Packaging and Accessories

front packaging

We begin the review of the be quiet! Dark Power 13 850W facing its packaging, a black and elegant box that shows us the desEsports Extrasof the source on the front and its distribution of rails on the back, but few features or technical specifications.

inner packing

Inside the cardboard box, we find the source protected by a foam frame and a second box containing the modular wiring and accessories.


be quiet!  Dark Power 13 - Accessories

In addition to the user manual, we find a fairly extensive set of accessories that consists of velcro and plastic ties to organize the wiring, two sets of installation screws (conventional and manual), the power cable and a small slot that, with a cable and a switch, it allows to convert the 4 rails of 12V of the source in a single one of 12V.

Fully modular wired cabling

be quiet!  Dark Power 13 - Modular wiring

But most important is the fully modular wired cabling that includes the be quiet! Dark Power 13 850Wwith a large number of connectors as we summarize below with their measurements.

  • 1 ATX cable (24+4 pin) [60 cm]
  • 1 EPS 12V (8-pin) cable [70 cm]
  • 1 EPS 12V cable (4+4 pins) [70 cm]
  • 1 PCIe Gen 5 / 12VHPWR (12+4-pin) cable [60 cm]
  • 2 cables with 2 PCIe connectors (6+2 pins) [60 cm]
  • 2 cables with 3 SATA connectors [60 + 15 + 15 cm]
  • 1 cable with 4 SATA connectors [60 + 15 + 15 + 15 cm]
  • 1 cable with 2 SATA + 2 MOLEX [60 + 15 + 15 + 15 cm]

PCIe Gen 5 12+4 pin cable

We have taken an additional photo of the PCIe Gen 5.0 or 12VHPWR cable 600W, 16-pin or 12+4-pin. This allows the passage of up to 600W of power, so it is compatible with the new generation of NVIDIA graphics cards, even with the RTX 4090.

DesEsports Extrasof the be quiet! Dark Power 13 850W

be quiet!  Dark Power 13 - Fan

We focus the review of the be quiet! Dark Power 13 850W on the exterior desEsports Extrasof the power supply itself. We are faced with a model ATX that offers some dimensions of 150 x 86 x 175mm (width, height, depth) and quite an attractive design, especially in the form of the fan grill.


It has inside a Silent Wings 135mm fan which promises a minimum loudness of 19.8 dB at maximum performance. Of course, it does not have a semi-passive mode as it is so fashionable, although it is not necessary to be virtually inaudible with the equipment at rest.

be quiet!  Dark Power 13 - Logo

On the side that will surely be visible after installing it on the chassis, we find the logo of the brand and the model in very well finished chrome stickers. Meanwhile, on the opposite side, we find the usual rail distribution sticker. In it we see reflected that the be quiet! Dark Power 13 850W has 4 12V rails of 30, 30, 35 and 35 amps respectively. However, we cannot maximize all of them at the same time, since the maximum combined power for all four is 840W, within the total of 850W offered by the power supply. Of course, we can use the included accessory to bridge a switch on the internal side of the source and thus convert them into a single 70A rail.

The be quiet! Dark Power 13 850W It also has numerous connectors on the internal side for modular wiring, all well labeled and well organized, highlighting the latest generation 12VHPWR.

While, on the opposite side, we see the standard C21 power connector for power supplies, as well as the complete power supply off switch.

80 Plus Titanium Certification

80 plus titanium

This model has the energy efficiency certificate 80 Plus Titaniumwhich guarantees an efficiency greater than 92% from 10% load, improving up to 95.4% at 50% load to go back down to 93.5% at 100% load.


Interior of the be quiet! Dark Power 13 850W

be quiet!  Dark Power 13 - inside

At this point, we have to say that we have not been able to open the power supply because the screws were too tight and when trying to remove them, one has lost his mind. That is why we use an official image, perfect to see that the interior of the power supply is very well organized and free of cables, except for the fan. We are dealing with a full bridge + LLC typology together with an active rectifier for the alternating current side. It also has DC-DC converters for the 3.3V and 5V rails, as well as a 105º Japanese main capacitor. There is also no lack of protection against excess current, voltage, power or temperature, as well as lack of voltage or short circuit.

be quiet!  Dark Power 13 - Voltages

We have analyzed the stability of the voltages with Aida64 Engineer for the +12V, +5V and +3.3V rails. To do this, we have subjected the equipment to the stress test of this software, checking how the values ​​are close to the theoretical and quite stable, within the margins required by the ATX standard.

be quiet!  Dark Power 13 - Consumption

For its part, the consumption towards the electrical outlet of the complete equipment with this power supply is within what is expected for an 80 Plus Titanium model with 705W peak stressing both the processor and the graphics card.




We conclude the review of the be quiet! Dark Power 13 850W being very clear that we are facing an excellent power supply for a high-performance equipment. It offers exceptional energy efficiency as guaranteed by its certified 80 Plus Titaniumas well as a tiny loudness as we have been able to verify in our tests. In addition, since it incorporates the 12VHPWR connector, it is ideal for next-generation computers with NVIDIA GPUs, although we can also use it with classic 8-pin PCIe connectors without any problems.

we can find the be quiet! Dark Power 13 850W for sale starting from 214.90 euros for the 750W model. follows the analyzed model of 850W for 259.90 euros and will also be available on 1000W for 294.90 euros. If we take into account their 80 Plus Titanium certificate and that they have a 10-year warranty, they are really good prices, although far from those offered by simpler ranges with, for example, 80 Plus Gold certificate and, above all, without the 12VHPWR connector.
