Help finding the right power supply

[thecandyman0838]

I recently purchased an Asus GTX 1070 dual and I need a power supply for it. My case will only fit a 3.39" x 5.91" x 5.51" psu, and I think a 750W would be nice to have if I decide to upgrade my CPU from an i5 4440 to an i7 in the future. The only 750W power supply I found that would fit is a Corsair CX750 bronze, but I am weary about due to the reviews saying that it doesn't last and it randomly turns off. Do I have any other options, or is this power supply actually good?
