Depends on your OS

By cutting power, your Windows machine may be in an undesireable state at that moment, for example writing a file (even if you don't know it), and you can cause it harm. In newer machines, where you ahve to hold the power button for it to shut down, the CPU knows enough to abort all operations, so there is a reduced chance of problems, but that is very far from zero.

On the other hand, that's the only way to shut down a computer running DOS.
