You have a 460W PSU and the 1050Ti only requires 300W so it should be fine. Just make sure the card is under around 9.5 inch in length.
Another question for Sam Tree:   Will either of these cards work in the XPS 8500? GeForce GTX 1050 Ti 8GB GeForce GTX 1050 Ti 11GB
XPS 8500, GTX 1050 Ti compatible?
