Is it a standard 4-pin molex connector like the one on the V5's? Or is it one of those 3 or 4 pin to 4-pin molex connectors that connect HSF's to motherboards or video cards? A molex connector is the type you see coming out of your PSU and connecting to IDE peripherals like HDD's and CD/DVD drives.
In any case, you can pick up every possible type of these connectors (Male/Male, Female/Male, Female/Female, Y-Adapter M/F, etc. etc. you get the idea) at your local Radio Shack
Just bring your card in or take a visual picture of what the connector is supposed to look like so you know what to buy, otherwise you'll have a bunch of plastic baggies with different types of connectors like me

Edit: Yep its just a floppy connector. If your PSU has an extra floppy connector (most 400W and above have 2 or more), just plug it into the card. If not, go to Radio Shack and pick up a Y-splitter from Molex (big head, 6 sided, 4 pin) male ------> 1 molex female and 1 4-pin floppy female. If you have a spare molex connector from your PSU, you can just pick up a molex male to floppy female.
