I chose that power supply, because it seemed to be getting great reviews. Since I am not too worried about price, I figured I could go with that one, not only because it its good, but I figured the extra wattage would be a safe bet even if it was way more than I needed. As for what I use my PC for, mostly gaming. I do dabble into photo and video editing a bit, but even though i love doing that stuff, I'm too lazy to actually do it, so I never get any better lol.
