You guys are all awesome, thanks! For those curious it was a 980X involved and liquid cooled, although the PWM/connector area did have a 120mm fan blowing on it.
Was the first casualty I've ever had from overclocking anything and the motherboard itself was such a good board that it was painful to lose it like that. (Don't get me started on Gigabyte's X58 hardware) I assume both are easily repairable but I just don't have the soldering skills nor wire tools.
Regarding the connection problems that was the information I was given. I know the connector was fully latched as I had some trouble disconnecting it afterwards, but I will admit the PSU itself had seen quite a few system rebuilds and motherboard swaps in its lifetime.

Ahh, didn't realize that! Makes sense in hindsight now that ya point it out.

After this happened I started wondering this myself...
