Overview
The Fortron SPI-250G 250W power supply is an AT form factor unit designed for legacy and industrial PC systems. Manufactured by FSP Group (formerly Sparkle Power International), this model delivers a continuous 250W output and accepts universal dual-voltage AC input (90–264V, 47–63 Hz). The SPI-250G supports both 115V and 230V configurations, making it suitable for global deployment in retrofit and replacement applications.
Key Features
- AT form factor chassis compatible with standard ATX enclosures
- 8cm rear-mounted cooling fan for reliable thermal management
- Dual-voltage input: 115/230V AC with independent current ratings (10A @ 115V, 5A @ 230V)
- Dedicated monitor outlet for powering external displays via C14 AC inlet
- -5V rail for industrial and legacy motherboard compatibility
- 5A fuse protection at 250V
