Special Features
- 80 PLUS Gold certified
- Quality components
- Adjustable cooling
- Ultra-stable voltage regulation
- Fully modular and RYZEN compatible
- Equipped with all safety features
Product features
- 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.
