Product Description
Be Quiet! Straight Power 12 850W Platinum Efficiency Silent Mastery
Ultimate Power Efficiency for Demanding Builds
The Be Quiet! Straight Power 12 850W sets a new benchmark in power delivery with its 80 PLUS Platinum certification and support for ATX 3.0 standards. With efficiency peaking at an impressive 94%, it ensures minimal power loss and reduced heat output. This not only lowers electricity costs but also contributes to quieter, cooler operation—ideal for premium gaming setups and professional workstations that demand both performance and precision.
Prepared for the Future of PC Hardware
Built to fully comply with ATX 3.0 and PCIe 5.0 specifications, this PSU offers maximum versatility and forward compatibility. It comes equipped with both the high-capacity 12VHPWR connector for next-gen GPUs and multiple PCIe 6+2-pin connectors for current high-performance cards. Backed by a powerful single 12V rail, it confidently handles power excursions up to twice its rated wattage—perfect for modern CPUs and GPUs with sudden power spikes.
Whisper-Quiet Cooling with Premium Components
Featuring a virtually silent 135mm Silent Wings fan with fluid-dynamic bearing and a 6-pole motor, the Straight Power 12 delivers optimal cooling with minimal noise. The funnel-shaped air intake enhances airflow efficiency, and the wire-free internal design reduces resistance while improving cooling. High-quality Japanese 105°C capacitors further ensure long-term reliability, making this PSU a cornerstone for any high-end, quiet, and future-proof PC build.
