  1. Hello,

    I am trying to install the new NVIDIA Tesla K40 in our HP Z800 workstation with a 1000W PSU.
    I get the following error message even though I have connected the 6pin power connector

    Unable to determine the device handle for GPU 0000:42:00.0: Unable to communicate with GPU because it is insufficiently powered. This may be because not all required external power cables are
    attached, or the attached cables are not seated properly.

    Could anyone who has successfully installed the K40 please help ?

  2. You need at least and 8 pin connector. One 8 and one 6 pin connector is better yet.
