Be Quiet! Dark Power Pro 10 850W Power Supply Review

Final Thoughts and Conclusions

View Full Size

Be Quiet! has taken an already great power supply in the form of a Seasonic X-series unit, and made it even better. The enhancements made to the Dark Power Pro 10 850W power supply translates to “legendary silence and cutting edge performance”; just like Be Quiet! claims.  The custom designed SilentWings fan is virtually silent at low to mid power levels. Voltage regulation is excellent, efficiency is excellent, the DC outputs are very clean, and the Dark Power Pro 10 850W PSU comes with an excellent assortment of modular cables and connectors. Add to that the ability to select either single or multi +12V rail operation, the ability to automatically control up to four case fans, Haswell CPU deep sleep state support, and rubberized end caps for noise and vibration isolation and you have a very interesting and competent new power supply.

The Dark Power Pro 10 850W power supply is currently selling for $239.99 USD (, May 2013).

Another amazing psu review and another amazing psu from seasonic made even better by Be Quiet.

Two questions: In what situation would the multi 12v rails be chosen over the single rail? I have always used single rail psu's beginning back with pc power and cooling years and years ago.

The second question is about the fluid dynamic verse double ball bearing. Is one better than the other?

You would use Multi-Rail for security reasons:
