Three things can happen when the power supply is insufficient- voltage fluctuations, power surges and spikes.
Can a low level of power damage a component?
This in itself will damage components, not because the current is too low, but because the voltage is too high. I suspect drdeathx has once again (I could be wrong,) evaluated the problem and jumped to the wrong conclusion since multiple things could be going on. The drop in current might be a symptom of the issue, not the issue itself.
How can I tell if my power supply is faulty?
There are also some obvious clues that should lead you to suspect a faulty power supply. These include: One of the simplest tests you can perform on a power supply is to measure the output voltages.
