Titanium efficiency meets ATX 3.0 readiness
This 850W PSU achieves up to 95.4% efficiency, reducing heat output and power draw. The 80 PLUS Titanium certification ensures minimal energy waste, while ATX 3.0 compliance provides native 12VHPWR support for PCIe 5.0 graphics cards and 6+2-pin connectors for current GPUs.
Virtually inaudible cooling system
The frameless Silent Wings fan uses a 6-pole motor with advanced fluid-dynamic bearings to minimise vibration. Fan speeds range from 0-1800 RPM, with intelligent fanless mode during low loads. The split fan inlet design increases airflow while reducing turbulence for extended component lifespan.
Built for extreme power demands
With 4 independent 12V rails delivering 850W continuous power, this unit handles transient loads up to 1700W. Japanese 105°C capacitors ensure stability during overclocking or heavy gaming sessions. The active rectifier and full-bridge LLC topology provide clean, stable power with minimal ripple noise.
Modular design for clean builds
Fully modular, sleeved cables up to 120cm long reduce case clutter and improve airflow. The 20+4 pin ATX and 4+4 pin CPU connectors, plus 12 SATA and 3 PATA power connectors, offer comprehensive compatibility for complex builds.
