Voltage and current are the two important things a power supply usually needs to keep stable.
Power supplies usually take wall current at 110-120 volts and 50-60 hertz and turn it into DC current at a particular voltage like 3, 5, 10, or 12 volts. If the voltage or current isn't stable, whatever is plugged into it could die from not having enough power, get errors from sudden changes, or even burn up.
