    Wiring a laptop brick to Opus for at-home testing?

    I have an old power brick from my Dell Laptop that is starting to fray around the connector.

    Can someone give me some details regarding how to wire this to my opus-powered carpc, so that I can test and install at home?

    I think that my big question is how to figure out polarity.

    TIA

    Providing it gives ~12V and around 90/150W (7.5A/12.5A) depending on model, then it should work.

    As said, use a multimeter to check polarity, and also output voltage

    Ok. Thanks for the simple answer.

    Any chance you could provide a couple more sentences of step by step for someone who hasn't used a multimeter to any degree before?

    Thx

    No.

    Opus really wants several amps (like up to 10). A Dell brick may supply 3 or so. You will not power a small aubergine with the brick via Opus I've tried using a 5 amp battery charger with an opus, which is more powerful than a Dellbrick, and that hasn't worked.

    Also, aren't Dell power supplies generally 19 volts? Or is it 15? If 15 it may be okay, but I'd still be very surprised if the current was sufficient.

    Thanks. You're right, I think it is 3 or 3.5.

    Any thoughts on a quick/easy/cheap way to power it up at home for a little while for setup?

    Thx

    Use a desktop power supply and wire your opus to that. I use this method to test car audio equipment. (and to power my car fridge in my computer room)

    That, or a 10amp car battery charger. They're a dirty 13.8volt supply, but that's exactly the conditions the the Opus is designed to work under!
