PSU Question

[craigap]

I will putting together a computer for the first time. My build will utilize the PCI x16 for the Video card, PCI x1 for a TV Tuner, and the PCI x4 for another Tv tuner. I looked at a bunch of PSU's and I don't see any that have more than two PCI express Power Connectors. http://www.newegg.com/Product/Produc...82E16817104014
This is the link to the PSU that I was originally going to purchase.
I did notice that the Video card that I have chosen includes a hard drive power dongle to PCI-E 6 pin adapter. Will this allow me to use one of the HDD power connectors on the PSU to power the Video card and then leave the other two 6 pin PCI express connectors for my two TV tuners. If so, will I still have enough HDD connectors available for My two HDD's and a possible third down the road.
My biggest worry is getting a PSU that won't have all the connections for the components I am putting into my build.

The tuner cards do not have external power jacks, you only need one PCI-E power connector. If you run out of 4 pin Molex connectors, you can get Y-splitters.
