It's not a MB connector as those are 8 pin (4 12 volt power on one side and 4 ground connections on the other) it is a GPU 6 pin connector. Yes you should use the 6 pin power as the card is rated at over 75 watts of power. The standard 16x PCIe slot is rated at 75 total watts and the extra 6 pin power connector provides up to another 75 watts of power. If you run any gaming software or anything that causes the card to work harder (thus drawing a higher power demand) it will go over the 75 watt power draw at the motherboard and could cause damage to the card or motherboard or both. The card comes with a Molex 4 pin to 6 pin adapter so as long as you have a power supply that can handle everything you have now plus another 75 to 100 watts of demand you should be okay. I hope this helps.
Sorry, there was a problem. Please try again later.I do not believe so. I have this card and all I have done is inserted the card into the MB and then you plug your power supply into the 6pin connector slot. So the power comes from your power supply not the MB. Hope this helps!
Sorry, there was a problem. Please try again later.Yes, supplemental power is required.
Sorry, there was a problem. Please try again later.I had a multi pin connector coming out of the power supply and it went into a connector on the MB.
