Well, if your warranty only lasts if you don't open your computer, how is it that you would even using the GTX 1050 TI?
Will the 1050 TI fit into your case? Yes, it will.
Will it connect to your motherboard? If you have a spare PCIE slot, Yes.
You also require a 300w+ Power Supply, so as long as your PSU is rated for that then you would be fine.
