    Default E760 Classified Mobo + SLI GTX 480s = melted 24 pin connectors

    Hey all, I'm having, ah, 'issues' with my mobo and graphics cards. I've posted the warning to other forums so here's simply a link to a thread in which I've described my problem. I hope it warns a few of your blokes off from making a mistake like I have, and plugging in yet another PSU to meltdown....

    You state in your first post that.
    (one pin was the + and the other was the ground)
    Looking at the pics however, the two wires are the 12V+ wires.

    I'm surprised that no one has blamed the actual connector on the PSU for part of the issue. The reason I say that is the fact that in the second picture you can clearly see that two of the other pins are not fully seated into the 24-pin PSU connector (pin 7 & 22). I've seen several 24-pin connectors show signs of burning (not to failure though) due to one of the pins not being fully seated. Thats one bad thing about most of them using black housings... makes it harder to spot the early burn spots that show up easily on the white ones.

    I didn't see where it was mentioned if the motherboard was replaced after the first instance of this? I'm guessing that the board didn't get changed. Which would leave me wondering if the first issue did enough damage to cause the 2nd psu's connection to not be 100%.

    Yep. That'll do it.

    Whenever you see burned hot wires like that, it's because the grounds are not making full contact. You MUST have good ground wire contact or your wires are going to get hot.
