I was curious about my machine and was wondering if I should stick with the power supply I have or upgrade to an 850W or 1000W power supply. From some sites that calculates power load, I am looking at around 640-670W. I am using this mostly for gaming, programming and some 3D modeling. I am also planning on boosting the RAM to 32GB down the road as well.
