The most powerful source of be quiet! arrives in September with up to 1600W

be quiet! has confirmed price and availability date for the Dark Power Pro 14 IOthe most powerful and advanced power supply that the German brand has manufactured to date. The series will arrive starting September 1 in two versions, 1300 W and 1600 Wwith 80 Plus Titanium and Cybenetics Titanium certification, the two most demanding efficiency seals in the sector.

The announcement comes months after be quiet! will show the Dark Power Pro 14 IO at Computex 2026, where its main technical characteristics were already known, but there were no specific price or commercial launch figures. With this confirmation, the source goes from being a technological advance to a product with a real purchase date.

The 1600 W model will have a recommended price of $499.90 (479.90 euros), while the version of 1300 W will remain at 479.90 dollars (439.90 euros).

IO Center adds an electricity cost calculator

One of the new features that accompanies this source is the IO Center softwarewith which be quiet! makes the Dark Power Pro 14 IO your first power supply with smart control from an app. The program allows you to switch between multirail and monorail modes, choose between active or semi-passive ventilation, and consult real-time data on efficiency, fan speed, and energy consumption on the panel itself.

Among the software functions, a electrical cost calculatorwhich shows the source’s electricity expenditure since the software was last started, the accumulated cost since the first time it was installed, and an estimate of the monthly expenditure. This is a type of data that until now was practically impossible to calculate accurately without external instrumentation, and that be quiet! now available to any home user directly from the source software itself.

Digital architecture with aluminum heatsink and semi-passive mode

Inside, the Dark Power Pro 14 IO uses a Fully digital control with Active Rectifier, Full Bridge and LLC technologydesigned to offer a stable output voltage even under variable loads and sudden consumption peaks, such as those generated by today’s high-end graphics cards. The newly developed aluminum heatsink works together with a Silent Wings fan integrated directly into the heatsink itselfwhich, according to be quiet! It makes it immune to vibrations and contributes to extending its useful life together with the fluid dynamics bearing it mounts.

The Dark Power Pro 14 IO comes with modular and individually sleeved cabling, plus four different sizes of cable combs, designed to facilitate organization and improve airflow inside the case once the system is assembled. Both models include protection against overcurrent, overvoltage, undervoltage, short circuits, overheating, overload and input voltage spikes.

be quiet! backs the source with a 10-year warrantythe same figure that usually accompanies its high-end models, and highlights that the design, manufacturing and quality control of the product are carried out in Germany. Aaron Licht, CEO of be quiet!, has presented the product as the result of the company’s years of experience in power supply engineering, highlighting software control and cooling flexibility as its main arguments against the competition.

Native support for PCIe 5.1 and 12V-2×6 connector

In the connectivity section, the Dark Power Pro 14 IO natively integrates the 12V-2×6 connector for next-generation PCIe 5.1 graphics cards, along with four 6×2-pin PCIe connectors designed to support current graphics cards that have not yet made the leap to the new standard. This dual compatibility seeks to ensure that the power supply serves both systems already built with previous generation GPUs and those who upgrade to the most recent cards without having to change the power supply.

Almost three months have passed between the presentation at Computex and the arrival in stores, a relatively long period even for a product of this level, in which be quiet! has had to finalize both the final price and regional availability before confirming the departure date. For those who are considering building or updating a very high-end device with high-consumption graphics cards, the Dark Power Pro 14 IO is now added to the catalog of options with a confirmed purchase date starting in September, although it is worth checking the actual availability in each store once the first weeks of sales begin.
