    multiple power supplies?

    Rank neewbie here, so please be gentle with me.

    It seems that the cost of a good sized (250 watt, say) DC-DC power supply is quite high, when they can be found at all. Why can't I just use (3) 90 watt units in series (or is that parallel?) to get 270 watts?

    Thanks,

    WSDave

    Scouse,
    I did a search for dual psu and found a number of threads (including one by you concerning using 2 psu seperately to power different items), but I haven't found an answer that I can understand about using multiples to boost the overall output wattage.

    Suggestions?

    Thanks,

    WSDave

    It would seem to me that multiple PSUs in parallel would work. But IANAEE, and I've never seen it done anywhere...

    You didn't search Google, didja?

    Mushin,

    Stupid me!! I searched here, thinking someone might have thought of this before.

    I'll follow your link.

    Thanks.

    Most of those DC-DC PSU available are very week on 12V rail. Technically you can do it because that is how the Mastero/Sproggy MK4.5 is built: 2 separate 12V rail running in parallel @ 5A each. One for mobo 12V stuff and the other for HD and DVD ROM.

    You are right, you will find plenty of thread about any problem you can think of. The problem is, theres never an answer. In the end you learn more about prostrate gland and everything in between whatever scouse throws in the thread.

    That's probably just a bit overstated. There are a great many answers on these forums -- some to questions that were never asked.
