The most obvious place to upgrade would be first the PSU and then the GPU.
thank you. Do you have any psu recommendations? (i am thinking about a gtx 1050 ti for the gpu)
If you're on the budget side, usually the 450/550 Corsair CXM (the new one with a black and white label, the older line with the green one was mediocre) or the Seasonic 520/620 tend to be available at the best prices. Do check your existing PSU to see if you're using a standard PSU (OEMs sometimes use proprietary ones and the public documentation tends to be less than helpful).
