    Press release           System Power 9: Reliable power for system builders

Entry level power supply features 80PLUS Bronze certification and DC-to-DC technology at a low price

Glinde, February 13th, 2018 - be quiet!, the market leader in PC power supplies in Germany for eleven consecutive years*, introduces its System Power 9 series of power supplies with 400 to 700 Watts, and a bulk variant, the System Power B9 with 300 to 600 Watts. Both product lines offer 80PLUS Bronze level efficiency (400 Watts and upwards) - up to 89 percent, providing solid performance and an extensive feature set. All this, combined with a great price-performance ratio, makes this power supply series a perfect component for system builders.

Great for building cost-efficient and reliable systems

Each new power supply in the System Power 9 line-up is built with the latest technology and available at a competitive price, maintaining the quality and reliability expected from a premium brand like be quiet! All models, except System Power B9 300W and 350W, are 80PLUS Bronze (230V EU Internal) certified and feature improved voltage regulation thanks to System Power 9’s DC-to-DC technology. In every System Power 9 model, be quiet! implements a full range of circuit protection, including over temperature protection (OTP), while a temperature-controlled high-quality 120-millimeter fan constantly cools the power supply at a low noise level. System Power B9 is packed in production-optimized bulk packaging, ensuring quick and easy handling for system integrators.

High performance and multi-GPU capability

Two independent 12V-rails ensure highly stable power output to all PC components. System Power 9 power supplies with 400 and 500 Watts are equipped with two PCI-Express connectors, while 600 and 700-Watt versions offer four, making the power supply ideal for multi-GPU configurations. The bulk variants feature two PCI-Express connectors at 450 and 600 Watts and one at 350 Watts.

The best choice for office and multimedia systems

Outstanding characteristics make System Power 9 and System Power B9 perfect for quiet office and multimedia systems, as well as price-consciously built home theater PCs. The new power supplies also provide enough power for energy-efficient, entry-level gaming systems. Thanks to its compliance with Intel® C6/C7, ErP and Energy Star 6.1 guidelines and its power saving technology, both series achieve a low standby drain of less than 0.15 Watts. To help satisfy system builder aesthetics, sleeved black cables add a high-quality look to each power supply, while quality workmanship is paired with a three-year warranty that complete each System Power 9 and System Power B9 package.

The two power supplies are now available for purchase in Europe. System Power 9 is priced at an MSRP of €49.90 / £46.99 (400W), €61.90 / £57.99 (500W), €71.90 / £67.99 (600W) and €84.90 / £76.99 (700W).
