600W or 750W for my setup?

Hey, guys.



I'm building a PC and I want to know whether I should get a 600W or a 750W power supply. Here are the expected components:



Graphics: SLI 2x EVGA GeForce GTX 960 SuperSC ACX 2.0

Processor: Intel Core i5-4690K Processor 3.5 GHz

Motherboard: MSI ATX DDR3 2400 LGA 1150 Motherboard

RAM: Corsair Vengeance 16GB (2x8GB) DDR3 1600 MHz

HDD: WD Black 1TB HDD: 3.5-inch, SATA 6 Gb/s, 7200 RPM

SSD: Maybe or maybe not any 240-250GB one (recommendation please)



Which of the following power supply should I get:

Corsair Builder Series CX 600 Watt ATX/EPS 80 PLUS

Corsair CX Series 750 Watt ATX/EPS Modular 80 PLUS Bronze



Since I'm on a budget, I'd also like to know if the following motherboard is any different from the one I mentioned above:

MSI Computer Corp. Motherboard ATX DDR3 1333 LGA 1150 Motherboard



Thanks.
