Your lucky then. I used mine for a while too. First failure killed the power supply. Short circuit protection failed I guess. They after I thought I had gotten rid of all of them I discovered I still had one on the 6 pin on my 7970 which failed. Now I'm still waiting for my 7970 back from rma. They short in the connector itself (heat melts plastic just enough to short 12v and ground which conveniently are right next to each other), like the other guy said its not the wire that fails. Its not worth it.
