8 pin EATX motherboard

I have just purchased an Asus motherboard and an i7-2600 cpu. The mobo has the 8 pin EATX connect and none of the power supplies I have has the correct connector (only the 4 pin). Is there an easy way to add this to an existing power supply? I'm not thinking about the 4 pin to 8 pin adapter since that does not meet the requirement for independent 12v supply although I imagine it will work. I've been looking around for information on this and haven't found much. I have yet to find an off the shelf power supply that has this connector, but I'm sure there must be one.

Thanks for your help
 

Ok, I finally found them. I guess I'll wait a few days to see if I can figure out how to mod an existing power supply and if nothing turns up I'll have to buy a new one.
 
Some PSUs have two 4pin EATX PSU--> Motherboard Connectors.
Post your exact PSU model and we might be able to help you out.
 
Here's a workaround for anyone happening to read this thread which I figured out subsequent to my initial posts. First, I happened to have a spare ATX power supply which no longer worked (it lost it's soft start capability, but seemed to work otherwise). It turns out the 4 pin connector will mate up with the 4 holes to the left of a 4 pin cpu connector. So it's a homemade 8 pin cpu connector. It helps to trim some of the plastic from the side adjacent to the exiting 4 pin connector. It turns out to be the side with "ears" on it. This just makes it fit without have to force it. I removed this from the old psu, leaving about 10" of wire. There are 4 wires(red, black, orange, and yellow)

Then, assuming you have an extra 4 pin molex connector hanging off the power supply you intend to use, cut that off making sure to leave enough wiire to be able to reach the 8 pin cpu connector on the mobo. You will only use 2 of the wires that went to the molex connector, a black ground wire and a yellow 12v wire. Connect the yellow wire that went to the molex to the red and black wires coming from the modified 4 pin connector. Connect the black molex wire to the orange and yellow wires. Before I hooked anything up I started the PSU unconnected to the mobo and checked to make sure that I had the correct voltages.

That's it. I plugged it in and it works.
