Hi, I just upgraded from a HD4830 card to an Nvidia 460 GTX. This card however, requires 2x PCI-E power connecters. My PSU (Sea sonic SR2 500 watt) only has 1 PCI-E 6 pins and 1 PCI-E 6+2 pins connector. My worries is whether it's a good idea to use it to power the card. The card came with a 2x12 volt converter into a PCI-E 6 pin one. Should I use that one instead? I'm sorry if it's a stupid question. Thank you.
