    Ok, I knew that bit. so I'd have to make cable to go from the 5v output on the LPSU to the green blocks?

    I have been speaking to Ian about his Isolator board. It will fit my Pi3+ and Allo dac but i dont understand how to power it? It doesn't have the Micro USB port so how would it be done?

    The PSU i will be using is this:

    Any help is appreciated.
    Does the PSU have 2 x 5v outputs?

    Thanks for the response just what I was hoping for.

    I was thinking of building my own using an R-core, but at that price it doesn't seem worth the effort.

    What turned you on to this PSU? It looks pretty well built.

    It was recommended to me buy Antonio here. I asked Firebottle his advice and he said it wouldn't give 3A, nearer 2.7/2.5a. That's fine for the pi.

    You will need a cable with a power connector on one end that plugs into the PSU, and wires with bare ends on the other that go into the green terminal block on the isolator board. Make sure that you get + and - the right way round!
    But if you have an Allo DAC why not get the Allo Isolator?

    It's expensive.

    I can't remember what I paid for Ian's Isolator Pi, but I don't think it was a lot less than the $57 that Allo are asking for their Isolator 1.2

    I'll have a look. Unfortunately, all the funds are now allocated for something else now so it will have to wait.
