That's what I thought to until I tested 4 different adapters.. different brands.. batches.. same voltage and same amperage, etc. As for rewiring i could, but It's all pretty much a singular board with 2 outlets to power switch side of board and 1 for power to fan so it would defeat the purpose of my...

Thanks everyone. I did do some voltage checks and 1-by-1 peripheral comparisons. Only saw a voltage issue when data is pushed/pulled via ethernet (i.e. transferring files to and from the pi). Verified a slight uptick in amperage (i.e going 5V 6A or 5.1V 6A) would mitigate this with the current custo...
