Question PCI-E Cable Doesn't Fit GPU

[ItsRhio]

I've been gaming with my 2400g inegrated graphics for a few months, I recently bought the https://pcpartpicker.com/product/xH...rmor-mk2-oc-video-card-rx-580-armor-mk2-8g-oc and when I go to put my pci-e cable into it, it just outright wont fit. I tried for about half an hour, and nothing worked. Is it my psu's fault? My psu is https://pcpartpicker.com/product/Tc3RsY/seasonic-power-supply-ss620gm2

Can you post pictures of the PSU's PCI-e connector and the GPU power connector?

Are you sure you are not trying to connect an 8-pin CPU power connector? They look similar, but are not wired the same. Going by the specifications, your PSU should include multiple 6+2-pin PCIe power connectors for graphics cards.
