@aa This is what I have https://i.imgur.com/clAruOR.jpg
4 - Sapphire 7950's
1200 watt gold Seasonic PSU
Sabbertooth 990FX
I was mining litecoins.
Not the best of setups as I basically set it up quickly before going out of country for a couple weeks.. but I had it like this -> https://i.imgur.com/oVFDKUc.jpg

You might want to try using one powered riser instead of the unpowered one, though I still don't believe that to be the issue.
Why replace the PSU? It's the top brand you can get..
I think the concern here is that the PSU is faulty and needs to be replaced by the manufacturer.
Edit: also, the people who try to push powered risers always go on about how you must use powered risers when you have more than "x" GPUs, but "x" is never the same number every time they go on about it.
The only downside is that this has happen on 2 separate machines both with different motherboard brands and PSU brands.. Doesn't seem like the PSU the defect causing this.. However, the plug is going to need to be replaced now on it.
I bought some powered risers to see if this will prevent this in the future but it's kinda hard to believe it was strictly just that.
The only other thing I can suggest is that you have really bad power in your area. Are you using a surge protector? It could also be that your power needs to be filtered more than your PSU can handle.
The problem with people who report such burnt ATX connections is that they never give all the details. Most of the reports don't even state what hardware they use, and the ones that did always reported using ancient motherboards that were never specified to run with more than one or maybe two GPUs, or power supplies that clearly didn't have enough power on the 12v. This isn't the case for you, so it must be something unrelated to your immediate hardware--only because I believe the chances of you repeatedly getting broken hardware from different brands is very low.
