Just wondering any psu for this, the only choices I have are

CM, Acteck, corsair (cx) thermaltake (620 watts)
I know they are probably worst than other but thats what I have... Suggestions?

The 600 is bronze the 750 is silver, wich one would you prefer? For a single r9 280x I don't think about xfire for a few years, if I do it I'll buy another psu, don't you think?
