When it comes to a high end desktop or a multi GPU workstation, you might think that CPU and GPU selection are the most important component, but none of the components will work without a suitable power supply. When it comes to a multi-GPU configuration, you’ll either suffer instant shutdowns or hardware damage if you haven’t got a PSU that can deliver on the massive power demands, and also one that can maintain such high power output for extended periods of time. Selecting a capable power supply is vital for system stability and longevity. The be quiet! Dark Power Pro 14 IO 1600W is built specifically for uncompromising gamers and professional users who demand reliable power delivery for longer gaming and work sessions. And of course, without sacrificing acoustic performance. Renowned for their German engineering, the be quiet! brand has designed this unit to handle extreme workloads and intensive overclocking sessions while maintaining exceptionally low noise levels. But most importantly of all, the ultra efficient voltage regulation and a clean power deliver we’ve come to expect from their flagship PSUs over the years.
Features
The Dark Power Pro 14 IO 1600W introduces several unique selling points that separate it from standard power supplies, most obviously its integration with the new IO Center software. This allows users to monitor real time efficiency, fan speeds, and power consumption directly from their desktop, while also offering the ability to switch between multi rail and single rail power delivery modes. As I said, this is an enthusiast focused PSU, so if none of that sounds like something you feel you need, it’s likely overkill for your needs. Cooling is managed by the superb be quiet! Silent Wings fan mounted within a custom aluminium heat sink, which supports both active and semi passive modes to keep the fan completely off during lighter workloads, although for a 1600W lighter loads is likely still a pretty high wattage. Furthermore, the unit uses a fully digital control design with an active rectifier and full bridge LLC technology to provide superior voltage regulation and lower ripple noise.
