"hd 5670 do not need an external 6-pin power connector to run as it draws up power from the motherboard...."
what does it means....?
Does it means that it will run without any internal connector like when we give power to cpu we need to plug a four or eight pin power connector to the motherboard or it will run without any power connector(including power connected to the motherboard.....
The PCI-E slot will provide 75W of power, the card doesnt need anymore than that so you do not have to plug a cable from your power supply into it, you only need to insert it into the PCI-E slot no other connectors are required. Its similar to the auxiliary 4 or 8 pin connector for CPU power.
