Yeah the connectors were ordered direct from Nvidia, which is why it took a bit longer than they first expected, would have been a quick next day job if they had the connectors in stock.Is there no way of contacting the company that fixed your GPU to verify if the connector is the revised version?
Only thing I thought looked different was the sense pins, they seemed to be set a little further back than the old connector. And it felt like a tighter connection overall, guess time will tell, but I'm not sure the new connector will alleviate the problems anyway, since most people with melting issues all report that the cable was fully seated.
Fingers crossed its all OK now, but have to say I'll be a little on edge from now on lol
