Final Thoughts and Conclusions

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).
