kougarI don't understand why they would change how the GPU was wired that way. So if the card thought nothing was plugged in it would fry itself, which is I guess what happened here. That's a very shoddy design if so...
ty_ger07Omitting the +2 will make the other 6 disabled. The +2 is part of a detect circuit per ATX specifications. Leaving the +2 disconnected will make it behave the same as if none of the wires were connected.There are a couple examples recently of these cards breaking when the power cables aren't connected.So, yes, I think forgetting the +2 could have killed it. Demonstration showing how a card uses the +2 connector to decide whether the connector is plugged in:https://www.youtube.com/watch?v=fRVSGFjKf4E&t=4m17s If I can find those "couple of examples" I will edit this post to include those links. But, from memory, Sajin (or was it HeavyHemi?) commented in one of those threads that he has come to realize that this has recently been shown to be a reoccurring problem, so I think he may corroborate. I think that maybe Sajin simply didn't consider that the functionality of those +2 wires would make the whole thing disabled, when he commented in this thread.
