850 WATTS CONTINUOUS POWER OUTPUT

With the massive 12V rail design the Power Zone can deliver up to 840W on the +12V rail, respectively 98.8% of the total power. This feature makes Power Zone the perfect PSU for overclocking your CPU and GPU.

SILENT WINGS FAN

The high-end Silent Wings 135mm fan with variable speed delivers best-of-class airflow yet produces very little noise. This is thanks to its unique, optimized fan blade design alongside an advanced fluid-dynamic bearing and 6-pole fan motor that largely eliminates operational noise, has a super-long life and minimal power consumption.

ADVANCED COOLING FEATURES

Up to three case fans can be temperature-controlled by the PSU, resulting in an optimized and quiet system. The “cool-off” feature continues to run the fans for an additional three minutes after a system shutdown, protecting valuable components at their time of maximum heat stress.

INNOVATIVE TECHNOLOGIES

The use of Active Clamp and Synchronous Rectifier technologies guarantees a very stable operation. The PSU is equipped with DC-to-DC conversion for even tighter voltage regulation under heavy cross-load conditions. This ensures secure operation for next generation processors and graphics cards. Power Zone is designed for powerful operation even at 50°C.

MODULAR CABLES

Thanks to the modular cables, all cables that serve no purpose in the system are left out, which makes for tidier systems and easier installation of the PSU. The uncluttered layout means a smoother airflow, which leads to lower noise and temperatures inside the case.

JAPANESE 105° CAPACITORS

Only the best components are utilized in Power Zone 850W. That is why we have used only high quality 105°C-rated capacitors on both AC and DC side for maximum performance, high reliability and longer PSU life under high load.
