The S12G Series SSR-550RT Active PFC F3 550W Power Supply Unit from Sea Sonic Electronics is designed for midrange PCs where reliability is essential. The unit comes with a 120mm double ball bearing fan that enables a longer life span for the power supply while reducing the noise output and fan rotation speed. It employs Smart & Silent Fan Control (S2FC) system that ensures balance between silence and cooling.
The 80 PLUS Gold-certified power supply ensures up to 90% efficiency and power savings. 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. It is compliant with Intel ATX 12V and EPS 12V standards and supports dual 8-pin PCIe and dual 6-pin PCIe connectors.
