I have a EVGA 1500 Classified and 1080ti and I am mining Altcoins and when it hit full load it kills the computer. I just stuck a 650 Power supply on one of the two 8 pins of the 108ti video card and the computer does not die does this mean the 1500 PSU is bad?

    Sounds like a bad psu, or bad psu cable, it could also mean you're overloading the 1500w.

    Well I have a GTX 1080 TI, I7-7700k, 3 fan radiator, 240gb HD, AMD RX 580, and AMD R9 285 (mining rig). I can mine the 2 AMD cards togather fine as soon as the 1080ti kicks in computer shuts off. Now if I mine with just the 1080ti by itself other 2 cards are Ideal if runs a harder algorithm kills the computer. Now I have all 3 cards running for the past hour with the one 650 PSU 8 pin plugged in one of the 1080ti and has not killed the computer.

    Also it setup to mine with the power Target down to 80% so it pulling less watts. Just put the machine together yesterday. Also with just the 1080ti trying to mine it killed the computer shuts right down soon has it get to full hashing.

    That Yellow & Black Cable is what might be causing your Issue alone with them none standard Power Cables connected to them.
    You should not power a Single Graphics Cards using two separate Power Supplies as what it looks like you are doing here.
    I have 2 GTX 1080 Ti under the 1500 Classified PSU and have no issues and I am running 2 Separate PCIe Power Cables to both.
    What is the SuperNova Software (1.0.0.3) Showing, Post an image of the PSU usage.
    What are your Dip Switches set to on the PSU?

    Do you have the PSU setup as a multi-rail or single rail?  If switched as the multi-rail, you might just be pulling over the limits of one of the rails, tripping one of the protections and causing the power supply to shut off.  Try setting it as a single-rail unit and see if the shut-downs continue to occur.
