@inari @TechConnectify A power supply capable of, say, 100 amps isn't going to shove 100 amps through any load you plop across it.

The actual load put upon the power supply depends upon the supply's voltage and the equivalent series resistance of the load.

So long as that load doesn't exceed the ampacity or thermal dissipation potential of any conductors or components in the circuit, then it's all good.
