I cant get a picture of my PSU sadly, I heard that the video card uses 75W thoughI presume that's an OEM PC ? Nvidia actually recommends a minimum 300 Watts PSU for the GTX 1050 Ti. I can't find the exact model of your PSU. Can you post a pic of the PSU's label ? But still, 220 Watts seems very less, IMO.
Can you upgrade your PSU ?
