    Hi, my mac pro does a Improper shutdown on games and shutdown on sleep mode. I have made all the reset (PRAM and SMC). I run on OS10.6.5. I have tried two different video cards (8800GT and HD 4870) same crash here. The apple hardware test find nothing. So now I'm thinking that it's probably the power supply.

    Anyone have a idea to help me find out.

    Thx

    Does the machine crash or KP while you are using it? I don't see anything in your log snippet that would explain an improper shutdown. PSU could be the cause of a random shutdown.

    Yes it crash like if I disconnect the power. It's not random crash, it's when the video card work harder. By the way it's the same thing in bootcamp win 7 when I play games...

    You didn't happen to notice your temp when it crashed, did you? Try smcfancontrol. Crank up your fans to cool it better and see what happens.

    Yes I already done the SMC blast. All my temps seem to be good. The highest one is the north bridge at 65oC...

    Since it occurs with different video cards then sounds like the power supply is the problem.

    One other thought. Is your Mac pro using a UPS or are you plugged in to the wall socket? One thing about the Mac pro is it will shut down if it detects low power similar to a brown out or on a particular breaker that drops low due to many things running on it. If your plugged into the wall, move it to a different outlet and see if still does it.
