PSU 8 Pin 12V connector

Hi all,

I'm building up a new computer and I purchased a Thermaltake Element G with a TR2 RX-850 AP power supply included.

Here is my Motherboard, ASUS P6X58D-E:

So after I get everything installed I look to start plugging in some power. Coming out of the PSU is both a 24 pin power connector and a 8 pin PCI Express connector. My mobo manual says that there is both a EATX12V and EATXPWR plug. Now the 24 pin I have, but what I don't have is the 8 pin 12V connector. I see a spot to attach this to my PSU and then presumably to the motherboard, but I do not have this cable with the included PSU cables. Is this a cable that I need in order to power up the mobo? Any thoughts/advice on this would be appreciated while I continue to scourge my supplies to see if I have something. Thank you.

PCI-E power connectors are six-pin, not eight-pin.
Edit: This is incorrect. The PCI-E 2.0 spec includes an option for an eight-pin power connector for higher-power video cards.

Eight-pin connectors on motherboards and power supplies are alternatives to the older four-pin ATX12V power connectors.

It looks like you have a four-pin ATX12V power connector on your motherboard. This should match a four-pin cable on your power supply. Either a four-pin or eight-pin power connection should be made, along with the entire 24-pin ATX power supply connector if available on your motherboard and power supply.

Hello.

Thanks for the reply. After finally getting a hold of someone at Thermaltake, they informed me that I should have the 8 pin to 8 pin male to male EPS connector included. Unfortunately this was not the case and they said they would send me a new one.

In the meantime, I ran over to Fry's and picked up some extender cables (male to female) and split and sodered them to get something that worked. Motherboard fired right into POST and looks to be working now. Again thank you for the help.
 
Whoops.

I forgot about the EPS standard. I've never seen it used, so it's pretty easy for me to forget about it. Sorry if I caused you any problems with my statement about PCI-E power connectors.
