Exceptional efficiency for GamersPower 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 CERTIFIEDHighly efficient operationPower 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 COOLINGEnjoy the silenceA 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 FANSpecially designed for Power Zone 2No 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. The fan offers outstanding reliability and makes for a long-lasting companion. Due to its large diameter, the fan cools the interior of the PSU efficiently and quietly.FUTURE-PROOF YOUR SYSTEMWith 90° angled 12V-2x6 connector in scope of deliveryPower Zone 2 850W is an ATX 3.1 PSU and comes with both native integration of the 12V-2x6 connector for next-generation PCIe 5.1 graphics cards, and 3 PCIe 6+2-pin connectors for support of current-gen GPUs. A 90° angled 12V-2x6 connector in the scope of delivery leaves no doubt that this PSU is here to stay. All of this makes Power Zone 2 850W extremely versatile and the perfect choice for powerful systems of today and the ones to come.THE NEW STANDARD OF POWERFor massive transient loadsPower Zone 2 offers 850W of continuous power with one massive 12V rail. Even if the graphics card demands excessive power for a short time: Power Zone 2 850W handles power excursions up to double its rated power with ease. This ensures reliable operation with the next generation of processors and graphics cards.HIGH-CLASS TECHNOLOGIESAll packed in a stunning designWith its LLC topology, the Power Zone 2 850W offers best-in-class voltage regulation and efficiency. This makes it perfect for building very quiet systems or upgrading gaming and media creation PCs. The inner values are what everyone cares about most in a power supply but looks cannot be completely ignored. That is why the Power Zone 2 850W has a distinctive look with a newly designed mesh front. In addition, all cable designations are printed directly on the PSU’s case for a long-lasting impression and an unparalleled look and feel.
