Composite Out Cables/Dongle

[pigwalk]

Hey guys, I just ordered this card for my system with the intent on using the composite outs on my HDTV Link. However, I forgot that the open box products don't have the accessories, mainly the composite out cable/dongle, whatever it is. Where else can I order the cable from? I'd like to contact ASUS, but I need the product registration and serial number, which I won't have until the card gets here, but I'd like to order the cables next day so I can have them when the card gets here. Any ideas?
