Sesdave, Scaramonga, thanks for your answers.

Actually, most of the reviews I read about PSU's and PC power consumption say that a good 550w PSU is really enough. So... I'm a bit disappointed. Also, I'm not running an SLI configuration, and the errors I'm getting are showing up at moments where the entire PC isn't stressed (no gfx card load, cpu not loaded that much, etc).


As for the memory, I ran Memtest 1.70 over night, it did 22 full passes without erroring at all, so I guess my memory isn't responsible.
