To make great power supplies even better, SilverStone engineers delved into the details with the Strider Gold series. In order to reduce the already low noise generated by the Strider Gold, they replaced the fan with SilverStone’s own Air Penetrator , which has superb cooling ability and is equipped with fluid dynamic bearing. This allowed for reprogramming of the fan controller to enable lower fan speed at any given loading condition compared to the predecessor. Various components were also re-tested and replaced with newer versions for minor boost in efficiency and performance. An excellent FF141 fan filter with magnets is even included in the package for use to reduce dust buildup. With the fan and component upgrades, the Strider Gold Evolution series will again encompass wattage range from 750W to 1200W with 80 PLUS Gold level efficiency, ±3% voltage regulation, ±3% ripple & noise, and high amperage single +12V rail as its main features. For discerning users looking to get a top-notch power supply with all features covered and more, this is the perfect solution.
