The power requirements of enthusiast and gaming PCs have increased dramatically over the last few years, due to the development of ever more powerful and sophisticated CPUs and graphics processors. During this time, the computer power supply unit has risen in stature from being an anonymous, unimportant component choice to become one of the most fundamentally important components in any modern PC.

While the general trend has been higher energy consumption, there are many consumers that don’t need a high end kilowatt power supply. There is a considerable market for mid-range units to power a single graphics card setup, somewhere around 600W to 650W of power.
