    Hello! I tried to install a GTX 650 into my Mac Pro, but it didn't boot or chime. It didn't make weird noises. I removed the 650 and the PCI cable and reinstalled the original card, but it still won't chime. Thats about all I know. I can't do a PRAM zap since it doesn't supply USB power, it hasn't booted that far yet I guess.

    No I just need to know what model it is, cause the architecture is a bit different! So the system worked gray with the stock graphics card, was it the GT 7300? and then you put in a gtx 650 and then it stopped working?

    did you connect the 6 pin power as well?

    You can reset the PMC.

    Unplug power and hold power button down for 10-15 seconds

    then replug power and try again
