  2. Did you turn on the toggle switch on the power supply?
    Did you connect the front panel power switch? And use it?
    Did you use standoffs when you mounted the motherboard in the case?

    Pin 13 i believe (usually only green wire) on the 20+4P (24-pin) connector signals the PSU to turn on. It gets its power to send to the PSU from the motherboard which creates it when the power button is pressed and connected to a separate plug on the motherboard.

    https://www.neweggbusiness.com/smartbuyer/components/how-to-troubleshoot-a-pc-power-supply/ has a pretty good write up on checking no power.

    NOTE:
    Do not not leave the PSU on too long with no load if doing the paper clip test.

    Some motherboards will not power on if the CPU is not inserted and may require separate plug to power them.

    Some power supplies indicators do not light until the are powered on by the CPU, some light all the time when turned on by the switch on the PSU.
