How many watts required for Gtx1050ti strix oc edition ?

GPU is only part of the equation. What about the rest of the system components?

nVidia specs page says Gtx1050ti can draw 75W and recommends system power at 300W. With other considerations I would say at least a 500W so you don't worry about it. Or a 600W so you can boast about it.
