    I'm building a PC and I've gotten everything plugged in (correctly?).

    When I flip the switch on my PSU, the lights on my motherboard light up. At this point, my case power switch does not do anything.
    My front panel connectors are all connected correctly (Power SW / Reset SW / HDD LED)

    My case does feature a LED control board that connects to the 4-pin cabel labeled "POWER".

    I've connected my PSU to the rear of this 4-pin POWER cable and connected an adapter to the front of the POWER cable. I do not know where the adapter end plugs in though.

    If the adapter was supplied with the case/controller, then I would suspect it connects to the control board.

    The case and case model info would be helpful.


    Having said that, the LED controller not having power shouldn't affect the PC from powering on.

    ________UPDATE_______
    I've gotten the motherboard to receive power, and the case starts up including fans and lighting. Every single fan is working.

    When plugged into my moniter while powered on, the monitmo receives no input at all.

    I've tried both HDMI and DisplayPort

    Unplug the GPU and connect to the on mobo connectors and try that.

    Remove the GPU first. The presence of the GPU will sometimes disable the on mobo graphics.

    The Ryzen 7 2700 doesn't have graphics.

    Have you read the guide at the top of the hardware forum for problem builds? If not, do so. If you follow ALL of the steps, you will find the cause of your problem.
    Common errors for new builders;
    1 Motherboard shorting to case due to incorrect placement of standoffs
    2 4/8/12pin aux pw connector not plugged in
    3 Ram not fully seated in slot or slots
    4 ATX or Aux pw connectors not fully seated
    5 Parts not compatible. Does not seem to be an issue here
    6 Cooler or HSF not installed correctly. This is more an intel problem than an amd problem since the amd type coolers are pretty much idiot proof
