K404 Posted October 5 Share Posted October 5 Hi all! I have a strange problem with a card, i'm hoping to get some info or ideas. It has the solder holes for an 8-pin power plug, but only a 6-pin plug was installed at the factory. I get the above error message before proper POST. vCore is present. I have tried shorting the other 2 pins and I have tried wiring them to the appropriate 2 pins of an 8-pin power plug. Same error message. The PC has booted to Windows literally twice with this card installed, which makes me wonder if there's a bad connection somewhere but i've not been able to find it. How does the card/BIOS decide that the power cable is unplugged? Do false positives exist? Can this check be pypassed? Thanks! Quote Link to comment Share on other sites More sharing options...
TerraRaptor Posted October 5 Share Posted October 5 You should bridge grounds of the connector Quote Link to comment Share on other sites More sharing options...

K404 Posted October 5 Author Share Posted October 5 Didn't work There's a chip beside the power plug. I'm beginning to wonder if its damaged and putting out a false warning. Quote Link to comment Share on other sites More sharing options...
K404 Posted October 5 Author Share Posted October 5 I desoldered the chip beside the PCI-E: it POSTed and booted into Windows on the first attempt!....although I get the same message if I do a warm restart. Meh. it's a bit of progress! Quote Link to comment Share on other sites More sharing options...
