So, I know how to work computers, I just don't know any of the fancy names for anything. I have a home-built PC made from random parts, with 8GB of RAM and a 180 watt power supply. I need a video/graphics card for it, but I don't know what will be compatible with that small power supply. Heck, I don't even know how to tell if something's compatible. Does anyone have any suggestions for an at least semi-decent graphics card that will work with it? Because the PC was made from random parts, I don't know a whole lot about what's in it. If this is an impossible query, I'm sorry; I'll remove it. Please feel free to ask any clarifying questions, and I'll try to find out answers.
