Is my power supply going bad?

I've probably stressed my thermaltake 750w a little more than I should with my Processor OC'd and running SLI 8800 ultras OC'd (using a couple 4 to 8 pin adapters for the second one) so it wouldn't surprise me but anyway.

I got a couple random reboots playing CoD:WaW and then my screen would go blank after going into windows. I could boot in safe mode, but not normally. I took out one of my video cards and was able to boot fine until I overclocked it...I got the blank screen after windows loaded again. Then I booted to safe and uninstalled the drivers and now it's working fine (not overclocked).

Think it's the stress the overclock is putting on my psu that's causing the failures? The 8800 ultra I'm using is relatively new and my factory overclocked one won't work because I get the same blank screen issue I get when overclocking this one.
 
I don't think opteron 175's draw enough power to kill that CPU, even OC'd
I'm fairly sure 2 8800s wouldn't tank it either.

That said I built my pc with a 1kw psu and my next is going to have at least as big.
