I haven't built a PC before, and I was recommended this build for my needs (gaming, 3D modeling for printing and art, CUDA for Blender).
Before I went and spent all that money, I was wondering if I could get some more help. My primary concern is the PSU. Using a basic online calculator recommended at least 600 Watts, but the one in the build is only 500. At this point I would lean to the safe side and get a 600 Watt PSU, but I want to triple check with people who know what they are doing.
