i recently added a new power supply and video card , gatway dx-4860 , everything works with the exception on second drive , in past i did have drive d , using sata . now i have only molex . i tried molex to sata ,and can not get drive to show . i tested output voltage from molex yes 5v and 11.86 just under 12v from yellow to black .connected to mobo and can not see drive ,drive is 2t western digital .so i am puzzled . is this slight under voltage issue .should read 12v but so slightly under . or am i over looking something .
