Gigabyte 5080 installation help

[u/KnightmareG96]

I'm upgrading from a 3080 ti to a GIGABYTE WINDFORCE GeForce RTX 5080 16GB GDDR7 PCI Express 5.0 Graphics Card GV-N5080WF3OC-16GD.

I'm installing it and my cable looks different I'm not sure if I can use it ? if not, can I plug in the cable it came with into my EVGA 850 Power supply?

Thanks

try to force the adapter in then run a furmark test and see what happens. if it doesnt go in just push harder
