Yes, I just recently purchased the NVIDIA GeForce 9600 GT for my computer because let's face it my factory intergrated chipset for HP model number: m8200n Media Center just wouldn't cut it for playing games. I just had it installed by a local tech here and it told me that my 300 watt supply would work fine with it. But I have others telling me I need at least a 500 watt for it to work properly. I'm clueless at this time of thing. Any and all help will def. make my day! Thanks!
