- Smart Fan Control: The 120 mm fan operates quietly under light loads and increases appropriately under heavy loads.
- Wide Input Range: Supports 100–240 VAC, making it compatible worldwide.
- Advanced Protections: Built-in OVP (over-voltage), OCP (over-current), SCP (short-circuit), OTP (over-temperature), OPP (over-power), UVP (under-voltage).
- Compact Dimensions: 150 × 140 × 86 mm (L × W × H) — fits most standard mid and full towers. :contentReference[oaicite:0]{index=0}
Performance & Reliability
The SG-850 uses high-quality internal components and a solid design to ensure longevity and stable delivery. It has a Mean Time Between Failures (MTBF) rating exceeding 100,000 hours. :contentReference[oaicite:1]{index=1}
Under real-world loads, it maintains high efficiency across load ranges (especially in the 20–80 % range) and keeps voltages rock-solid thanks to single +12V rail topology. Its protections guard both the PSU and your components against unpredictable electrical issues.
Use Cases & System Compatibility
This PSU suits gaming rigs with high-end GPUs, multi-drive storage systems, overclocked processors, and future expansions. Its modular cabling helps manage buildup in compact cases or showcase builds. The wide input range and robust protections make it safe to use in varied power environments.
