I am still trying to figure out where all the people that keep saying it was a bad connection (in the thread I started back on Aug 25), disappeared to?

Don't mean to play devil's advocate here, but dang! There is a real fire hazard here! I just upgraded my power supply from OCZ GameXstream 700w to a Corsair AX1200, to power 3x480's.

Um..... Don't want my house to burn down or anything. I have a family. I checked the 24-pin and it's dang hot.

Evga should recall all these boards and exchange them for Classy 3's.

I know I am going to contact them and demand a replacement. That's too many people with burnt mobos.

The heat your getting is the first signs, next will be jumping voltages on your 3.3v 5v 12v,dissapearing ram then will be random green screens, shut downs, then the phase is the burning of the 24pin=/ psu failure, or even worse frying of the entire computer if psu crap the bed from it, or a fire....
I've noticed games or benching that really pushes your cards speeds up the proccess of this happening.

Well I have had 3 HD 5970's running for a year now and my 759 for a year and half and now after reading this post I am somewhat nervous.  I to will shut down my board from now on when I leave it.  I just checked my 24 pin with my Raytek MiniTemp gun and top of 24 pin read 88F  and bottom 93F.  Will have to keep an eye on this.  Thanks donta for this post.

To my understanding, the problem has and must be the GPUs and not the board. The board/PSUs have problem on keeping up/ feeding the necessary voltage to the GPUs, causing the 24 Pin to fried. This is just my opinion.

I have to disagree.  You want to say that both NVIDIA and AMD/ATI produced cards that cannot run on basically any board out in the market today?  I really think this would be happening everywhere it they were the issue.  Many more people own many more of these cards than they do the motherboards.  In fact, your statement contradicted itself from 1st to 2nd sentence.  If it is the GPU that is the problem then the GPU is asking for power completely out-of-spec and you would have a boatload of PSUs dying everywhere.  In fact the highest survival rate would be in the high-end of PSUs, i.e., people with the TPQ-1200s, AX1200, etc.

Mine did it while o.c'ing my 480's (2) and playing Metro 2033 for about an hour, smelled something funny...rest is history! Only thing that saved my power supply was the fact that I use 24 pin extensions... sleeve them myself, so IT melted, not the power supply cable!! Still using it, just don't o.c. / overvolt my cards anymore...not needed anyway with 2 480's.

If you search around you will find people reporting this issue with several different gpus and psu's, all x58 boards mostly evga or asus. 480s, 5970, 5870, 5850, 4890, 4770 etc.  Even single card setups but primarily sli.  So is this really an overload condition?  Or is there a defect in the circuit board?

Are we saying this is a 480 problem only, does it happen with 470's, 460's ? Is it only Tri SLI, sli, or does it also happen with 1 card ?

It can happen in any multi-card setup pretty much.  I use HD5800 series as I stated before and it happened to me.

The reasion I'm asking is i have a 760 with a HX1000W, with 2(295+) for quad SLI, and a 758 with a HX1000W with 3(260's ) in Tri SLI, ( both of these have been running fine for over a year, the 758 for over 2 ); I also have a 759 with a AX1200, ( just built from B-stock ); and have yet to decide what cards are going in there. None of my boards have the additional Plug. As a B-Stock board, i know the warranty is 30 days. So I want to pick the graphics configeration that will have the largest bang for the buck folding, but also want to pick a setup, that I would not have to concern myself with the power draw, I am aware that all of my boards are EOL, and am not worried about the two with the A1 warranty, any recomendations ? 
 
According to EVGA "This only happens in specific scenarios, it is unlikely that you would experience any issues." But if I were aware of the "specific scenarios", I would know what to avoid. ( E-Mail from EVGA )  

I know The 6 pin officaly can provide 75 watts, and a 8 Pin 6+2 150 Watts,  and many of the cards have 2(6 pair plugs), so thats up to 150 Watts per card max, from two PCI-E cables. But I am not sure how the system decides what comes from the Plugs, and what comes through the PCIE lanes. I do know that the max a PCI-E lane can support is 150 watts, But I do not know if curent draw can be limited via BIOS adjustment, or directed to the plugs vers the Lanes.

I also am aware that E*I=P so 12*I=75 Watts  so,  6.25 amps per Pci-e plug max, *2=12.5 Amps, + the sockit is rated at 5 amps, so 12*5=60 Watts,   and 150+60 = 210 Watts, Yet Nvidia lists the mac card draw at 250 Watts ( for a 480 )assume that's not overclocked .(215 Watts for a 470), again not over clocked,  and 160 watts for a 460. ( again not overclocked.) ( not sure if/which of these cards use the 6+2 ( 150 watt plug) as apposed to the 6 pin 75 watt plug.

I would love to Have a EVGA EE, chime in here, and tell me what is safe to Buy, and what I should avoid. I don't blame EVGA, the boards were built with the features they were bult with, and designed to handle what was out at the time, I know they do what they were built to do, i just don't have enough specifics, about the design, to make an informed buying decision. 

I know, what some of you are going to say, we buy these boards to push them to the limit, Just need to know what the limit is ? I also remember how few 1000W PSU's were available when I first bought my 758, and you paid a arm and a leg for them, especialy if you wanted PC power and cooling .

Already have a reply from EVGA and I don't like it. I quote: "the issue is a rare occurrence that only happens under specific system configurations. "
