asus rampage iv black edition
corsair dominator platinum quad chanell 2400mhz 64Gb
now i need the power supply unit and i wonder between:
corsair AX1200i
corsair AX1500i

the 1200i will be enough for your build

You don't need a 1200W power supply unless you are planning to add another GTX 780 later down the line. A good 750W-800W power supply like a Corsair AX or EVGA Supernova G2 750W will be more than plenty for just a single GTX 780.

If you are planning on going SLI further down the road then get the AX1200i

If those are your two choices then I would go with the 1200.

Take a look at this for some PSU.
