One thing that is common to all computers is power. Whether it is a PC or a Mac, running an almost infinitesimal selection of hardware, it still needs power. With that in mind we should consider the quality of power we are feeding our machines. Weak or budget power-supplies can cause many problems including instability and even hardware damage. It is always a smart idea to spend the little more and purchase a high quality power-supply rather than save a few dollars and get a budget one. Otherwise, this usually ends up coming back to haunt you down the road.
