Introduction


We would like to thank Be Quiet for supplying the review sample.

When you hear the name Be Quiet, the first thing that comes into your mind is minimal noise output since this is the primary goal of this company for all of their products. According to them the Dark Power Pro PSUs are already renowned as the world's quietest ones in the high-end category and of course their successors will honor this tradition. The Dark Pro P10 series will include six units with capacities ranging from 550W to 1200W. All feature state of the art technology to achieve Gold and Platinum efficiency levels (850W model).

The Dark Power Pro key features include the SilentWings 2 fan which with the Fluid Dynamic Bearing (FDP) promises 300,000 hours lifespan and minimal noise output, the new platforms on which they are based exploit Full Bridge (Half Bridge for units under 750W) topologies along with synchronous rectifying and DC-DC converters in the secondary side and finally the overclocking key. The latter allows the user to easily choose among multi-rail +12V mode and single-rail mode. From the factory all units are set to multi-rail mode but if the user thinks that a single +12V rail is better for his system or if he simply doesn't want to worry about OCP triggering, then with a quick flip of a switch or by using a jumper he can combine all +12V rails into a single powerful one. This sounds interesting although we don't know how many users will actually use this feature.

Today's review sample will be a Dark Power Pro 10 with 550W capacity, the smallest member of the family. Despite its small capacity this unit packs some really interesting features which we are going to analyze later in this review.

The unit is 80 Plus Gold compliant and its max operating temperature reaches 50°C. Also it includes all available protections and is equipped with a top quality and ultra-silent fan. Its dimensions strangely enough are quite large for its mere 550W capacity and the same applies to its weight, too. Finally its warranty is long enough at five years and the MSRP is set high, at $129.

With the default configuration the PSU has four +12V rails which can deliver almost its full power. However if you utilize the overclocking feature you can combine all +12V rails into a single rail. The minor rails can deliver 110W, a sufficienct power level for today's standards and finally the 5VSB rail is quite strong, for the category of the unit.

The PSU has an amazing amount of cables/connectors considering its small capacity. Five PCIe connectors, two pairs for VGAs and one for motherboard connection and three EPS connectors can be used at the same time, on paper at least, since the capacity sets the limit here. Also there are in total nine SATA connectors and six Molex ones along with four fan connectors. We have seen PSUs with far higher capacity featuring less connectors! Finally there is one more cable which feeds the overclocking key PCB. All cables are nicely sleeved and their length is ideal. Also the distance among all connectors is the recommended one, by ATX spec.
Regarding gauge size all connectors use 18AWG wires which are suitable for a PSU of this category/power.

Packaging


The box is really huge and initially, before we take a close look at it, we expected to find a 1000-1200W unit inside it. Apparently the PSU is accompanied by a rich bundle so a large packaging was essential. Also as we saw on the previous page, the length of the unit is equal with the corresponding of the larger ones, so it needs the same space. The face of the box looks rather empty since the dark background prevails and only several badges along with an angled shot of the PSU break the black monotony.


On the sides of the box we find various information like the benefits from using Gold efficiency PSUs instead of lower efficiency ones and the various award badges that the PSU earned from review sites. So far Techpowerup isn't listed among them.


The rear side of the box includes more detailed information about the PSU. More specific an illustration shows all available cables/connectors along with their respective lengths. Also there is a scheme showing the unit's dimensions and finally a brief features description in three languages: English, German and French.
