PSU Problems

[kahlos]

Hey
I don't know what wattage I need on my power supply. I have this but

2x 7200RPM HD
2x X850XTPE (well OC'ed X800GTO2's)
1 x Opteron 165 Duel Core processor (uses 110 watts i think)
2 x 1GB stick of OCZ plantinum RAM
1 x Crossfire Mobo
1 x NEC 4400 DVD-R

So how much ruffly do i need. I checked out the caculator
here but its too old. I was thinking summin around 500 - 600 Watts. And what PSU's do you recommend i get ?

i use a 520W PSU and i've got a lot more things. 520 should be enough is my guess.
