I have some power connection questions if yall dont mind. My card came with a dual power connector, Im wondering if I a. Need this connector. B. should hook up this connector with 1 or 2 power inputs From my PSU. Or c. Just use the pci-e power from my XG Vortec PSU. I;ve had the card for some time now and was using just 1 power connector from the PSU, but Im not sure if its getting the power it needs. I just bought the XG Vortec 600w and its got the PCI-E connector now so should I just use that?
