Power outages and noisy rigs can ruin a gaming session, but a reliable, whisper-quiet PSU keeps your system stable and silent. The be quiet! PURE POWER 12, 850W, 100 - 240 V, 50/60 Hz, 12 A, 6 A, Power Supply delivers clean, efficient power for high-performance PCs, protecting every component while staying barely audible.
Why Choose a be quiet! Power Supply
Unstable power can cause crashes, data loss, and shortened component life, especially under heavy loads. This power supply solves those issues with robust protection circuits and an 80 PLUS Gold rating, ensuring consistent voltage and high efficiency. You get a smoother, quieter experience without worrying about overheating or sudden shutdowns.
Usages of a 850W Power Supply
Ideal for gaming rigs, workstations, and content-creation PCs that demand a strong, steady power source, this 850W unit handles multiple graphics cards and high-end CPUs with ease, making it perfect for demanding builds and future upgrades.
Benefits of be quiet! Power Supply
You enjoy ultra-quiet operation thanks to a 12 cm rifle-bearing fan that stays below 25 dB. The high 90.5 % efficiency reduces electricity costs and heat output. Comprehensive protection guards against over-current, over-voltage, and short circuits, extending component lifespan. A single +12 V rail delivers up to 70.9 A for powerful GPUs, while the compact ATX form fits most cases. Active cooling and a solid 0.98 power factor keep performance stable under load.
