When you're building one of the best gaming PCs, the first thing that you're thinking about is what graphics card or processor you're going to build your entire rig around. However, while they might not be as sexy, the best power supplies are extremely important to your gaming PC. Because while they might not be the driving factor behind a higher frame rate, these little bricks supply the power to everything else in your system.

All PSUs (power supply units) aren't created equal, however. There are actually a lot of power supplies out there that'll do more harm than good, either by delivering power inefficiently or by cutting corners and becoming fire hazards.
