Graphic Card: 2 ASUS GTX780-DC2OC-3GD5 in SLI
Motherboard: Asus Rampage IV Extreme or Black Edition
SSD: 2 corsair Neutron GTX in Raid 0
HDD: 2TB 7200 rpm Seagate
Ram: G.SKILL Ripjaws Z Series 16GB (4 x 4GB)

Please tell me what is the best PSU for this build
Thank You guys.

I suspect you plan to O.C:

PCPartPicker part list / Price breakdown by merchant / Benchmarks

Power Supply: Corsair Professional 1050W 80 PLUS Gold Certified ATX12V / EPS12V Power Supply ($208.98 @ Newegg)
Total: $208.98
(Prices include shipping, taxes, and discounts when available.)

For a system using two GeForce GTX 780 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 850 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 65 Amps or greater and that has at least two 6-pin and two 8-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

Thank you guys for helping.

I honestly think you should get a 1050W PSU to be safe + maximize your overclocking potential.
