I didn't think I would be able to run anything over a 8400gs with my lowly 19a. Seeing how this is just a temporary fix for an old pc untill I can afford a real gaming platform I am really nervous about spending 80 bucks on a GPU to have it not work. This specs on the 9600GT is saying minimum 350w with 12v/20a. I am only working with the 19a so I am really nervous about it going up in smoke after a month or two. The 9500GT says 18a so I should be able to push that ok. But it is weak on the gaming side. I would really like to be able to use a HD 4870 or 9600GT. Can anyone else vouch for these working on my PSU?
