To meet the requirements of current and future desktop computers, SilverStone created the Strider Gold S series power supplies. The Strider Gold S models are all new designs engineered to be the smallest, full-modular ATX power supplies at any Wattage levels.

The Strider Gold S series includes wattage range from 550W to 1500W for a great variety of applications. With short depth designs, all models in the series are among the world's smallest full-modular ATX PSUs. In addition to 80 PLUS Gold level efficiency, the Strider Gold S PSUs are built to meet very high standards in electrical performance with ±3% voltage regulation, ±3% ripple & noise, and high amperage single +12V rail. Other notable features included are 24/7 104°F (40°C) continuous output capability, low-noise fan, and multiple sets of PCI-E cables. For users looking for a power supply with faultless combination of compact size, performance, efficiency, and quality, the Strider Gold S Series is the only choice.
