    psu run in parallel?

    i was searching for a way to converter a standard 120vac psu into a 12vdc input but it seems like more of a challenge than i thought but in my searching i came across a suggestion of possibly running 2 or more psu's in parallel to get the wattage out put i need.

    Now is this possible or am i limited to using a start up/ shutdown controller with a power inverter.

    Either way ill make it work i just want to know the best route to take.

    Why are you not using a dc-dc solution. They are so cheap nowadays, it is really a no brainer.

    No to parallel supplies.

    But with 250W supplies available, what's your problem?

    he is trying to figure out how to run a xbox360 without a inverter
    Powering Xbox360

    the adapter cable he was looking at in that thread requires a power supply capable of 16.5 amps on the 12v line, and 1 amp on the 5v line..

    Ah - big consumers....

    Why not convert its SMPS to DC as was done elsewhere (another (old?) mp3car thread?)?
    (Though I'd probably rather stay standard and use an inverter.)

    5V/1A is no problem, but 12V/16A (regulated) - that's a fat choke on a 60A MOSFETed $5 power chip.

    I just get an inverter and be done with it. If you want to avoid some of the issues, get a true sine wave inverter
