Should I be nervous about using this PSU with a GTX 760 and a AMD-FX 6300?
It should be fine as long as you aren't overclocking, but you will probably put a lot of stress on the PSU and it won't last as long, I recommed upgrading your PSU, but yes it should be fine. I ran my R9 270X on a 500W cheap PSU with an Amd Phenom and it worked fine but it would crash every so often. It depends on the quality of the PSU as well. You could always underclock your stuff as well but you would lose performance.
