Here's a photo of the cable:


The Molex connector was taken from a Molex-to-floppy drive adapter 
cable. The cable diameters seemed similar in size as the Hauppauge 
cable. I did use the full cable length from the wall wart.

I am going to experiment with using another supply line on the power 
supply. The power supply is only a 500W, hopefully that is not an issue.

Thanks for the feedback/thoughts.
