    Intel quad core 2.8 GHz processor
    Asus P5KPL-AM SE motherboard
    2GB ram

    windows 7 ultimate

    hi,

    the problems started last week when i installed my new graphcis card (stated above) i played crysis 2 for about 30 mins and my pc completely shutdown and i couldn't turn it back on.

    I opened it up and saw that the motherboard light was still on, i sent it into a professional who confirmed my theory of it being a power issue and he changed the power supply.

    The same thing happened the day my pc was returned so I sent it back, he thinks we should up the power to a 850 w supply

    the thing that gets me is that my graphics card recommends 400w or greater, but my original supply was 650w, and the one he replaced was 500w please suggest anything as i am worried the same will happen with this 850w supply

    Thanks in advance :)

    What brand of power supply were you using?

    Not all power supplies are the same and wattage isn't an indicator of quality.

    Not too sure about the first one, but the second one he installed was winpower.

    Winpower is a midline power supply, not the best and not the worse. I believe that 500W is too "light" for your application with a quad core Intel processor and a 550 GTX graphics card

    My guess is the current power supply is becoming stressed and one of the rails is "dropping out" when the power supply heats up.

    This power supply should be adequate for the quad core processor and 550 GTX card..

    If you want to go to a 850W unit to have more reserve power then I would recommend this model.

    Not to get off the subject here.

    The Asus P5KPL-AM SE motherboard supports up to 4 GB of DDR2 PC2-6400(DDR2-800) RAM.

    Why are you hobbling your computer's performance for gaming by using only 2 GB?

    thanks for the quick replies and help guys,

    i'm hoping the 850w one the guy is fitting tomorrow is going to be enough if not i'll probably end up going for your suggestion win2kpro.

    also i've already ordered 4 gb of ram, should be coming tomorrow.

    Post the make and model of the power supply that get's installed. There is a tremendous amount of differences in power supply's rated at the same wattage.
