There was a calculator somewhere on the internet where u just chose ur parts and then it told u how big PSU u need. Ofcourse it ain't that accurate.
Those calulators are so crappy. they are usally of by at least 50-80watts.

it should be enough but everything points to it not being enough.
try taking some other stuff(second HDD,second CD drive..) out and leaving all the memory in so less Watts in used by other things. that way you will know if it is a PSU problem.
