Hi everyone,
I am buying computer for work and I chose this:

-CPU: Intel® Core™ i3-4130
-MB: Gigabyte GA-B85M-D3H
-graphics card: none (integrated) it's for work, so I don't need powerfull graphics
-RAM: 2x4GB Kingston HyperX Beast CL9 1600MHz DDR3
-hard disc: Seagate Barracuda ST1000DM003 1TB , 7200 64MB

I need your help choosing PCU. Can anyone tell me which one of these is the best?

Cooler Master G Series 600W
CHIEFTEC CTG-550C 550W
SEASONIC SS-500ET 500W
CHIEFTEC CTG-500-80P 500W
CHIEFTEC GPA-500S8 500W
CHIEFTEC GPS-600A8 600W

Note: These PCU's both fit in my budget and are available in my country (whic is bigger issue), so please focus on them before recommending some others
