Nice, I just had this same issue with E760 and Antec 1200 tpq, same 2 pins melted inside the 24-pin socket. I hope this is not a recurring issue as I just received a series of RMA boards with 1 problem after another... 3rd time is the charm I hope.
Well, it happened again, same 2 pins melted inside the 24-pin socket...system dead.
Not what I wanted to hear as I just bought a TPQ-1200 to pair with my E762 
The 762 has a 4-pin molex to provide extra power to the PCIe lanes... You should be fine. This is an issue where 2 GTX 480s are drawing so much power through the 24-pin connecter its melting those 2 pins..... A designed flaw for both the card and the E760 HRPuffnstuff
Uhhm did you rma the ps or is the same one that had the original problem?
Yes, this is a new psu or was.... need to rma it again but this is just going to happen again. Perhaps evga will step up and offer me a E762 or maybe they have another board coming out with supplemental power to the PCIe lanes.

I have received the RMA board back, PS RMA is in the mail back to me. But the more I hear about this happening the more worried I am to run my Triple SLI setup again. Currently I am just on one 480 as my backup PS is only 750W. This is just great almost 3k invested in a system and I can't run it for fear it will burn those connectors out or even worse...burn my house down

I just have two GTX 260 cards in SLI right now, but I decided to use that molex power connector just to be on the safe side.

you guy's Are Scaring the living **** out of me ><
760 759's burning up thank to two GTX 480's >.>!
I got a 759 but Atm running 2 GTX 285(test .loan) with no problems!
but i intend to get Two GTX 480's
And you all talking about motherboard melting pins really sacres me xD
o own a Silverstone DA1000
Very nice PSU
but i think people who have this issue!
Shoul post
PSU brand and Wattage
motherboard and code (7xx)
Used video card(s) and what Pcie slot used!
might help to isolate this!
like some said i can be also psu's
multiple 12v rails and single
Cuse if i remember the 759 need a single rail 12v?
the 760 can work fine with multiple rail 12v

From looking at the pictures, I agree with Heavyhemi. I have dealt with connectors a lot and it appears to have been a poor electrical connection that heated up. When you have a bad contact connection the pins will act like a heating element. This is evident by the discolored pins. When you get the new components make sure the connecotrs are completely seated.

Thnks...I am aware of this kind of issue. I have a couple of questions? Since you and Heavy are knowledgeable in this area. What do wires and connections look like when they exceed recommended specifications? Also the spreading of the connectors in the pictures I present. Could they not have expanded due to the amount of heat from the amount of power going through the area, if the power is exceeding specifications? And as they expand, in turn making it even worse...as it creates a poor connection, creating even more heat etc etc. I also have to wonder... Why would MB makers start adding 4 pin molex connections to their boards? Is it due to bad connections or the power draw is exceeding the recommend specifications on the 24 pin yellow wires? And therefore must be subsidized with added power via a 4 pin molex connector...basically taking the load off the 24 pin. So a basic question to the motherboard makers.....what is the purpose of adding a 4 pin molex connector to the boards? If it is indeed to help the 24 pin out. I am a little disappointed no one saw this coming on the Classified 760 or other Classifieds that do not have the extra 4 pin molex connector on the MB. Over time it will become more clear either it will be a big problem...or just a few unlucky guys.

I had this happen to me also. I have a 759, the Silverstone1500watt PSU, and 3 gtx480. Mine didn’t melt as bad as the one posted here, but I was getting random shut downs. When I pulled my 24 connector the housing for the same pins had melted enough so that they broke off inside the board. Thankfully, EVGA replaced my board and Silverstone sent me a replacement 24pin cable. I have since replaced my PSU and removed a card. The real problem here is the PSU, the cables going to the video cards are just crap. They don’t provide enough power, so power is pulled from the 24pin connect, which results in the overheating and melting issue.

There is much truth to what this guy said. I do this stuff for a living. The PCIe power connectors may not have been supplying enough power to the vid cards, and when this happens the power will come from the path of least resistance, that being your 24-pin. The paradox is that when the burning started, that comes from resistance, and then they should be drawing from the PCIe connector instead. Did anyone ask him if he checked his TWO PCIe connectors on each vid card, were they plugged in? Any sign of contact burning there? What about the PSU plug end of the PCIe power cords? But here is the bottom line: Now he has burned contacts on BOTH SIDES of his 24-pin connector, and therefore will never get a good low-resistance connection there. Both the PSU and the mobo need replacement, SIMULTANEOUSLY or you may burn the other contact on the new device. Check the vid card contacts carefully and with a light source and magnifier. If they look burnt, replace the vid card simultaneously as well. Check all the plugs for backed out pins, when they are backed out it looks connected but is not or is a bad connection.

What do wires and connections look like when they exceed recommended specifications? Kinda like this:  http://www.mainelycontrols.com/pics/computers/Burned_ribbon_cable_wire_MMW.jpg And like your 24-pin burned connector. LionRed
Also the spreading of the connectors in the pictures I present. Could they not have expanded due to the amount of heat from the amount of power going through the area, if the power is exceeding specifications? And as they expand, in turn making it even worse...as it creates a poor connection, creating even more heat etc etc. See my last post, above. LionRed
Why would MB makers start adding 4 pin molex connections to their boards? Is it due to bad connections or the power draw is exceeding the recommend specifications on the 24 pin yellow wires? And therefore must be subsidized with added power via a 4 pin molex connector...basically taking the load off the 24 pin.
So a basic question to the motherboard makers.....what is the purpose of adding a 4 pin molex connector to the boards?
The extra power connectors became necessary as CPU power draw increased. They are for today's hot CPUs. That's why the connectors are near the CPU.

