The SilentStorm Cool Zero is a power supply unit certified with 80 PLUS Gold. It is equipped with modern LLC resonant converter technology and only with quality Japanese capacitors rated to 105°C. The fully modular assembly guarantees a tidy installation and appearance. The optional fan delay mode and Zero RPM mode ensure an optimal and highly adaptable cooling operation depending on the installation position. 80 PLUS Gold Certified. The SilentStorm Cool Zero is certified with 80 PLUS Gold, achieving at least 90% efficiency at 50 % load as well as 87 % efficiency at 20 % and 100 % load. Quality Components. The exclusive use of Japanese capacitors rated to 105°C and a 135 mm fan with a fluid dynamic bearing provide a quiet and reliable operation with an average life cycle of over 100,000 hours. Adjustable Cooling. In the fan delay mode, the power supply fan can, if required, continue to run for 60 seconds after shutdown to ensure a complete cooling of the system. In addition, with the Zero RPM mode, the fan rotation can be stopped at low to moderate loads, thus enabling a noise free operation. Ultra-Stable Voltage Regulation. With modern LLC resonant converter technology, the power supply unit provides a constant and reliable voltage with minimum noise and heat levels. Fully Modular and RYZEN Compatible. Via a total of two 4+4-pin CPU connectors, modern AMD RYZEN systems can be powered without the need for an adapter. Equipped with all Safety Features. Over current and over voltage protection, under voltage protection, short circuit protection and over temperature and over power protection are all supported.
