I need another power cable to run from my psu to one of the cards. I have a Corsair TX750M PSU. Where can I find http://www.corsair.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/h/x/hx-txm_cable_pci-e_k.png <that cable for sale. I've been looking online for a while and have yet to see it anywhere except Corsair's Modular Cable packages which retail at $80. I only need the one cord.
