yeah, I don't think there will be a problem w/ your rig... you've just been underpowering it. I would highly suggest you get a new psu though. maybe you can get some cash back from the guy who you got it from. for your rig I would suggest a quality 500w psu.

tell him that you have to have at least a 350w psu to run that 6600GT... he can look at the specs and manufacture suggestions and it will back you... then try to get some money out of him.

then get either a Seasonic S12-500, OCZ powerstream 520 or a Sunbeam Nuuo

if you aren't overclocking you should be fine... but thermaltake psus aren't known for there awsome powerness or anythign like that so it may be a bit lacking if/when you do oc
