Revision and cable cautionsFollow the ST45SF-G V1 manual only where it matches the unit label. This Gold model is distinct from ST45SF; do not presume its modular leads fit other SilverStone units.

Compatibility & safe installation

  • Check exact case mounting and the SFX length; assess cable bend room and the mounting bracket orientation.
  • At 450 W and 444 W on +12 V, this older connector mix is not a default fit for modern high-power GPU systems. Match GPU connectors and load requirements before use.
  • Never interchange modular cables by brand or appearance; PSU-side pinouts are model-specific.
  • Disconnect from mains for external inspection and never open or probe the assembly.
