Hello. So i had to raplace my cs750m PSU and i got my self a EVGA 650BQ. but the problems start when i want to plug in my vga cables ant there are only 6+(6+2)=14pins but my sapphire r9 390 has 16 prots. so i was wondering if can take cable for my old corsair PSU and use it? or i need some special EVGA cable? i don't have much time to order new cables so i was wondering if i can just use the old cable they have 16pins.. i think if GPU has 16 then i have to fill all the lsots ?
