I'm going to build my first PC next summer and everything's going fine except I don't know how much power my system is going to need. So after watching some videos, looking for PSU calculators and tearing my hair off, I've decided to ask help from you guys. This is my build:

Motherboard: Asus Sabertooth Z97 Mark 2
Processor: Intel Core i7- 4790K
Videocard: EVGA GeForce GTX 980 Superclocked ACX 2.0 4gb
RAM: Corsair Vengeance 8gb ddr3 1866MHz
SSD: Crucial M550 256gb
Hard Drive: WD 1Tb 7200 RPM 64MB Cache
Optical Drive: DVD-RW
CPU Cooler: Noctua NH- U12 S
Case Fans: 4x 140mm and 5x 120mm high performance fans

I'm not going to overclock anything nor add anything in this system later. I'm leaning towards 750W PSU but I want to know if 650W is enough...

Thank you for helping and sorry for my bad english :D
