I have a Lenovo Idea Center with intel core i5 with 8gb ram and 1tb hard drive. I wanted to upgrade the graphics card but found that my pc has a max of 180 watts. I don't know if I can even get a graphics card since most of them recommend 300 w psc although I don't know what w psc means. I thought that someone with experience may be able to help me here. I would like the graphics card if there is one that works with less than 180 volts to be better than then integrated Intel UHD Graphics 630 that it comes with since if it's not it would be a waste of money. Please help me with the situation of people of the internet.
