I was thinking about uprading my hd5450 to a gtx550ti, but after I asked a few people, was told that my thermaltake psu might not be able to handle the power draw. I'm not a gamer, more into hd video/photography/entertainment. I want to upgrade to something that will work in my system without upgrading the power supply. I need something efficient, but again I don't think I would tax the system that much for the type of computing that I do. Any info will be appreciated. Looking at cards up to $150. Thank you.
