EVGA Noob Confusion

[I_Got_Lost]

I have been looking over a build for a while (Below), i am mostly decided on the components. However i was reviewing the power specifications for the 780. and noticed this 

 

So i then turn to look at the rating for the EVGA power supply which had 4x12volt rails but each only was supplied with 20A (or am i wrong) but the 780 required a 12volt rail with 42A?

Is that still sufficient to power the 780? or do i need a different power supply.

[s3ns3]

the recommandation is for the whole system. 42A on 12v means a 500W psu. the psu is fine

^ This.

That psu is more than enough, even a 500w psu would be fine
