This is an original Seasonic Modular Cable; therefore, it only works with Seasonic power supply.

It will not work with any other brands of power supply; therefore, please do not order it if your power supply is not a Seasonic power supply.

This cable works with most of Seasonic power supply manufactured after Dec. 2012. There are only two exceptions: X650 and X750.

For X650 and X750 models, if the manufactured date was before Dec 2012, it uses 16+10pin to 24pin mainboard connector cable.

For X650 and X750 models, if the manufactured date was after Dec 2012, it uses 18+10pin to 24pin mainboard connector cable.

If unsure, you always can contact us and we will be glad to verify for you.
