Computer won't recognize GPU power


Jun 20, 2009
Hello all,

I just finished my build and it is running 2 4890s in Xfire. I tried booting it up but a screen comes up that says "you have not connected one of your video card power connectors to the power supply. Please refer to the "getting started guide" for proper hardware instructions. I looked there and couldn't find anything. I have tried using different pci-express power cords (but modular and non-modular) but nothing is working. I also checked the fans on both GPUs and both are spinning. And yes, Ichecked the "READ before posting about boot problems!" sticky and nothing was solved. Please help!
