| From: o1bigtenor via talk <talk@gtalug.org> | Can find pin outs - - - - none of the cable pics are clear enough to count | the number of individual runs. <https://allpinouts.org/pinouts/connectors/power_supply/pci-express-pcie-6pin-power/> <https://allpinouts.org/pinouts/connectors/power_supply/pci-express-pcie-8pin-power/> Or better (but look way down, from "6 Pin PCI Express (PCIe) Power Cable Connector" on): <https://www.moddiy.com/pages/Power-Supply-Connectors-and-Pinouts.html> The original 6 pins are all assigned 12v or ground. The extra pins in the 8 pin connector are just grounds. All seem to be connected. Why two more grounds? Because the 8-pin is supposted to supply more power and "they" added pins to make this new requirement unmistakable. Or maybe they just actually needed two more grounds. You said one pin on your connector was absent. => your connector isn't right I don't know if this matters for your new card. Clearly it does not matter for your old cards. Is the pin missing for each of the connectors used for the old video card?
