Hi 650w is more than enough, 500 - 550w of a quality psu would be enough.

However, the psu you selected is of poor quality.

GX-650 650 Failed efficiency rating. Failed load testing. Medicore voltage regulation. Poor DC output quality on 3.3V rails. Outdated design. Hard OCP

Where are you looking for your PSU's? Are these from a store or online (and what country)?

Reason I am asking is because I couldn't even find that brand of PSU on Newegg.com.

I would instead look at PSU from a more recognizable company. Also, what is your budget? Try searching for a PSU that is at least "80 PLUS" rated, but preferably at least "80 PLUS Bronze". There are a few (bronze ones) on Newegg.com for $68-$80 before any rebates, taxes, or shipping is applied.

Hi again - tot sys power draw with two 660's will run about 440w, so I would say
550w would be the min & you might want to go a little higher, maybe even the 650w
you mentioned earlier except a decent brand.

what's your budget? need to know so I can recommend

don't know your budget but these are quality units:
