Hey, I'd just like to know what the power supply (how many watts) of the new HP models are and one of the old models (link below). I plan on just installing my own video card afterwards so I wouldn't have to purchase a high end PC, but I can't really decide on which video card until I know the power supply. I've looked everywhere, and on the future shop website (I'm buying it from there) it just says "Information not available". Thanks in advance for any answers. http://www.bestbuy.ca/en-CA/product/hewlett-packard-hp-pavilion-desktop-computer-featuring-amd-athlon-ii-640-processor-p6710f-p6710f/10161408.aspx?path=d521fae77d31f0354c60fd96939b8230en02 http://www.bestbuy.ca/en-CA/product/hewlett-packard-hp-pavilion-desktop-computer-featuring-amd-phenom-ii-960t-quad-core-processor-p7-1020-p7-1020/10172595.aspx?path=a27c92b2241884c2cf30378642114eaaen02
