Thanks bro but i will go with the Corsair 650TX i read some reviews and it is good for a single and in the future for 2 cards. it costs a little more here in greece (99 euro) but it is the best i can get for that money here.
The SS 650HT reccomended by mosox
is an upgraded TX650 without the Corsair labels, paint or cable sleeving.
It does come with all 4 of the pcie power connectors needed for Xfire 6870's and a higher efficiency rating for less money.
