Did you actually try using 1050 ti on your current mobo or just purchasing in advance? Try the card first if you didn't already.
As for your question, yeah, GA-B75M-S should work fine with 1050ti.
I did try and it didnt work later on i found out that the bios on the gpu is UEFI and my mobo has legacy bios so Im just getting the new one cuz I know it has UEFI bios
