In the past couple years, the options for someone looking to buy a PC power supply have become much more interesting. Prior to this, power supplies were mostly just plain boxes with a spaghetti-like mess of cables jutting from them. Sure, those are still around and work just fine. But for someone who has spent a lot of time and effort modding a case, putting an ugly, plain box in that case is not a pleasant thought. To the enthusiast and modding community's delight, companies designing power supplies started using fans with LEDs, nicer materials, cable sleeving, and other improvements to spice up the PC's power center.
