[SOLVED] CPU power cable upside down

Okay, I did something really embareassing.


Bought a new motherboard and CPU and did something stupid.

So I manged to plug the CPU power cable to my motherboard upside down. (Yes, with force)
It was a really tight space because I was to lazy to take the fans out again, so I thougth that was the reason it was so hard to plug in.

So it didnt boot, obviously.
It just made some electrical noise and flashed in the CPU coolers RBG light.
So I thought, maybe the CPU cable is not all the way in, so i go ahead and try to push it in further, still doesnt boot, obviously.

So I check other cables and re seat the ram and so on, and try again. Still not booting.
I decide to swap out the CPU power cable with a new one, and thats when I noticed it was upside down. (after spending 15 minutes trying to pull it out)

I swap the cable out with a new one and it boots, and I think I have been really lucky.

4 hours later I get a BSoD, with a WHEA_UNCORRECTABLE_ERROR and another WHEA something. And in the Windows error log its a kernel power 41 critical error code.
And its happening every 5-10 minutes. Sometimes it will just hitch and I have to hard restart.

Tried updating drivers, windows reinstall like 3 times and so on. Was hoping it was something wrong there but.

I put my old motherboard and cpu back and everything works fine, so Im guessing I destroyed the new motherboard or the CPU, any thoughts?

Not gonna mention what parts it was because you guys will cringe, and yes the CPU and motherboard is compatiable.
 
Solution
next i would inspect the cpu pads and the motherboard pins to see if they are charred.
after that I would make sure the bios did not get corrupted, ie reset it to defaults. boot windows
and make sure there is no overclocking drivers. I guess i would also confim all of the voltages from the PSU and make sure it was not damaged.
you should pull the cpu power connector and see if the header pins from the motherboard melted and are inside of the connector socket. if so you would just replace the socket and header pins. might just be a charred spot. I have seen someone do this before, but they just did a return and got a new board. the vendor just figured there was a short or manufacturing defect. if it is charred you might just be getting a bad power connection.

Already did that, they look fine.
Do you think its any chance the CPU got damaged somehow?
Or just the motherboard?
