I was reading around, and found this website amongst Google.

I am still leaning that I do need more power, even if its just an 850w PSU. However, I do plan on upgrading to another 5800 GFX card.

From what Ive read it doesnt seem to be anything wrong with your PSU, seems to me the overclock is unstable. Did you notice any difference running at stock speeds?
