Product Overview

No Compromise Silence and Performance

Dark Power Pro 11 850W is be quiet!’s most advanced PSU ever. With 850W of continuously available power and an overclocking key that switches between four-rail and single-rail operation, it has sufficient reserves to support any multi-GPU or multi-CPU system you could want to build. be quiet!’s virtually inaudible Silent Wings 3 fan and an unparalleled array of noise-reducing enhancements make it the quietest PSU in its category, perfect for powerful applications that nevertheless need significant quietness. And its full bridge power topology earns it one of the highest power efficiency certification available — 80 PLUS® Platinum.


80 Plus® Platinum Certified

Dark Power Pro 11 850W is certified with 80PLUS® Platinum and an energy efficiency rating of up to 94%. This provides lots of benefits for your high-end system, including less power consumption and an overall cooler and quieter operation. The standby drain is below 0.1 watts.


Silent Wings 3 Fan

The decoupled be quiet! Silent Wings 3 135mm fan provides virtually inaudible operation. This is thanks to its unique, airflow-optimized fan blade design along with an advanced fluid-dynamic bearing and 6-pole fan motor for less vibration, super-long life and minimal power consumption.


Funnel-Shaped Fan Opening

The fan inlet of the Dark Power Pro 11 850W is funnel shaped. This causes an increased throughput of air, which results in higher cooling performance.


Ready for Overclocking

Dark Power Pro 11 850W is particularly suitable for overclocking, thanks to its strong and stable 12V-rails. The overclocking key empowers you with full control for overclocking by manual switching between the default four 12V-rail mode and the alternative massive single-rail operation.


Equipped with High-End Features

Dark Power Pro 11 offers 850W of continuous power with four independent 12V-rails for excellent signal stability and nine PCI express connectors for multi-GPU systems. Up to four case fans can be connected to, and regulated by the PSU.


Maximum Convenience

The maximum utility afforded by extra-long sleeved cables of up to 120cm and modular cable management simplifies component installation and reduces annoying clutter. This succeeds in increasing the airflow and improving the cooling in even the largest PC cases.


State-Of-The-Art Technologies

Experience the most technologically advanced power supply be quiet! has ever built! Using an advanced full bridge, LLC and Synchronous Rectifier (SR) technology it provides unmatched signal stability and unbeatable power efficiency. It is also equipped with DC-to-DC conversion for tight voltage regulation, even under heavy cross-loading conditions. This ensures reliable operation for the next generation of processors and graphics cards.


Japanese 105° Capacitors

Only the best components are used in Dark Power Pro 11 850W. That is why we have built exclusively high-quality Japanese capacitors into the PSU chassis. They are rated to 105°C which ensures stability, reliability and a long operating life.

Date Issued: 28th Apr 2020

Power-supply units, or PSUs, are an integral part of any computer build. Often overlooked, it is the component that is likely to last the longest, and it can be moved between systems when you upgrade to the latest and greatest in the future.

80 Plus certification
Date Issued: 18th Nov 2010

Conceived back in 2004 and brought to market just a year later, the 80 PLUS initiative is one of many standards introduced in an effort to increase energy efficiency in modern technology. Targeting computer power supplies, it awards PSUs that are able to achieve an energy efficiency of over 80 per cent at varying workloads and a power factor of 0.9 or more at 100 per cent load.

Reviews
850W be quiet! Dark Power Pro 11, Hybrid Modular, 80PLUS Platinum, SLI/CrossFire, Quad Rail, 70A, 135mm Fan, ATX PSU is rated 4.7 out of 5 by 3.
Rated 5 out of 5 by from Barely audible even with an open case. Had my eye on this for a while as already have the BeQuiet Dark Rock 4 for my CPU fan and was really impressed at just how quiet their products are - I tinker a lot and have an open testbed case (Aerocool Strike X Air) so there's obviously no noise insulation at all and you hear EVERY little whirr and shunt. Got this for Christmas and swapped out my perfectly functional but loud PSU. This worked like a dream. Aside from the initial power-on burst, currently the loudest noise on most loads is the HDD spin. I generally pull about 120W at idle, and 400-450W at working load. so I'm by no means stretching this supply to its limits. I did a few stress tests and it performs just my experience of the BeQuiet CPU coolers - below 70% you'll barely hear anything even with your ear right next to it; fan noise kicks in around 80-85% max load and quickly ramps up but is still a much smoother air noise than most supplies out there. There's some very minor wobble on the voltage rails but it's about stable as you can reasonably get without being a straight flat line. The inclusion of large thumb screws as part of the accessories was greatly appreciated in my set up where being able to swap things in and out easily is important. Plenty of cables included as well as zip ties and velcro loops to help with cable management. Only minor detail I might note that seemed odd was there was no acoustic padding or felt/rubber feet pads included with the accessories, which is the sort of thing I might expect from this brand. All in all very happy with this, and expect I'll be looking at BeQuiet products as my automatic go-to's for all future builds.

Rated 4 out of 5 by from Good - volume could be better Brilliant quailty , volume at load is good for PSU , but idle volume could be better. Cables are good quality and there is no coil whine. Had no stability issues in multi rail mode, not bothered with single rail mode so cant comment

Rated 5 out of 5 by from Excellent PSU, whisper quiet The summary says it all really. A very well put together PSU with a good selection of cables and documentation. The fan is barely audible even when under load, and that's only when you get your head right down close to it. Inside a closed case you'd probably never know it was there. Only point to bear in mind is this PSU has a depth of 180mm, which is a bit longer than some others, and may not fit some cases. Be sure to check what the maximum depth your case can accommodate is. It's a bit more expensive than the competition, but you definitely get what you pay for, and it's Platinum rated too!
