I have a Gainward GeForce® GTX 560 1024MB graphics card which has 2x 6 pin PCI-E inputs assuming as a power supply. I don't have a power supply that has those connectors but it came with 2 molex adaptors, one single and one that forks to two separate ends. The only problem is, they only have 3 pins. I was just wondering if any harm be caused if I connected it to regular molex cables. Thanks.
