I used male and female for my extension
The Datasheets are in englisch. You need Molex Connectors from the Micro-Fit 3.0 System.
The Printer have a plug housing (male) and the cable from the AMS have a receptacle housings (female).
So you need a cable that have male an female because the ams-cable is firmly connected to the housing.
After a Quick comparison with my computer I can say for sure that a Standard ATX cable will not work
The blue one is a standard ATX-Cable and the black one is a the Micro-Fit 3.0 with is used for the ams cable. The standard-atx System is too big.
