Need help re power supply cables

I am planning to install a USB 3.0 PCI express card in my desktop that requires a 4 pin female power supply connector. See picture below

The only spare connectors from the Dell XPS 9000 power supply connectors are 2 six pin connectors and 1 two pin connector. (all female)

Do all the cables coming from the power supply furnish the same voltage?
Is there any adapter that would convert one of the existing spares to the 4 pin male connector on the PCIe card??

​

 

Did you check to see if the USB 3.0 Card came with its own cable ?

 

thanks for your reply..it doesnt ...do you know of a possible adapter that might work with the existing spare cable in the photo??

 

The card has a Parallel ATA hard drive connector. What type of hard drive do you have? There's probably some type of splitter available from the local shop to either adapt SATA to PATA or to split the PATA already supplying a drive into two.
