be quiet! Dark Power Pro 14 IO 1600W, ATX 3.1

Das Fazit zum be quiet! Dark Power Pro 14 IO 1600W fällt sehr positiv aus, da es eine gelungene Kombination aus hoher Leistung, sehr leisem Betrieb, guter Ausstattung und hochwertiger Technik bietet. On top zu diesem stimmigen Gesamtpaket hat be quiet! nun auch eine Softwareschnittstelle in Form der IO-Center-Anbindung gepackt, was sicher nicht alle User wirklich brauchen werden, aber zumindest müssten be-quiet!-Fans jetzt nicht mehr ganz so neidisch zur Corsair(&Co)-Fraktion hinüberschauen.

The be quiet! Dark Power Pro 14 IO 1600W belongs to be quiet!’s first power supply series with software control, through the company’s IO Center application. Built on a digitally controlled CWT platform, it combines Cybenetics Titanium efficiency at 115V, a Cybenetics LAMBDA A noise rating, two 600W 12V-2×6 connectors and IO Center integration for real-time monitoring, rail-mode switching and fan-mode selection. Let’s see how it performs.

In all my years in the industry I've yet to test a Dark Rock Pro power supply unit that didn't perform as expected and the Dark Power Pro 14 IO 1600W is no exception. Its excellent build quality, largely thanks to Channel Well Technology as the OEM, sets a strong foundation, while the unit follows through with rail stability that stays consistent even when the load shifts sharply. Noise output remains impressively low (first PSU in the lab to be inaudible during idle, even in performance mode), giving high‑end systems a quieter baseline, while the IO Center software adds meaningful control by letting you adjust fan behavior (semi-passive, performance) and choose between single‑rail or multi‑rail operation. The angled 12V‑2x6 connectors are a thoughtful touch that makes cable routing cleaner in modern GPU layouts. Its downsides are exactly what we’ve come to expect based on past models, meaning mainly the price and size, real considerations, which don’t overshadow the fact that this is a premium, purpose‑built unit for systems where stability, acoustics, and configurability matter more than anything else.
