I am also Looking at upgrading a video card from a radeon X300 but have some concerns. The power supply that I have in my computer is proprietary to Sony so upgrading the power supply seems diffucult

. It says that it is a 365watt power supply unit. I made the mistake of ordering the wrong video card (it requires 400 watts)


. My system is running windows XP media center edition and is a Sony VAIOŽ VGC-RA820G. Was hoping for some advice so I don't make another mistake.
