As desktop computers become more efficient and smaller, SilverStone supports the trend towards even greater efficiency with its Strider Platinum series power supplies. As the smallest fully modular ATX power supplies with 80 PLUS Platinum efficiency, they are also extremely quiet and can operate in fanless mode. If the load is below 20%, the fan in the power supply can remain off for silent operation during inactivity or light computing activities. Other great features carried over from previous Strider series include a regulation of ±3%, a powerful single +12V rail, continuous 24/7 power output, and multiple PCI-E cables. For those looking to build highly efficient systems with a small footprint, the Strider Platinum is the perfect choice.
