What PSU voltage would I need for the following build:

Intel i5 3570k
MSI z77 MPOWER
EVGA GTX 680
Corsair vengeance 16 gb 1600 mhz 2 module kit
OCZ Vertex 4 256 GB
EK DCP 4.0 pump
EK Coolstream radiator XT
(extra volts for fans I might add after all the parts get here, as well as a blu ray reader)

Also I would like the possibility to upgrade with another graphics card(maybe) and another SSD (for sure), also upgrade my memory but I doubt that makes much of a difference.

want overkill http://www.newegg.com/Product/Product.aspx?Item=N82E16817703028
Here is Guru3D's power supply recommendation:

GeForce GTX 680 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 680 SLI - On your average system the cards require you to have a 750 Watt power supply unit as minimum.

If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina.Source: http://www.guru3d.com/articles_pages/geforce_gtx_680_sli_review,4.html
