Be quiet!, the market leader in PC power supplies in Germany for twelve consecutive years, introduces its new mainstream power supply series, Pure Power 11, to the US market. The series consists of three models with fixed cables ranging from 500 to 700 watts and three models with modular cables also ranging from 500 to 700 watts. Previously, Pure Power 10 introduced DC-to-DC transformation to be quiet!'s best selling power supply series, improving crossload performance and voltage regulation on its minor rails. Pure Power 11 expands on this proven technology by upgrading both passive and active components, enabling higher efficiency of up to 92% with 80 PLUS Gold certification, and leading to less heat generation and quieter operation. Manufacturer warranty has also been increased from three to five years.Modern topology for excellent voltage quality and high efficiency
Pure Power 11's standout technology includes a DC-to-DC convertor, significantly improving both voltage quality on the 3.3V and 5V rails as well as crossload stability. The so-called "Active Clamp + SR" topology contributes to high efficiency ratings and stability. Pure Power 11 power supplies are 80 PLUS Gold certified, peaking at 92% efficiency. Up to 96% of the PSU's total power goes to the 12V rails powering the PC's critical components.

Silent operation with a proven cooling fan
Along with reduced motor and bearing noise, Pure Power 11's power supply fan is just as reliable as its predecessor's. The fan curve is automatically fine-tuned using an independent temperature sensor to control the airflow-optimized fan blades. Thanks to an overall increased efficiency the fan speed is reduced, resulting in a low noise level of no more than 25.9 dB(A).

High level of protection
The integration of all modern and relevant protection circuits is quite unique for a power supply series at Pure Power 11's price point. Included protection circuits are UVP (under voltage protection), OVP (over voltage protection), SCP (short circuit protection), OPP (overload protection), OCP (over current protection) and OTP (overheating protection). Also, a built-in surge protector safeguards the power supply against voltage spikes, guaranteeing maximum safety.

Premium design and cable management
Pure Power 11 follows be quiet!'s design philosophy and comes with high-quality black cables. Fixed cables are equipped with high-grade black sleeving for clean interior aesthetics, while the cable management models feature flat and easy-to-route modular cables for drives and PCI-Express connectors. 500 watt models provide two PCIe connectors to support multiple GPUs, while the 600 and 700 watt models are equipped with four PCIe connectors.
Pure Power 11 and Pure Power CM power supplies are available now with 500W and 600W at an MSRP of USD 64.99/74.99 (500W/CM 500W) and USD 74.99/84.99 (600W/CM 600W). Models with 700W will come to the market during the first quarter of 2019 for USD 84.99/94.99 (700W/CM 700W).
