be quiet! Dark Power Pro 11 850W Power Supply Review

Installation & Testing
Getting the Dark Power Pro 11 installed is quite easy, but be sure to use the included screws as they need to be longer since this unit has the rubber around the end. Normal screws will not work.

Remember since this unit is almost all modular you only use the cables that you need. In our system we did not run into any problems with cable lengths or cables not working correctly.

Disclaimer: We do realize that our testing methods for power supplies are not up to the standards that we would like. Unfortunately we do not have the equipment to properly test power supplies the way that we would like. The tests below do give you a good idea of how the unit will perform, but we know they are not as accurate as we would like. All power supply manufactures are made aware of our testing methods before they send us a unit.

Multimeter Testing

Our first set of tests we will be using a Mastech MS8268 digital multimeter. Here we will measure the rails at idle (Windows Desktop) and then at load (Heaven Benchmark looped). This will give you a good idea of power fluctuation during gaming sessions.


Software Testing
Our motherboard allows us to monitor the rails on our power supply. We do the same type of test we did with the multimeter and recorded the voltages.


The software also allows us to see a live view of the voltages on the rails. Here is what we were shown during our load test.




So as you can see based on our findings here we do have good voltage regulation.
