Budget PSU for PC

[zouvu01]

Looking for a budget PSU in my country, I'm between these options:

EVGA 600W

Cooler Master MWE White 550W

Gigabyte GP-PB500W

EVGA 450BT

EVGA 450 GD

Riotoro Builder Edition 500W

I don't know anything about PSU's, they have similar prices in my country. I just want to pick the best I can for the price.

Could you post a link to the online vendor page where you could get them so we could take a look at the options.
Also include your budget for the PSU and system components.
