The connectors used to connect the product:
- 1 USB connector for motherboard to use memory card readers and 4 taken USB2
- 1 connector for usb3 mother carté to use two USB3 ports
- 1 SATA connector for eSATA connector
- 1 MOLEX connector (from the PC power supply) to power the product
Personally I do not use the usb3 nor sata and the product works perfectly for memory cards.
