Silverstone Technology Strider Platinum 550W ATX Power Supply

Compact Platinum ATX Power Supply

The SilverStone Strider Platinum 550W is a fully modular ATX unit built for small-footprint systems that demand high efficiency. Its 140mm depth allows installation in tight chassis where longer power supplies would not fit. The single +12V rail delivers 550W of continuous power at up to 40°C operating temperature. Builders who need more wattage for multi-GPU configurations will have to look elsewhere.

80 PLUS Platinum Efficiency and Semi-Fanless Cooling

The 80 PLUS Platinum rating means the unit wastes less energy as heat during normal loads. A 120mm fan runs only when the load exceeds 20%, staying completely off during idle or light work for silent operation. Under load the fan speed scales with temperature to keep noise low. Strict 3% voltage regulation and low ripple protect sensitive components.

Fully Modular Cabling for Clean Builds

All cables detach so only the required leads occupy space inside the case, improving airflow and cable routing in compact enclosures. The package includes multiple PCI-E connectors for modern graphics cards. The ATX form factor fits standard mounting points, and the 140mm depth leaves room behind the motherboard tray for cable management.
