about graphic card

Solution
You need some sort of PCIe based port.
Like I said, most/all commercially available external graphics enclosures use thunderbolt.
Not sure what video you're referring to, but Linustechtips did it hanging off a custom M.2 card from a PCIe/NVMe M.2 port. I doubt your laptop has such a thing.
That's what I was afraid of. You bought a graphics card that gets installed in a desktop computer, not a laptop. Also, your laptop doesn't have Thunderbolt, which is what most/all external GPU enclosures use.

Return the GTX1050Ti. It's of no use to your laptop.
 


BUT i saw some videos which use desktop gpu in laptop
