Their have been lots of reports complete with photos of the cards plugs melting , I contacted the company in england who built my last 2 pc's and they admitted that their had been problems with cards they had fitted. Regardless of what caused the problem , if your pc is under guarantee it is their responsibility to sort it. Realising that a melting plug could cause a lot more damage and put them out of pocket they have taken the decision to dump the supplied cables and now use cables custom made for them by Corsair.
So , if you are planning on getting a custom built rig it might be a good idea if you contact the company you intend to deal with and see if they do the same.
