PSU problems?

Hi, I just upgraded to this setup:

AMDX2 5600+
2GB DDR2 800Mhz
Nvidia 8600GTS 256mb
2 sata HDD
1 DVD Drive

I am running this on a 430W Thermaltake PSU; is this PSU enough for the hardware?

I'm asking because programs are freezing on me and I can't start any games;I click on their icon (Stalker & WoW) and can hear the music but as soon as the game loads it crashes to desktop.
I've already tried re-installing drivers & direct x.

Thanks

 

if its the TR2 430W (ive got the same one) then its waaaaaaay underpowered. only 18A on a single 12v rail

 

Yeah, I had the same problem a while ago with that exact same PSU. It is tremendously under powered for your rig. Allow me to recommend the Hiper 580w Type R. It's not only a terrific psu, it's dead sexy.

It's also in black or silver.
