Is XFX XTR 650W Modular 80 Plus Gold enough?

[AndreVieira]

I'm going with this build:

Intel Core I7 5820k
Asrock X99 Xtreme 4
Gigabyte Geforce Gtx 980 Ti Windforce G1 6GB GDDR5
G.Skill 32GB 2400Mhz Ripjaws V CL15 (4x8GB) DDR4
Samsung Series 850 Evo Ultraslim 500GB
Samsung Series 850 Evo Ultraslim 120GB
2x Western Digital Caviar Blue 1TB (Raid 0)
Fractal Design Refine R5
Noctua NH-D14

PCPartPicker gives me 550w, and i'm not planning to overclock much...

That will be fine. You have a 140W CPU, and a 250W TDP GPU. The rest won't use much. 650W is the right amount for that, with a bit of overclocking. The XFX is also a great PSU.
