hi, i have an r9 270x and it requires a dual 6 pin power connector (my psu is zalman 600 HP the guy i bought it to didnt include the 8 to 6+2 modular cable). i have only 1, 6 pin so i used molex to 6 pin for the other. i have a full windowed case and molex to 6 pin looks awful. i really cant find a 6pin female to 6 pin female in my country. so if i may ask is it safe to extend molex to 6pin using a 6 pin extension cable
