I cannot make anything out on the label on either photo. However, what I also do not see are GPU power cables. So the best GPU possible is going to be a Geforce GTX 1050 Ti.
I can see that that is an Asrock motherboard, but cannot make out which one. If you can tell us the exact model then we can recommend a CPU upgrade.
