    WTB: 13.8VDC@10A power supply for Opus

    I am looking to buy a 13.8 VDC @ 10A power supply to power my Shuttle X, now that I installed an Opus SFX-1215 150 watt PS in. Someday I may want to check out the puter while I'm in doors. Radio Shack has one for $79.99 but I'm looking for a cheaper one if it can be done. Anyone have one for cheap or knows of a place to get one? They are rather heavy so shipping may be expensive so maybe Radio shack is not so bad???? Anyone have a cheaper solution?
    Thanx,
    Gary

    How about using a standard 350W ATX PSU ? I use one to power my inverter when I am using the carputer indoors. Just remember to ground pin 14 (PS_ON green wire) to turn on the power supply. Some ATX PSUs need an external load on +5V to regulate. If the +12V rail is not 12V +/- 5%, you may need to connect an old hard disk to present a dummy load on the +5V rail.

    I knew someone would have a good solution.
