    Hello,

    I have been researching whether or not the Nvidia GTX 770 will work in a 2009 Mac Pro. After some research, I have found that drivers are not the issue, however the power consumption is. I have seen people who have ran the GTX 770 no problem without a external PSU, or any rewiring in the machine, etc.. On the other hand, I have seen people having to run a external PSU for this. What I want to know is, will the Nvidia GTX 770 work perfectly fine without having to replace, rewire, or use an external PSU, etc. in a 2009 Mac Pro. I cannot seem to find a definite answer to this, and this forum is my last resort to find a definite answer.

    My current specs of the 2009 Mac Pro are as followed:

    2.66GHz Xeon
    Nvidia GT120
    640GB HD
    1TB HD

    If any questions arise, I will be happy to answer them.
    Thanks

    It's a question of power consumption. If you are only running one nice GPU, 1 Xeon, 2 drives and no other PCI-e cards, I can't imagine that's an issue. I've heard of some loaded up systems that start sound iffy but yours is relatively barebones. I would go for it sans external PSU in a heartbeat.

    I vote "you'll be fine"

    Just be sure to get a good 6 to 8 adapter that doesn't skimp on cables or connectors.

    I bought a modded version from MacVidCards and it runs perfectly, as they said though... if you get a good quality 6-8 converter then it should be fine.

    I've been running an overclocked MVC flashed Gigabyte 3 fan GTX 780 in my 5,1 Mac Pro for five months now. Using internal power with the two MVC modified eight pin connectors. Sweet Card and no power issues.

    I do have planned a few upgrades such as, another HD, possibly an SSD, and an Airport Extreme. Will this still be fine?

    ----------

    Do you have any suggestions?

    ----------

    First off, thank you to everyone who replied. It definitely gave me some satisfaction, :).

    What I want to ask as well is, will the GTX 770 Bottleneck with the single 2009 2.66 Xeon processor? The reason why I am asking this, is because I want to make sure it would be worth getting the 760 over the 770, if the 770 is going to bottleneck. It would be a waste to get the 770 if it were to bottleneck because I could get the 760 cheaper, run on less power, and have 2x 6-pin connectors, rather than adapters. Just a thought that came to mind.

    Thanks again!
