be quiet! are a powerful force for high-end power supplies, with many of the absolute best units on the market today. Actually, they have such a strong history that they’ve had many of the best power supplies for many generations of PC hardware. Flashback to 2013 when the original Power Zone launched with its single-rail design and award-winning performance. Now after all these years, it’s back again as the Power Zone 2! As be quiet! themselves say “it has taken over 10 years, but Power Zone 2 is again pushing the boundaries and is introducing new concepts to the world of be quiet! power supplies. And yes, it is also a single-rail PSU, but it is so much more than that.” So, let’s dive in and take a look at what it has to offer.
be quiet Power Zone 2
The Power Zone 2 is the first be quiet! PSU with semi-passive cooling, but they always equip their units with such high-quality silence-focused fans, that it’s rarely needed. The fan is a modified Pure Wings 3 140mm, one of the best fans on the market today. be quiet! say they’ve given it a relatively flat fan curve too, so you don’t hear any sudden spikes in fan noise. They also claim to have put a focus on reducing coil while, through their component choices, manufacturing and even some simple things like adding glue to reduce unwanted vibrations.
What be quiet! Had to Say
“We would love to say that our Power Zone 2 is completely silent in zero RPM mode, but that is simply physically not possible. So, we settle for the next best thing, which is “so quiet that it is not measurable in an anechoic chamber with a noise floor of 6.5 dB(A)”. To certify the low noise, we worked with Cybenetics and achieved the best possible Lambda rating of A++ for all Power Zone 2 models, which means their average noise over the whole load range is less than 15 dB(A). Cybenetics also grants a Platinum efficiency rating, which is matched by an 80 PLUS Platinum certification.
Power Zone 2 Design
As an ATX 3.1 power supply, the Power Zone 2 features 12VPWR support, for current and next-gen graphics cards. The topology is based on a half-bridge LLC with synchronous rectification and DC/DC conversion. For power outputs, you can choose from a 1000W, 850W or 750W variant to suit your needs. This range covers the most popular wattages for high-end gaming PCs and leaves enough headroom for future upgrades. Backed by a 10-year warranty, Power Zone 2 is the ideal and future-proof PSU for anyone who is looking for a highly efficient and silent power supply.
