Introduction to the be quiet! Dark Power Pro 10 850W Power Supply

For a long time I wanted to review products from be quiet! as their representation for quiet and overall good performance really intrigued me. Until just recently we were able to get in touch with one of their associate and thus far we have not been disappointed with only one product been review which was the Dark Rock Pro 2 CPU cooler. There are two more products one which we will be presenting today and the Dark Rock 2 CPU cooler.

be quiet!’s take on the Dark Power Pro 10

Dark Power Pro supplies are already renowned as the world’s quietest PSUs in the high performance category. The Dark Power Pro 10 850W model takes that a giant step further with an all-new design topology that delivers 80PLUS Platinum performance, the world’s highest energy efficiency certification. Add to that an unparalleled array of enhancements that augment this unit’s compatibility, convenience of use, reliability, and safety, and the result is simply a power supply without equal. Simply put, this is the highest-powered, most technologically-advanced power supply be quiet! has ever built.

Closer look

be quiet! has long been known for great quality and performance paired with quietness. We saw this in the Dark Rock Pro 2 CPU cooler we tested. Their power supplies follow the same philosophy. We love the fact that we can have a quiet rig just as long as we get the performance we still demand.

The Dark Power 10 series consist of several units ranging from 550W to 1200W. With such a range be quiet! has all possible users covered. But to be more detailed there are a 550W, 650W, 750W, 850W, 1000W and 1200W unit. We will be testing the 850W model here today.

The Dark Power 10 has a certification from 80Plus for operating within the Platinum level spectrum. This warrant the five warranty the unit has.

The Dark Power 10 comes in a very nice dark black finish. The sides of the unit have a rubber sleeve on top of metal to reduce any vibration make between it and the PC case. This one feature here is something that we have not seen yet on a PSU and tells that be quiet! is thinking outside the box in a good way.

To make sure the internals are cool and continue to work as they should the unit is equipped with a 135mm SilentWings cooling fan. To secure the fan to the housing of the PSU, rubber fastens are used once again eliminating vibration from the unit. The fan is a fluid dynamic bearing unit that is rated at 2000 max with a max dBA of 24.2.

The rear of the chassis is not much better from many other power supplies but we have to state that the entire side is perforated for better air circulation.

It’s really nice to see some of the thing we did when it came down to the opposite side of the Dark Power 10. First, we see that only the main ATX connection is a permanent fixture. All the other cables have to be connected individually. PCIe plugs are along the top while the SATA and other cable plugs are aligned vertically in the center of the side plate. Also there are four fan connections as well.

Another unique feature of this unit is the ability to switch between quad 12v operation and single 12v mode. be quiet! considers the single mode to be the overclock mode or OCK. The default mode is quad but it can be switch via two different routes. The first is from a toggle switch that is mounted in a spare PCI expansion slot and the other is by a small jumper that would be it in overclock mode.

Results

We know that testing a power supply on a loaded system is not the very best way to do so, but you cannot overlook real world testing. Other sites have methods that use thousands of dollars in equipment to provide them greater detail. We have a trusty digital multimeter. Those sites and the methods they use should be the true means of determining how good a power supply really is; however, we feel that showing you how it performs under real world conditions is also a valid measure of its performance.

Conclusion

I have never been one to get too excited about doing a power supply review nor have I been one to get excited about the performance of a power supply. Reasons being if you get a good quality one and stay away from the ‘el cheapo’ ones you are good to go. Well, in most cases anyway. But from the moment I opened the box of the be Quiet Dark Power 10 my mindset changed. Never have a seen a power supply that comes with as many extras as these. Yeah true, accessories don’t make a power supply great. Right, but the Dark Power also has the performance numbers in its corner as well.

The looks of the unit is also very appealing. Its clean, very subtle to an extent but not plain either. The rubber pieces that surround the unit keeps one from have to install any type of noise isolator as it is all self-contained. The grill that protects the fan is very stylish and totally different from that of the typical PSU.

There are many features to the Dark Power Pro but one that stands out to me is the cabling. Modular cables are the fad right now but I have yet to find a reason to make the main ATX connection modular. Ok, there is one it makes it easier to individual sleeve, if that is your thing. But if not there are no other reasons for it. And with the Dark Power it is the only connection that is a permanent fixture.

Our only issue we could find someone running into is finding one in the U.S. We tried various sites to no avail. In Europe there is no problems locating one.
