Building new gaming PC, how many watts should I have for PSU?

[411Please]

Here's my hardware: Corsair Air 540 PC Case, MSI Computer DIMM LGA 2011-3 X99A XPOWER GAMING TITANIUM Motherboards , Intel i7-6850k CPU, Corsair H115i PSU Cooler, Corsair Dominator Platinum Series 32GB DDR4 DRAM 2800MHz C16 Memory Kit, Corsair Dominator Platinum LigtBar Kit, Samsung 960 Pro 1 TB M.2 SSD, Samsung 940 Pro 512 GB SSD, PCIe Sound Blaster X-Fi Titanium Fatality Champion Series Sound Card (model # SB0886), Nvidia Titan X (Pascal) with future 2-way SLI, ASUS Computer International Direct Blu-Ray Writer BW-16D1HT Optical Drive, Corsair Air Series AF120 LED Quiet Edition High Airflow Fan - White (x3), Corsair Corsair Air Series AF140 LED Quiet Edition High Airflow Fan - White (x1), and Tingkam Full Kit RGB 5050 SMD 2pcs 18leds 30cm LED Strip Light Attached to Your PC Case via Magnet with 24 key Remote Controller for Desktop Computer Mid Tower Case. And finally the PSU. If anybody can help me with this question, I can finally order my parts which are all listed in Amazon. Except for the sound card, that's from previous build, and Nvidia Titan X (Pascal) which I currently have. Still with all parts I have no clue for wattage. HELP ME PLEASE!

I would recommand this, also its about the build quality and voltage stability, wattage is meaningless.

is there a better quality psu than this? no theres not(that i know).

Thanks for your input guys, sorry I took so long. I found the PSU calculation calculator and went for the EVGA 1200 PSU. I know overkill, but that's this build really and I do plan hopefully for beefing up in the future. Man its really hard to choose a part when you google reviews and read the negatives. I guess ya have to just choose, and hope for the best. Thanks again.
