Test of power supply unit -5v not functioning
If you are concerned about the voltages being on the incorrect pins, it is quite alarming. I have not encountered a power supply that adhered to the standard at least. What is more troubling about power supplies is whether they can actually provide the rated power through the connectors. You won't be able to verify this with a simple device that uses LEDs.
Your issue isn't just about a low-cost power supply not delivering the right voltages when no load is connected to a tester; it's about keeping those voltages stable when the power supply is operating under load. I question whether even the most affordable power supplies would have their connectors improperly wired.
