The be quiet! Power Zone 2 850W is a quiet and efficient PSU, which is equipped with an angled 12V-2×6 connector, so it is ATX v3.1 and PCIe 5.1 compliant. Read the full review about its performance.
The be quiet! Power Zone 2 850W ATX v3.1 is (or will be) included in my best ATX v3.x & PCIe 5.x PSU picks article.
The Power Zone 2 line by be quiet! Includes three members with capacities ranging from 750W to 1000W. All are ATX v3.1 compatible and come with 90° angled 12V-2×6 connectors, preferred by users with NVIDIA graphics cards, since AMD hasn’t officially jumped to the new PCIe connector yet. Given the issues we see on NV’s cards, I cannot blame AMD for hesitating. On the other hand, it is NV’s fault that it didn’t include the necessary protection features in its designs. This is another story, though.
In the be quiet! PSU portfolio of PSU products, the Power Zone 2 line is below the Straight Power 12 and the Dark Power 13 lines, and above the Pure Power 12.
| POWER ZONE 2 1000W | 190€ / $190 |
| POWER ZONE 2 850W | 170€ / $170 |
| POWER ZONE 2 750W | 150€ / $190 |
The Power Zone 2 PSUs have higher prices than similar capacity and spec models from other brands, but given that a PSU’s purchase is an investment, which you only have to do once a while (4-5 years in average) I cannot say that paying 30-50 dollars more to get a good PSU is a lousy investment. On the contrary, PSU prices are down to earth compared to other IT parts like GPUs, CPUs, and mainboards. It sounds crazy, but some users can spend thousands of dollars on a GPU and prefer to buy a cheap PSU with the leftover money.
