I am looking for a graphic card compatible with my HP Pavilion Desktop - 570-p030

I would like to upgrade my video card in HP Pavilion Desktop - 570-p030. How do I get the right one?

There are two problems.  One is that your power supply is 180 watts and I suspect a graphics upgrade of any quality will exceed the  180 watts rating..  The other ;problem is discussed here

Your motherboard is the same "Lubin".  Take a look at the picture and the placement of the 24 pin power connector

A full or 2/3 length two slot graphics card will not fit as that white connector with cables will block.  You will have to get a real "mini" for example, ZOTAC Geforce GTX 1050 Ti Mini

That card, shown here https://www.techpowerup.com/gpu-specs/zotac-gtx-1050-ti-mini.b3944 requires a 250 watt power supply and ideally 300 in my opinion.  

There is a guide here to find the product number of your system.  If you can  provide it I can possibly find if there is a power supply upgrade possible.   Since the connector seems to be a 24 pin I suspect you have a standard atx power supply.  Compare your power supply to a any standard atx power supply at ebay wherever and see it is the same size.  As suggested in that top url by @Grzwacz you could measure  and compare to that post.
