I have a gigabite gtx970 that works great in my mining rig. but i just bought a used zotac gtx 970 and when i try to plug it all in i get this error:
"Please power down and connect PCIe Power Cables For This Graphics Card"

The problem is that the person i bought the zotac from didn't provide me with the original psu cord for the zotac. and since my gigabit gtx 970 is connected directly into the psu and the psu only has two PCI-e 6+2 cords (both of which are being used by my gigabite), i don't know what cord i need to connect the zotac to the psu. the zotac has 12 pin pci-e.

I also only have three 4-pin molex available on the psu, and I seem to need four 4-pin molex

any help would be much appreciated as I'm new to all this
 


It's a Corsair 550 and was on the cheaper side, so it definitely wasn't made for the job... any psu suggestions that aren't too pricey?
