The Modular Power PSUs from Kolink boast an improved circuit design and an associated performance increase. These features offer a significant enhancement of voltage regulation and meet the needs of modern powerful computers. In addition, the extremely quiet 120mm fan, with a fined-tuned RPM curve, has been optimized for airflow. This makes the Modular Power the quietest power supply of its kind. The Modular Power PSUs looks amazing in any high-end gaming system due to its modern design and the flexible, flat and semi-modular cables use for connections across the system.

The PSU delivers up to 444W and 37A on the +12V rail while providing 100W and 15A each on the +3.3V and +5V rails. This especially high efficiency meets the requirements of 80 Plus Bronze 230V EU and exceeds 85/82/82 percent at 50/20/100 percent load (at 230 Volt input voltage). The PSU\'s highly efficient circuit design features independent DC-to-DC converters for the 3.3V and 5V outputs, ensuring extremely precise voltage regulation. Each example of Modular Power series is cooled by a 120 mm fan with durable and quiet sleeve bearings that offer a fine-tuned RPM curve. Thanks to the optimized airflow, the fan and thus the entire PSU remain quiet as a whisper. Besides the 20+4 pin for the motherboard, the Kolink Modular Power has a 4+4 pin connector for the CPU and two 6+2 pin connectors for dedicated graphics cards. Four SATA and two Molex connectors are available for additional components. The flat, flexible, completely and semi-modular black cables have a modern look and fit into almost any up-to-date gaming setup. Note: For environmental reasons the manufacturer does not supply a power cord for connection to the mains.Technical Details: Dimensions: 150 x 86 x 160 mm (W x H x D)Fan: 120 mm (automatic control)Colour: Black (power supply, fan)Efficiency: minimum 85/82/82 percent at 50/20/100 percent load.
