| Cable-end connector counts | Modular cable inventory: 20/24-pin motherboard ×1; EPS/ATX12V 8/4-pin ×1; PCIe 8/6-pin ×1 plus PCIe 6-pin ×1; SATA ×3; Molex ×2; floppy ×1. Check the exact supplied cable revision. |
| Revision and cable cautions | Follow 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.
