The 'MINIMUM' is 600 watts Qality power supply, but I would go for an XFX 650 Pro core powersupply for that system settup, or a similar quality and price power supply. The graphics card on its own uses 250 watts, and the rest of your system another 100 at least.

The one you chose in your build is a great power supply and is sufficient to power your specs.

I agree SR-71 blackbird, 1) from the http://au.pcpartpicker.com you will see the estimated wattage is 458W, I will add 100W for more headroom. 2) from other review, you can see the good 550W will be enough for your PC, if you use only single gtx780ti http://www.guru3d.com/articles_pages/msi_geforce_gtx_78...

The PSU TruePower Classic 650W is more than enough, even you can get the Antec HCG-620 ( $100) is good enough too. http://www.pccasegear.com/index.php?main_page=product_i...

That true power classic 650w is made by SEASONIC , so you know it's solid.
