Yes, overclocking can potentially cause a PCI-E slot to fail.
I had a GTX 770 installed in a 16x slot and attempted to overclock it. The overclock functioned well, but after some time, my computer would frequently freeze. Temperatures reached 60°C during gameplay, and I checked every component without success. Eventually, I discovered the GPU performed better in an 8x slot. After replacing the motherboard with a new one, it worked properly in the original 16x slot. Did I receive a defective motherboard or did my overclocking damage the PCI-E slot?
MB might start to degrade or overclocking could take them beyond their limits. Likely a capacitor in the PCIe port failed. Using the 8x slot doesn't significantly improve performance, even with top GPUs. The GTX770 is advertised as a 230W card. Another chance is your power supply isn't sufficient, either in terms of power or quality. If this applies, your new components could also be affected.

mb might wear out or overclocking could cause issues. A capacitor in the pcie slot seems likely to be the problem. Using the 8x slot doesn't really help much, even with the strongest gpus. The gtx770 is marked as a 230w card. Another chance is your power supply isn't enough, either in terms of power or quality. If that's true, your new components could also be at risk.
Power supplies must carry out various functions. During an overclocking scenario they need to perform effectively. Voltage regulation is essential; if voltage drops, current increases and components may fail. Ripple refers to how much the voltage deviates from its set value, acting like a vibration that can harm parts. Overload protection is also important, safeguarding against damage such as fires. On budget power supplies this feature might be absent. Running a 230W GPU overclocked could consume more than 300W of power alone. Without knowing the exact components you're using, it's difficult to assess if they are suitable for overclocking. If the parts aren't built for this purpose, issues will likely recur.
Your PSU might have damaged a PCI-E port due to overheating or electrical issues.
Gigabyte offers solid performance, and Be Quiet provides a mid-range power supply. However, Nvidia suggests using a 600W PSU to effectively run the older, power-intensive GPU.
