is it quad or single rail actually??*Update: SilverStone tells me that the pontimeter on the left adjusts / fine tunes the +12v voltage to optimize overclocking and system stability. The on/off switch on the right splits the +12v rail from a single rail to quad +12v rails. Although this obviously voids the warranty, it gives overclockers and computer enthusiasts a chance to tweak this power supply.![]()
