First of all, I'm currently living in Venezuela so I don't have many choices plus I'm on a tight budget.
I'm trying to choose between EVGA 500B, Thermaltake Smart 700w, and EVGA 750 BQ.
Safe to say that the EVGA 500B is a lot easier for me to get for different reasons.
This is my current system:
-FX 6300 @ 3.8
-GTX 750 1 GB
-8 GB DDR3 RAM
-500GB HDD

Is this all you can choose from? Think that the 500B will be enough for what you have and quality isn't worse than the other options.

Maybe the Corsair CX (new) are available or the Seasonic S12II or even S12III?

Unfortunately these are my best options, I've been looking for a while.
I forgot to mention the price of each psu here.
EVGA 500B (NEW) - $60
Thermaltake Smart 700w (USED for 3 months) - $50
EVGA 750 BQ (USED for 1 month) - $70

All trusted sellers and I can test them before.