Actually, the 4 pin molex connecter, like the one on the 4-way classified is for the PCI slots, adding power and it would help cure the problem of the 24pin melting. To add power for the CPU like HalloweenWeed said, they are adding another 8 pin.

I spoke to Antec today and explained the situation and they said it was a problem with the motherboard. The tech explained to me that the graphics cards are asking for X amount of power from the PCIe lanes and the power supply simply provides what it is asking for. If it was an overload situation the PSU would shut down.
As far as a bad connection, I could agree with that but this is the second time now (within a month) with a different mobo and PSU and this is happening to other people aswell so something else is going on that needs to be addressed.
Are a pair of GTX 480s pulling that much current from the 24-pin connector to cause them to melt? How much heat is required to melt the plastic pins and fuse it with the plastic of the socket? Why is OJ, who got away with murder, so stupid as to stage an armed invasion to retrieve sports memorabilia that no one cared about that landed him in prison?
These are burning questions that much be answered!
I am not looking to rma my board and psu every few weeks!

I sympathize with you, really. That said, this is a known prob, beginning with the 5700 series vid cards (or was it 4800 series?), esp when using 3 on a mobo. The Nvidia 400 series cards are just as power-hungry, maybe even more. This prob exists with other brand mobo's as well (google it). So I have to agree, the prob needs to be addressed, as does the weaknesses of the Intel ICH58R (USB failures, dropping RAID drives). I have read that the new X68 chipset uses the same southbridge and thus will prob have the same prob! Part of the prob with the computer industry is they are so far ahead in development they refuse to fix what they have already churned out. What I am saying, is the X68 was probably already in development when they discovered that their southbridge had a weakness, and refused to allow the redesign of it to delay the development of the new X68, since it was working 'good enough' for most folks. Your prob is no exception. Who uses 3 vid cards anyway, or top-of-the-line gongo vid cards? Enthusiasts. And enthusiasts are just a small percentage of all their sales. 90% of ppls just use a single cheap graphics card, or onboard vid. I have even heard rumors of eliminating the PCIe (and PCI) lanes entirely. Sorry but you and I are just the minority, we get least consideration in these matters.

I willl attemp to answer your questions, Connectors pins are made to work within a wire size range. Connectors pins will be sized for a certain gauge wire range and is designed to handle the current for those wire sizes. As to what they look like, It would be pretty obvious if you see a bunch of 10 gauge wires jammed and crimped into a 10 gauge connector pin. Which it is not, in your case. The spreading of the connector pins could definitely have been an issue. Pins are designed to compress and expand when they mate for a tight fit. In your picture the spreading of the pins does not look normal. It looks like the pins were jammed open too far. How? It could have been anthing from a base pin to the motherboard seated at an off angle to the connectors not mating properly when it was inserted. That expansion was probably not caused by heat. As I understand it my E760 does have extra 8 pin connectors to supply more power to the CPU. There are 2 of them to the left of the CPU. And the video cards get the extra power they need from the 6 and 8 pin PCIE connectors. I would not be too worried about this recuring again. Just take care and visually inspect the pins and insert the connectors straight and not at an angle. These things do not happen very often, but poor connection do happen and is definitely possible with these connectors.

ya know speakin of power draw on the 4xx series. This is a good video that shows just how much power they can consume if allowed. Now he is running a twin PSU config, and explains what is on each PSU during the vid and shows the consumption on each psu. Watch the PSU's get real hungry about 6mins in under heavy load. http://www.youtube.com/watch?v=iEIkmuVvldA

Just had the same thing happen to my 4x classified after installing 2 480 hc ftw's. I think that the 4 pin molex does need to be in for two 480's or more. They said to have it in for 3 or more cards, but they should say for 2 or more for this new generation of gpus. My antec 1200 ran perfect for 10 months prior. The 24 pin was installed properly and not touched for 9 months prior, when I installed a full board water block. This has to be from too much power being drawn from the cards. I'm starting to wonder if they should have put two lmao. These cards are excellent though, I kinda wondered if that molex was needed when my lights flickered during benchmarking two 480s.

Wow, I definately would have put power to that 4-pin molex just for good measure. EVGA took care of me and upgraded me to a Classy 3 which does have a supplemental 4-pin molex which I am using... So far so good

is ur mobos fault! my powersupply did the same thing to my classified E760 sadly the 480's is drawing too much power that it melted two of the plastic on the 24 pin atx connector and melted all over the two mobos pins. thats why new mobo these days like rampage 3 and the new e770 has that new 4 molex connector so instead of drawing too much power on those 24 pin connector it will draw power on those 4 molex connector. so if ur mobo has a 4 molex connector next to the pci-e slot and ur using two 480s or more better plug a 4 pin molex connector to it so that it wont burn out the 24 pin. and also overvolting ur gtx 480 to its stock voltage will increase power consumption and if u dont have a 4 molex connector like the old e760 ur chances of burning two of ur 24 pin connectors are pretty high.

Evga has upgraded my 760 to a 762, this will ease my mind about running GTX 480's triple sli configuration. SilverStone Tech, also saw fit to replace my 1500W PS and the 24 pin cable.
No damage (that I can tell at this point in time) was incurred to any of the other components...CPU, Ram, Hard Drives and none of 480's got damaged. Even the HD's that disappeared are working fine.
