The be quiet! Dark Power 14 1200W represents the pinnacle of PSU engineering, delivering unparalleled efficiency, silence, and reliability for demanding PC builds. Certified 80 PLUS Titanium, it achieves up to 95.57% efficiency, minimizing heat and energy waste even under full load. Compliant with the latest ATX 3.1 and PCIe 5.1 standards, this fully modular power supply supports next-gen GPUs with two native 12V-2x6 (PCIe 5.1) connectors and four additional 6+2-pin PCIe cables for legacy hardware.

Equipped with the custom Silent Wings 140mm fan featuring zero-RPM mode at low loads, it operates whisper-quiet: 8 dB(A) at 20% load, 8.3 dB(A) at 50%, and 21.1 dB(A) at 100%. High-quality Japanese capacitors (105°C rated) ensure longevity, while a full bridge LLC topology with synchronous rectification and DC-DC design provides rock-solid voltage regulation and clean power delivery. Four independent 12V rails (33/33/45/45A) handle up to 1200W continuous, with 1341W peak capability.
