Will my Corsair AX1500i PSU be enough for my systems?

Admirable
Hi, I would like to know if my PSU will be enough for the systems I'm going to build, or rather rebuild. I'm planning to get some new parts soon. All of my components are:

Intel i7 5930k CPU
Asus Rampage V Extreme motherboard
Radeon R9 295x2 GPUs (2)
Gskill Ripjaws 4 32GB 3000MHz RAM
Samsung 850 Pro 1TB SSD
WD Black 2TB HDD
Cooler Master Nepton 280L liquid cooling with Quad fans
NZXT Phantom 820 case
Corsair AX1500i PSU

Fans:
4x Cooler Master Jetflo 120m
2x Cooler Master Megaflow 200mm
1x Cooler Master CM Essentials 140mm
2x 120mm from the GPU's liquid cooling

I still haven't chosen which optical drive yet, but it shouldn't use that much power, I hardly use it anyways. So is this PSU powerful enough to power all of these? And please give me a straight answer, I know some of the parts are unnecessary and some of the fans are not as efficient as others out there, but I like having some style to my pc rather than just purely performance. Also, I'm not really not if I should switch my operating system too, I have been using Windows 7 Ultimate, if anyone can suggest one that is easy to use and with the least problems, that would be helpful, or perhaps staying with this one. Furthermore, if anyone see anything that isn't compatible with each other, please do tell. So any feedback would be appreciated, thank you.
