New graphics card help


May 23, 2011
Well i have a lame inspiron 531s (yes it's slim) with a measly 250 watt psu. I dont want to build or buy a new rig since i dont play the latest demanding games, so far iv'e been running a PNY Geforce 210 for about 5-6 months with no problem, but i really want to upgrade, and it would be really nice if anyone could refer me to a link of where to get a new psu (has to fit a slimline case) and a good low profile gpu my budget being $100.
