Be quiet! continues its extensive development of the Pure Power series by relying on the newest technologies. The 400-watt and higher models utilize the so-called “Active Clamp + SR” topology which leads to increased efficiency. The Pure Power 9 achieves an efficiency of up to 91 percent, leading to an 80 Plus Silver certification and a top performance in this price segment. The lower wattage models are 80 Plus Bronze certified. By implementing two independent 12 volt-rails, be quiet! is able to further improve the signal stability compared to its predecessor.
The Pure Power 9 also complies with the Energy Star 6.0 and ErP 2014 guidelines and supports the C6/C7 low power states of modern Intel processors. All common protection circuits are integrated into the new power supply series. These include UVP (under voltage protection), OVP (over voltage protection), SCP (short circuit protection), OPP (overload protection), OCP (over current protection) and OTP (overheating protection). In addition, be quiet! installed a “Surge Absorber”, offering multiple protection against voltage surges. This feature is unique in this price class and guarantees maximum safety for the Pure Power 9.
New components and optimized fan for quiet operation
Alongside the improved “Active Clamp + SR” topology, be quiet! has optimized components to prevent power supply noise caused by extreme load changes of modern graphics cards. Further noise reduction comes from a comprehensive optimization of the fan: the new 120 mm fan is based on the Pure Power L8, but significantly reduced both the motor and bearing noise. Combined with the air flow-optimized rotor blades and additional, separate temperature control sensors, this results in the best noise-to-cooling performance ratio. Overall, the Pure Power 9 is much quieter than the previous model.
Modern cables with all required connectors
be quiet!’s new models now sport black sleeved high-quality cables, which leads to a clean and modern look in the PC. One of these cables is an “all-in-one” cable with a practical Easy-Plug HDD connector. The Pure Power 9 series comes with four (600 and 700 watts) or two (400 and 500 watts) 6 + 2 pin PCI-e connectors and is ideally equipped for high-end or dual-GPU systems. The 300 and 350-watt models offer a 6 + 2 pin PCI-e connector as well. As a result, the Pure Power 9 offers the best possible combination of features, performance, and quality at an attractive price point.
The Pure Power 9 is available in all watt classes with MSRPs between €49.00 / £37.99 and €99.00 / £74.99.
