i7 and Corsair 450w

[devjt2]

I'm building a new machine and came across this power supply calculator.

From that information, I bought a Corsair 450w power supply (33A on 12V rail). To run the following rig.

i7 930
Asus P6T SE
12 GB Corsair DDR3 1600
DVD-RW
2 Hard Drives
Radeon 4770 (or Nvidia 9800GT)

I have no intention of overclocking. I'll mostly be doing motion graphics and video editing. Perhaps the occasional game.

System would blue-screen and reboot when playing a game, or rarely when playing video. Sent the video card back suspecting that it was the culprit. Tested the memory with memtest 86+, no errors.

Is it possible that I have under-powered this system?

No, your 40W Unit should be more than fine with that.

Should be more than enough power.

What's the bccode for the blue screen? Usually it can tell whether it might hardware or software related. A Corsair 450W should be good enough for this system.
