Both are good calculators. In my personal opinion, 250 is low.

Answer 2

You can search for power supply calculators and the other answerer left a link.  I don't know what your budget is for this but the link is for an antec 500 watt 80-85% effiency PSU that's SLI ready. under $50.00  and free shipping. I received mine Saturday and installed. Modular cables and three 17 Amp 12 volt rails. Four and eight pin connector a nice upgrade for a good deal. Good luck

If you order, choose budget 7-9 day shipping for the free shipping, it is default for $5.49 if you don't
