A good 500 - 550 watt PSU will work nicely.

I'm using a Corsair 550VX (41 amp 12 volt rail)

in my Q6600/4870 build.

A 4870 needs about 11 - 12 amps and 2 PCIe power connectors.

i can't buy it here ( i'm outside USA) so can these two that i mention before be any good

The Thermaltake you linked to has passive PFC (little red voltage switch). If the FSP has active PFC (no voltage switch) it would be better. Both should be powerful enough to run your card
