Help choosing PSUs

My build:

MB: ASUS X99-PRO

CPU: Intel i7 5820k OCed 4.3@1.24V

GPU: Palit JetStream GTX 970 OCed 1523/2000@1.25V

RAM: 16GB DDR4 G.Skill Ripjaws4 2666 CAS16 OCed 3000@1.4V

HDDs: 2 3TB WD Red.

SSD: Corsair Force LX 256GB.



Would a 600W PSU be enough? Or should I aim for 700W? Cause it seems the CPU alone can gobble upwards of 300W, and the GPU is good for another 200W or more.



Out of these PSUs that are available where I live, which one should I get?



SEASONIC S12II 620W 80 Plus Bronze - $75, 5 year warranty.

Zalman GV-700 700W 80 Plus Bronze - $64, 3 year warranty.

Kuroutoshikou KRPW-N700W/88+ - $63, 2 months warranty :lol:.

Cooler Master G750M - $108, 5 year manufacturer warranty.

Cooler Master G650M - $92, 5 year manufacturer warranty.

Cooler Master GXII-750W - $105, 5 year manufacturer warranty.

Cooler Master GXII-650W - $91, 5 year manufacturer warranty.

Cooler Master V650 - $101, 5 year manufacturer warranty.

Corsair CS650 80 Plus Gold - $105, 3 year warranty.

Corsair CX750 V3 80 Plus Bronze - $94, 3 year warranty.

Cooler Master Thunder 700W - $83, 3 year manufacturer warranty.

Zalman Goldrock 650W Single Rail 80 Plus Gold Modular PSU - $111, 5 year manufacturer warranty.



Which one of them is most ideal for my case? Even though my budget allows for all of them, I'd still like to get the most bang/buck cause the leftover will be added towards a beefier CPU HSF (I'm eyeing the True Spirit 140 Power Edition, costs about $55 here plus $15 for a TY-143 fan).



Thanks :D
