    I would just go with an inverter. It'll give you lots of power and be real cheap.

    Sorry, you need to go to mp3boat.com and ask over there!

    I would just go inverter as god_of_cpu says. 400-500W would be enough. you can then buy a nice decent ATX PSU. Nice and cheap. Maybe get a more powerful ones as it is likely anything else added will run off mains adapters.

    i dont know that much about what he has on the boat
    i know it has inverters to run mains equipment but i think he wants 12v stuff when he can so save on power i suppose

    i know he has a 12v tft monitor so wants to have a 12v pc this is basically going to be a ott mp3 player

    i did have a 250w power supply in it before with a cd/rw and 5 hard drives (dont ask) and it worked fine so i was thinking i would only need a 100 -150w psu
    for just the board and 1 hdd

    What about one of those keypower or summit? don't they do a 200 or 250W ATX style 12V psu?

    just noticed its not a p4 but a celeron 2ghz
    how much difference does this make to the required power supply

    btw its all fitting into a 24port network hub chassis so height is an issue
    think i will end up using a normal 250w 1u rackmount psu
    if i like it or not

    Considering you want to run the diesel engine as little as possible on a narrow boat you want the power to be as efficient as possible. Hence you need a DC-DC solution. An inverter would put too much draw on the batteries.

    I would NOT recommend the PW-200 as the 12V to the PC components will be unregulated....unless you get a Carnetix regulator. This combination would be pretty good.

    Your other option would be a 150W Opus. The advantage would be that the low-voltage protection would stop it draining the boats battery supply too much.
