About this product

Exceptional efficiency for Gamers Power Zone 2 850W is a power supply with 80 PLUS® Platinum certification and semi-passive zero-RPM cooling for both efficient and quiet gaming sessions.

PLATINUM CERTIFIED

Highly efficient operation Power Zone 2 850W is certified with 80 PLUS Platinum and Cybenetics Platinum, resulting in an energy efficiency rating of up to 94.1%. This results in lower power consumption, overall cooler and quieter operation, and many other benefits for your high-end system.

SEMI-PASSIVE ZERO-RPM COOLING

Enjoy the silence A large Pure Wings 3 140mm fan is keeping Power Zone 2 850W cool. While under low load, the fan turns off completely until its services are needed again for more demanding operations. This post-ventilation requires a short cooldown period of 2-5 minutes to avoid frequent and annoying starts and stops of the fan. Combined with the large fan for active cooling, this power supply is exceptionally silent in all load scenarios.

PURE WINGS 3 FAN

Specially designed for Power Zone 2 No Power Supply is like the other. Hence, we have altered aspects of our renowned Pure Wings 3 140mm fan to make it the perfect match for Power Zone 2 850W.
