Be Quiet! Power Zone 850W PSU Review

Testing results (Regulation & Ripple)


V3 V5 V12

The electrical performance of the Be Quiet! Power Zone 850W power supply is good; not excellent but not bad either, considering the class of the power supply. Voltage regulation is at 2.2% on the 12V line and, slightly higher, at 2.6% on the 3.3V/5V lines, which are very good figures even for high performance units. Ripple suppression however could have been better. Even though the figures were much lower than the 120mV limit on the 12V line and 50mV limit on the 3.3V/5V lines, there are many high performance power supply designs can do much better than that.

    “It is a very good product overall but still hard to find in the US. If you can find it for a reasonable price however, it would be a very good choice for a power-hungry gaming PC”

    Yep! I’ve been looking for one of the 1Kw versions and finally found one on newegg for $119.99 which is an amazing price when you take into consideration that these models were $189.99 at launch! Most reviews I’ve read say that it passes 80+ silver and even gold in some situations! Be Quiet is the number one manufacturer of PSU’s in Europe and I’m happy to finally get my hands on one! My R9 290 CF rig needs this PSU as it will not run with the current 800w Lepa PSU that I have now. As soon as it shows up on my doorstep and I have a chance to put it through the paces I’ll let you know what I think…great review by the way.
