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 and flat cables use for connections across the system.The Kolink Modular Power 850W power supply at a glance:840W and 70A on a 12V rail80 PLUS bronze certificate for high efficiencyATX form factor with a length of 160 mmModern look with flat black cablesConnectors: 1x 24-pin, 1x 4+4-pin, 4x 6+2-pin, 8x SATA, 4x Molex & 1 x S4PKolink Modular Power: Full performance and high efficiencyThe 850 Watt model of the Modular Power series offered here has enough connections and performance for fast gaming PCs with basic equipment. The PSU delivers up to 840W and 70A on the +12V rail while providing 130W and 20A 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 120mm fan with durable and quiet hydraulic 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 four 6+2 pin connectors for dedicated graphics cards. Eight SATA and four Molex connectors are available for additional components. The flat, flexible and completely 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.Specification:Dimensions: 150 x 86 x 160mm (W x H x D)Fan: 120mm (automatic control)Colour: Black (power supply, fan)Efficiency: minimum 85/82/82 percent at 50/20/100 percent load.
