[SOLVED] How many watts is the power supply of this?

Solution
A simple wattage number does not tell the whole story.
Older power supplies got most of their wattage specs from 3.5 and 5v,. not at 12v where modern processor and graphics cards need it.
Cheap units will deliver advertised power only at room temperature, not at 50c. or so which might be present inside a case. You can look at the data plate for detailed 12v watts/amps.

Still, you should be ok.
GTX1050 runs on pcie slot power only, that is a max of 75w.
