Well, some of may or may not know I suffered from 2 melt downs of the 24-pin plug. 2 E760 boards down along with 2 Antec 1200 TPQs. EVGA upgraded me to the e770 Classified 3 that has the 4-pin molex plug at the bottom of the board (which I use). Antec replaced both PSUs and the 3rd one I received was brand new.
 
All of the other gear is the same. 2 GTX480s, CPU, Memory and so forth. I was able to get ahold of a 3rd GTX 480 to run a 3-way SLI setup in an attempt to see if the problem was indeed corrected.
 
I put these cards through the ringer. Ran them at FTW speeds (751 core, 1501 Shader, 1900 mem), O/C'd my 980x to 4.2Ghz. Video cards where at MAX settings. I ran furmark for 20+ hours, Counltess 3Dmark Vantage, Heaven Benchmark and Fluidmark. Played the games I normally played when this issue arose. Crysis, BC2, SCII and my staple game Lineage 2 (looks fantastic at 96x AA lol).
 
After 2 weeks (I received my board on Oct 1st), I am happy to report the 24-pin plug shows no sign of any problem. The addition of the 4-pin molex seems to have corrected the issue. I hope this information was helpful.

Oh thank God! I have a classy 3 and 2 480s and a 460(physx) and I was worried about this a bit. I used the molex as of yesterday, but truth be told, I was a bit scared it could happen anyway. I will make you a deal...If it happens to me, I will contact you immediately. Do the same?

sweet man so you didnt have one of those rare configs they talk about in dontas thread?

Actually he did he went though more motherboards and psu's than i did read his post... As for me I am running the classy 3 now as well the 24 pin stays cool to the touch and oddly my gpu temps have dropped idle 3-5c and load 10c guess they are getting the power they need with the molex at the bottom...

woojyee

Nope, I am not much of an overclocker so all this happened at stock speeds with just 2 GTX 480s. Which is why I borrowed a 3rd and put the Classy 3 to the test.

Hey I am not a big overclocker as well was running at stock speeds too=/ I do one overclock to satisfy my inner epeen then pretty much run at stock=/

its ok i do not like not having digital output, and i forgot to press F6 on windows install.... to install my SATA III Drivers so windows can boot without the install dvd of win7 in my drive, oh and no nf200 chip....

So does this mean us with the 759's can evolve to the e770?

 
I would not advise it unless you want a technical downgrade or you really are not confident doing the Molex mod yourself.  I am the "someone" dona1979 is referring to above and the results are staggeringly nice.  I am actually shocked how much more stable the system appears.
 
Oh and 24-pin connector heat?  Gone.  Connector is cool to the touch even after being taxed to the max that my system can do (well, not quite max as I could start pushing 4.7GHz again and 1100/1300 on the GPUs but that is another story ).
