We are pride ourselves in providing the highest level of standards in designing computer enclosures, power supplies, and accessories. Our pursuit for the first class aesthetic appeal is relentless and our devoted team is constantly searching for the best technologies that suit end-users with different needs and will make our products as technologically sound as they are very unique piece and beautiful.As desktop computers continue to advance toward ever more efficient and smaller designs, SilverStone is helping to drive the efficiency movement by releasing the Strider Platinum series of power supplies. Created to be the smallest fully modular ATX power supplies with 80 PLUS Platinum efficiency, they are also incredibly quiet with the ability to run in fanless mode. If the loading condition is below 20%, the fan in the power supply can remain off for silent operation during idle or low powered computing activities. Other great features inherited from previous Strider series include ñ3% regulation, powerful single +12V rail, 24/7 continuous power output, and multiple PCI-E cables. For those looking to build highly efficient systems in small footprints, the Strider Platinum is definitely the best choiceFeaturesCompact design with a depth of 140mm for easy integrationHigh efficiency with 80 PLUS Platinum certification100% modular cables24/7 continuous power output with 40 operating temperatureClass-leading single +12V railStrict ñ3% voltage regulation and low ripple & noiseUltra silent 120mm fan with intelligent semi-fanless operationSpecificationsColor: BlackMax.
