'm trying to upgrade my graphics card but my psu only has 2 spare female 4 pin molex cords. my graphics card came with a 2x6 pin pci to 4 male 4 pins. Would Ibe able to just put this cord in between the two cords to make up for the lack of molex's on my psu. would this cause a problem in amperage and voltage. don't know much about that stuff but dont want to fry the innards of my computer.
