I have an old dell presicion 470 (I am currently ordering parts for a new pc) and Myfreind gave me his Asus R9 280x gpu. I have already made sure that the wattage is high enough in my psu (550 w) but my psu only has a 6 pin connector, the gpu requires 6 and 8 pin. would this adapter solve my problem? http://www.newegg.com/Product/Product.aspx?Item=N82E16812201038&nm_mc=KNC-GoogleAdwords-PC&cm_mmc=KNC-GoogleAdwords-PC-_-pla-_-Internal+Power+Cables-_-N82E16812201038&gclid=CjwKEAjw5ZKiBRDhqa-Yjcml9kYSJABia-RnCSVSNCg83y1mjfIyxClFZLjM3G6YEKfDUCxYdvDW0RoCllbw_wcB
