    Hello,
    Open builds lead 1515. I just finished a project last night without issue. Went to start another tonight and power supply light flashed on when I powered up but won't stay lit (or hold power). Is there a way to test the power supply? I already ordered the box but it won't be here until next week and I have a deadline this weekend

    The PSU can be entering Protection mode from a short circuit somewhere. Test with ONLY the PSU itself, nothing else connected and see if it stays on? If it does, you have a short in your wiring somewhere
