PSU won't turn on when connected to 8-pin PCI of the GPU

I was gaming NFS Playback with everything on ultra without Vsync at 84°C (temperature that GPU always stayed during gaming) and then everything turned off, after some tests I realized that the PSU won't turn on when connected to the 8-pin PCI input of the GPU, and when the PSU is on and I connect, it instantly turns off...
Does someone have a hint if this is just some fuse from the GPU blown or might be something worst?
Also, some days ago I opened it because I saw a tape with some numbers in the PCB (probably from an RMA of the first buyer) and after I closed it, I forgot to check if the fans turned correctly, now I saw that the middle one couldn't turn because its cable was blocking it... Well, at least this explained why I always got to those temps quickly...
Just one last detail, when it worked if connected to PCI lane but not to those PCI power pins, two leds near it would blink, this doesn't happen now.
Specs:
GTX 1080Ti Gaming OC (Gigabyte)
i5 6600k
XFX XT500 500w (yes, the worst from that PSU tier list)

 

Edit: I'm currently using my old GTX970 now with those same 8 pin PCI connectors and everything is working just fine.


Some pins of the PSU seems a little burn.

And the GPU opened, you can also see that tape with numbers on the top

I'm surprised you got by this long running a 1080 ti on a shit 500W PSU, to be honest. 

Corps aren't your friends. "Bottleneck calculators" are BS. Only suckers buy based on brand. It's your PC, do what makes you happy.  If your build meets your needs, you don't need anyone else to "rate" it for you. And talking about being part of a "master race" is cringe. Watch this space for further truths people need to hear.

Uh...

You should get a better PSU, especially for a 1080 Ti.

Forgot to add, the PSU is working just fine, just the GPU seems burnt

The PSU can't provide enough power/correct to the GPU.

Get a better PSU ASAP - bad PSUs can die and take systems with them.

A PSU that destroys components several times more valuable than itself is not "working fine."

 

This is why people say not to cheap out on PSU. PSU's are boring and not sexy, even with some of them having Arr Gee Bee now, but they can take down your fun sexy components you actually care about and want to spend money on.
