional drawing datasheet.

  • At what scale should I print (on to A4) the Dimensional Drawing to get the hole layout 1:1?

  • I purchased this connector with the breakout board only to realize that the white pegs on the ends of the connector, do have corresponding holes on the board. Now I know.
