I have a NVIDIA Geforce 7800 GTX (pretty old but still works good) It is on low power mode because my dell inspiron only supports SATA cables and the cables to put the graphics card on Full power uses a 2x 4-pin to 6-pin and i was wondering if there are any cables out there that can convert 2x 4-pin to 6-pin (http://www.newegg.com/Product/Product.aspx?Item=N82E16812267004) to SATA ?
