Hooking this up - Do I need occupie all 14 pins or just either the group or 8 or the group of 6. Again the power requirments and plug in's keep changing over time and the manuals are worthless these days. At one time they got all the power from the pci slot. Then they added a four pin connector like to the hard drive. Then they added a special four pin square connector and the 4 pin connector like the hard drive but at that time it was either or... use the special four pin or the in line four pin.
So do I need occupy both groups of pins the group of 8 and the group of 6?
Yes Thar, you need to connect every slot in that. This means that your power supply NEEDS to have a 6 pin and a 6+2 pin adapter at the very least. If it doesn't then you have to upgrade to a better power supply.
