First of all, it is hard to recommend wattage without knowing what GPU you will be using.
Second of all, both of those PSUs are overrated crap. A modern PSU has full range active PFC (no little voltage switch), and 80+ certification. Antec, Seasonic, Corsair, Enermax, and XFX are among the better brands.
Once you know what GPU you'll be using, go here: http://www.extreme.outervision.com/psucalculatorlite.js... for an estimate of PSU size. I'd add 50W-100W just for a little more headroom, but if you choose a quality model, you'll be okay.

Crap! Missed the GPU, I edited the first post.

Well there's no much to chose here (Panama), plus there's only one hardware store here.
Here's the full list of their stock

Disponible (green): in stock
Disponibilidad baja (yellow): low stock
Por pedid (orange): sold out

Also right now I can only afford ~$100 for the PSU, maybe you guys can recommend me the best of the worst ones. :sarcastic: 

Again, thank you :)

In that price range, they all look pretty dismal. Perhaps you can find an online vendor who will ship to Panama. Will ZipZoomFly or TigerDirect?
