My current config is

Sempron
1 gig of ram
MSI 890FXA-GD70
Cosair TX 650
2x 5850 extreme...

I know it's working on the current setup... but if i want to buy a 5830 or 5870 to expand then what are my options for power supply? I'm probably going to fit max 4 cards... so either 2x 5830 or 2x 5870 or 1x 5830 or 1x5870...

If I want to buy another PSU... how much/little power do i need?

2x 5870 is going to add 360w(30a@12v) to your power requirements if you were to have four of them you would need 720w (60a@12v) for the video cards alone.

For simplicity sake i would advise getting a 1kw single rail psu
