Be Quiet! Announces Pure Power 11 Series Power Supplies

Be Quiet!, the market leader in PC power supplies in Germany for twelve consecutive years, announces its new mainstream power supply series: Pure Power 11. The series consists of six models with fixed cables ranging from 300 to 700 watts and four models with modular cables ranging from 400 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.

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 rated 400 watts or higher are 80 PLUS Gold certified, peaking at 92% efficiency. The models with 300 or 350 watt output are 80 PLUS Bronze certified. 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. 400 and 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 series is available now in major markets except North-America. Market availability in the US is scheduled for beginning of December. Pure Power 11 CM with modular cables is available in 400W (€65.90/£59.99), 500W (€79.90/£69.99), 600W (€89.90/£79.99), and 700W (€104.90/£94.99). Pure Power 11 with fixed cables is available in 300W (€47.90/£42.99), 350W (€52.90/£47.99), 400W (€59.90/£52.99), 500W (€69.90/£62.99), 600W (€79.90/£69.99), and 700W (€95.90/£84.99).

Wait, someone made a gold-rated 300W PSU? Finally! A shame it's not modular. Still, that's about time. Not much choice in this space, and the wattage is perfect for entry-level gaming (heck, you could likely run an i5 8400+1070 off it with no problems), with the added benefit of not being all that inefficient at idle. Sure, for the price you can get cheapo Bronze 500W units, but efficiency and quality are well worth the slight added cost.

Now for them to stuff the same thing into a modular SFX design without jacking up the price too much.

Nope, someone just needs glasses.

Damn, that's what I get for skimming the article. I seriously don't get why this is so difficult. The market for low-output PSUs should be huge given how efficient hardware is these days, yet most lines seem to be 550W and up. At least the 400W is gold rated, and modular.

It won't be cheaper to make. A 300W PSU with the same price as the 400W wouldn't sell good. Also it's quite possible the Pure Power 11 400W does 80PLUS Gold with 300W load. The efficiency is on the high side with 20% load. That's because the Active Clamp Reset Forward design, high efficiency with low loads with a design like this.
