GO FOR GOLD Certified 80 PLUS Gold for generating clean and consistent power while reducing heat waste and noise. The PQ-M Series achieves 90% efficiency at 50% system loads. BUILT SOLID Carefully constructed throughout with quality components to ensure pristine power output quality. The modular board is hard connected to the circuit platform instead of traditional cables for added rigidity and less signal noise. SILENCE IS GOLDEN A fine-tuned silent fan curve helps produce a perfect balance between cooling and silence, with an additional fan stop option during low temperature conditions. A rear fan control button also allows the option for setting a minimum fan speed when fanless mode is not preferred. BEST OF THE BEST Fluid Dynamic Bearing (FDB) fans are considered the best-in-class for operating noise and life expectancy compared to other fan bearing types. The hydrodynamic and fluid-based properties greatly reduce friction and vibration that enables better reliability and quiet operation.
