    I recently put together the c beam model and the 24v power supply is not turning on. I've set it to 115v, and I can't see any issues with the wiring. The power button lights up, but nothing else comes on (fan, power light...etc). Any idea what might be wrong

    So the fan on the controller and power supply don’t need to run?

    PSU fan is temperature controlled. Have read through the datasheet, Fan is on page 2, about halfway https://www.meanwell.com/Upload/PDF/LRS-350/LRS-350-SPEC.PDF
    Controller (assuming its a BlackBox) should have the fan on all the time. Post pictures of your wiring for review

    Thanks, the photos are vague, the Fan has blue LEDs as well, so hard to see with the angles provided.

    Further investigation into pictures: Power switch is in OFF position

    Note you also have this issue reported in duplicate via store support: Ticket 68021
    Lets avoid duplication and continue the discussion via the store support. Thanks

    Just a thought: Probably the camera angle but it looks like both wires are connected to V+
    (If not, it looks like they are connected the wrong way around!)

    No the V+ notation is to line up with PSU terminals, the board itself has a terminal on it .

    See docs:powercase-v1.9:start [OpenBuilds Documentation] and then wired as docs:blackbox-x32:connect-psu [OpenBuilds Documentation] off the pluggable terminals

    Has black / GND on the left so looks fine now (unless it was reversed earlier and corrected before picture was taken)
