Some GTX 1050 Ti require a power supply hookup.
This one, for example, requires a 6 pin cable from the power supply. Just make sure which card you're getting and what power supply requirements (if any) it may have.

You can always look up w/e card you are thinking about, on Newegg.com. In their pics section for each card, if it does require a power supply cable, it will be shown in one of the pics.
