Description: This is a right-angle, 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 the datasheet below for pin spacing dimensions.

  • Does anyone know a suitable mouser or digikey part number for this?

    • Really wish SFE would spill the beans lol I need a bulk order soon and they are below what I need already. I know it’s a Molex Mini-Fit Jr. but where can they get them so cheap? Mouser and Digikey both are over $3 a piece at quantity. Something tells me they won’t be in a hurry to restock this particular part either.

      • Depending on how big of a bulk order you need, contact customerservice@sparkfun.com. They can help with custom large orders so that you can get your order in a timely fashion and it doesn’t totally kill our stock flow.

  • The pins in this connector are really tight in the power supply’s connector. I mean it takes a lot of force to plug or unplug it. At first I was a little concerned that the tab for the clip wasn’t double-wide to facilitate clipping to a in a 20-pin power supply, but with it being this tight, the clip is unnecessary. But really, it being this tight makes it pretty unusable.

  • This connector fits on the atx breakout board, unlike it’s straight counterpart.
