be quiet! sweeps the competition with Dark Sweeper 1426W
Performance, silence, and cleaning meet in a high-performance power supply with integrated robot vacuum
April 1, 2026 - be quiet!, the German manufacturer for premium PC components and peripherals, announces Dark Sweeper 1426W, a high-performance power supply with integrated robot vacuum. Combining power, whisper-quiet operation and a clean PC has never been easier: Dark Sweeper 1426W is designed to clean case side panels, fans, motherboards, keyboards and much more, while delivering ATX 3.1 compatibility with full support for modern graphics cards. With dust laser detection, up to 30,000 pa suction power, up to 4,000 pa downward pressure, automatic vacuum and AFK (Away From Keyboard) functions, as well as full software control through be quiet! IO Center, Dark Sweeper 1426W brings performance, silence, and cleaning together in a way that only be quiet! can.
“Dark Sweeper 1426W is the result of asking a very important question: why should a power supply only power your PC when it can also clean it?” said Aaron Licht, CEO of be quiet!. “With whisper-quiet operation, intelligent autonomy, and enough suction power to make dust reconsider its life choices, Dark Sweeper may be our cleanest innovation yet.”
Compact integration with autonomous control
Dark Sweeper 1426W integrates a compact robot vacuum directly into the power supply in a design that fits virtually any case and does not look out of place inside a PC. Beyond internal components, it is engineered to clean side panels, keyboards, and other surfaces with the same precision and care. The automatic vacuum function handles routine cleaning independently, while the AFK function starts the vacuum robot automatically when the user steps away from the keyboard. Real-time user control via keyboard input and detailed configuration through be quiet! IO Center software provide complete control over performance and functions.
Laser-based dust detection and precision cleaning
Advanced laser-based dust detection makes even fine particles visible and helps avoid obstacles. With up to 30,000 pa of suction power and up to 4,000 pa of downward pressure, Dark Sweeper removes dust thoroughly and reliably. Smart mapping ensures seamless, edge-to-edge coverage for a consistently clean PC interior and exterior, while integrated pet evasion tactics add another layer of intelligent navigation.
Power, compatibility, and quiet operation
Dark Sweeper easily powers any high-end system thanks to an unrivaled 1426 watt single-rail design with Full Bridge + Synchronous Rectifier + LLC technology that provides unmatched signal stability and extremely high efficiency. True to the be quiet! philosophy, performance never comes at the cost of silence: an integrated Silent Wings fan, switchable active and semi-passive cooling modes, and a high-performance aluminum heatsink support exceptionally quiet operation and long-term reliability. The integrated ATX 3.1 power supply delivers full compatibility with PCIe 5.1 GPUs as well as graphics cards using 6+2-pin connectors.
Dark Sweeper 1426W will be available only today for users that are eager for a clean power supply for their system.
