I've build my first pc, the current build is http://pcpartpicker.com/p/sRqFkL/ except for the video card. I want to buy the 780 Ti because it's on sale on my country (Mexico) for $300 dlls, I want this because it's better that the 970 (and in my country 970 is arround $420 dlls min) So, the problem is that I only have 500W (PSU EVGA 100-W1-0500-KR) and this card supposedly needs 600W I'm not planning to overclock the card or the CPU, so I wanted to know if I can install on my CPU 780Ti with only 500W
