My friend has a Compaq Presario SR5450F (http://www.newegg.com/Product/Product.aspx?Item=N82E16883109011), plays WoW only, and wants a graphics card upgrade with the minimal amount of money. I have the following PSU that I'm willing to part with: Antec SL300, 300W, (+3.3V: 20A, +5V: 30A, +12v: 19A, -5V: .5A, -12V: .5A, +5VSB: 2A) (No link, ~2 years old with little to no use) I wanted to get an opinion on which video card would be best and will that card fit into that case. I think the 9600GT Low Power (+12V @ 18A and ~59W, for example http://www.newegg.com/Product/Product.aspx?Item=N82E16814130485) would be pushing the PSU limits. Otherwise, I think it would be along the lines of the 9400GT/4350 (based on the recommended "power consumption"). If that doesn't work, I could swap the 300W with the 380W I have in my HTPC, which is the following: Antec Earthwatts EA380, 380W, (+3.3V: 20A, +5V: 20A, +12V1: 17A, +12V2: 17A, -12V: .8A, +5SB: 2.5A) http://www.newegg.com/Product/Product.aspx?Item=N82E16817371005 I really don't want to part with the 380W, since it seems like a decent HTPC PSU (I might add a nVidia 9-series card for CUDA and CoreAVC), but I believe I have more options with the types of the card. In general, I'm mostly unsure of the card length which this case can handle (I don't have access to the actual PC). I was thinking the 4850. Any suggestions would be appreciated.
