"When gamers and overclockers like myself start adding more and more video cards, hard drives, fans, and pumps and when we push these components even harder to the point of breaking by overclocking them, the need of a high out put, highly efficient power supply becomes necessary.

Which brings us to another point, what type of PSU to get? We already know we need a PSU that is powerful, but what kind? Do we need a single rail PSU? Or do we go multi railed? Boy, this really helps us narrow things down (sarcasm). Well, why not get a power supply that can do both? SilverStone, a name we overclockers trust and know for having one of the top of the line power supplies in the market, brings us a PSU that can be switched from multi railed to single rail by a flick of the switch."
