    Default Computer shuts down without warning

    Hi all. Lately while gaming my computer shuts down as if the power cable was pulled. There is no blue screen or any warnings, just powers down immediately. I've only been experiencing this recently. I've built this computer last year and no trouble until now. Nothing is different either. I think the problem may be the PSU? However, I've heard it is a quality one. Thoughts?


    SPECS:

    Antec EarthWatts 380D (Bronze certified)
    Asus CuCore Radeon HD 5770
    AMD Athlon II X3 Rana 445 @ 3.1ghz (4th core unlocked, otherwise stock)
    BIOSTAR A880G+ AM3 AMD 880G HDMI Micro ATX AMD Motherboard
    G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM

    If it just shuts down, as opposed to a reboot, etc., then it most certainly can be the power supply.

    Certainly a system with just a Radeon HD 5770 and X3 processor shouldn't be using that much power, but it does sound like a PSU issue.

    Thanks for replying. I ran prime95 and had hwmonitor open at the same time. If you don't mind I have made a video and managed to reproduce the same issue. At the end of the video the system shutdown so you can skip to the end and look at the stats : http://www.youtube.com/watch?v=kQxvbuESICc

    A shut down is a shut down and 99% of the time, that's a PSU issue. Too bad you don't have a power meter like a Kill-A-Watt to see what your system is drawing. At the very least, another PSU of equal or greater wattage could shed some light on the problem. But right now, I'm sticking with inadequate or faulty PSU.

    I don't have anything like a kill-a-watt thingy unfortunately. Poop... looks like I will have to RMA the PSU! Thanks for your help.
