The PQ-M Series PSU, which reflects DeepCool's assurance that it would create a trustworthy and reliable power supply, is a representation of DeepCool's dedication to quality improvement and higher standards. By offering a solid and reliable basis, DeepCool aids in the creation of better systems today that will meet the needs of tomorrow. It is meticulously made from premium materials throughout to provide flawless power output quality. For increased stability and reduced signal noise, the modular board is hard-wired to the circuit platform rather than using ordinary wires. The correct mix of cooling and quietness is achieved with the help of a silent fan curve that has been fine-tuned, and a second fan stop option is available in low-temperature settings. A rear fan control button allows you to establish a minimum fan speed if you don't want to use the fanless mode. When compared to other fan-bearing types, Fluid Dynamic Bearing (FDB) fans are rated as the best in class for operational noise and lifespan. Improved reliability and silent operation are made possible by the hydrodynamic and fluid-based properties, which significantly minimize friction and vibration. A 10-year guarantee is included with the DeepCool PQ850M 80 PLUS Gold Modular Power Supply. ..
