Compact 650 W ATX power supply

The Silverstone Strider Gold S unit delivers 650 watts of continuous DC output in a fully modular ATX form factor. Its 140 mm depth makes it one of the shortest full-modular designs available, simplifying cable routing in tight chassis. An 80 PLUS Gold rating confirms high efficiency across typical loads.

Fits small cases and frees cable space

At 150 mm maximum length the supply suits compact builds where longer units would conflict with drive cages or radiators. Full modularity lets you connect only the cables your build requires, reducing clutter and improving airflow. A single +12 V rail with tight 3 % regulation feeds CPU and GPU without multi-rail balancing.

For builders who need short depth

The 120 mm fan runs at a minimum of 18 dBA, keeping acoustic output low in noise-sensitive systems. Continuous 40 °C output rating supports sustained workloads. Buyers who want higher wattage headroom or a larger fan for even lower RPM should look at larger-capacity models in the same series.
