    150w PC 300w Power inverter... help?? Please..

    Hi.
    I have a dell Optiplex pc (600mhz P3)
    It has a 150w PSU in it and it is all ready to go in my car.

    I am aiming to power it of a 300w inverter, as it seemed more than enough considering the PSU is only 150w.

    I have plugged the pc in and the inverter. When i turn the inverter on i get a continuous clicking noise from the inverter and the PSU in the PC.
    The PC will not power up and it will keep clicking until i turn the inverter off or unplug the power cable from the pc.

    The inverter does work as i have used it to power household sub speaker to test it with.

    Has anyone got any ideas on what the problem is??

    Thanks

    Chris

    does the dell power up in your house.. I know it's an obvious question..

    if it does.. then it's quite simple. it's an issue with the inverter.. 300W should be good enough .. I ran a full PC of of 300W once.. 15" screen and all .. of course you had to turn on the PC first.. wait a minute and then turn on the screen.. much like they had to do in apollo 13 :-)..

    anyway .. I recommend dc-dc anyway.. you get nice shutdown controllers and battery rundown protection ..

    yeh, the pc powers up in the house, used it to install all software and stuff.

    But it confused me a little because the inverter has powered other equipment.

    I cant really afford the DC to DC stuff, was trying to do it on the cheap.

    But if the inverter has to be sent back then i mite as well.

    How much is the DC to DC stuff?

    Thanks
