The Platinum Series SS-1250XM Active PFC F3 1250W Power Supply Unit from Sea Sonic Electronics is designed for high-performance PCs where reliability is essential. It offers tight voltage regulation (3%), virtually silent operation, and a fully-modular design. The 80 PLUS Platinum efficiency ensures power savings.
The power supply unit employs Hybrid Silent Fan Control, which offers fanless, silent, and cooling modes to balance between silence and cooling. In addition, it uses high-quality conductive polymer aluminum solid capacitors and 221°F (105°C) Japanese aluminum electrolytic capacitors, ensuring stable operation under extreme conditions and extended life.
80 PLUS Platinum efficiency ensures power savings with greater than 92% efficiency at 50% operating load
DC Connector Panel with integrated voltage regulator module (VRM) offers a fully modular design while minimizing voltage drops and impedance - enhances overall performance and reliability
Fully modular cabling provides flexibility and simplifies cable installation and routing
Easy-swap connectors can be unplugged easily, quickly, and safely
