Question PCI-E cable in GPU stuck

[Vengeful03]

I am soon upgrading my GPU and PSU to support the new power requirements my system will need, my problem however is that the PCI-E cable in my current graphics card is kind of stuck. I was practicing messing around with taking out the PSU for when I had to and I only tried with the PCI-E cable in my GPU but I just wasn't able to get it out, I already tried googling it and didn't have much luck with a solution. I'm pretty sure I'm doing it the correct way as well. I push down on the top of the little black clip on top and trying to pull it out. It doesn't even give a budge though and I'm pulling pretty hard to the point my fingers hurt so I'm just not sure what to do. I'm not sure what to do so I'm hoping maybe someone here had a similar situation and can help me out

There are many locking mechanism types. Link us to a picture of your so we can see what you have.
You'll need to host the image on another site and link us to it.

Hopefully it wasn't overheating over time and fused the plastics together. Push the clip and wiggle side to side instead of pulling straight outward.
