    opus power supplies?

    What is the difference between OPUS 90-watt DC-DC Power Supply and
    OPUS 150 watt DC-DC power Supply
    besides the watage, the pictures look very different or is the 150watt just in a metal case making it look alot different?

    They just look different, I don't know why they were designed that way. They are the same other then the obvious wattage difference and also some of the jumper selectable settings are different.

    150watt OPUS has a fan and the 90watt doesn't. At least on my friends 150.

    150w = A * 12v
    A = ~14 amps
    90w = A * 12v
    A = ~8 amps
    A car battery is somewhere in the range of 250 cold cranking amps. That gets larger depending on engine size. Assuming 250 amps, you have 2500w of power to mess with. I would only worry about a second battery/larger battery when approaching this amount with an aftermarket system.

    if you draw more power than your alternator outputs you will end up draining your battery, i know my alternator only puts out 60-70A (yes its crap) and some of its gonna get used by the car so 2500w is somewhat unrealistic
