Thanks to its LLC topology, the Power Zone 2 850W offers the best voltage control and efficiency. Perfect for quiet systems or gaming and media PCs. The inner values are crucial, but the appearance also counts. The Power Zone 2 850W has a distinctive look with a designed mesh front. All cable designations are printed directly onto the case for a lasting impression and unique appearance.
Power Zone 2 provides 850W continuous power via a high-performance 12V rail. Even if the graphics card retrieves excessive power for short periods, Power Zone 2 850W can handle peak loads up to twice the rated load without any problems. This ensures reliable operation with the next generations of processors and graphics cards.
Power Zone 2 850W is certified with 80 PLUS Platinum and Cybenetics Platinum, resulting in efficiency up to 94.1%. This ensures lower power consumption, overall cooler and quieter operation and many other benefits for your high-end system.
Power Zone 2 850W is an ATX 3.1 power supply and features both a native 12V-2x6 connector for next-generation PCIe 5.1 graphics cards, as well as 3 PCIe 6+2 pin connectors to support Current-Gen GPUs. A 12V 2x6 connector with 90° plug included leaves no doubt that this power supply is here to stay. All this makes Power Zone 2 850W extremely versatile and the perfect choice for today's and tomorrow's powerful systems.
No power supply is like the other. That's why we took our renowned Pure Wings 3 140mm fan and changed some aspects to make it the perfect solution for Power Zone 2 850W. The fan offers excellent reliability and is a durable companion. Thanks to its large diameter, the fan cools the inside of the power supply efficiently and quietly.
A large Pure Wings 3 140mm fan keeps the Power Zone 2 850W cool. At low load, the fan switches off completely until it is used again for more demanding applications. A re-ventilation phase of 2-5 minutes during cooling prevents frequent and annoying starts and stops of the fan. In combination with the large fan, this power supply is exceptionally quiet in all scenarios.

Versatile application in various environments. Our energy saving device is suitable for air conditioners, washing machines, refrigerators, water pumps, induction cookers, kettles and more. It prevents electrical overheating and works smoothly under rated load. Please note that small appliances such as fans or LED bulbs do not offer significant energy savings.
Save energy and money with our first-class energy saving device! Our innovative technology helps reduce electricity costs by regulating voltage, balancing current, and providing surge protection. By optimising energy consumption and avoiding unnecessary power use, our device extends the life of your electrical appliances.
Safety and reliability are top priority. Our energy saving device gently releases the stored energy via a capacitor system, avoiding voltage spikes at rated load. The housing is made of advanced fire and explosion-proof material, and internal leakage protection measures ensure maximum safety and reliability.
Maximum results without effort. For optimal performance, we recommend using one unit per 50 square meters. Place it in the sockets closest and farthest away to your power connector. Our device works 365 days a year and can reduce your electricity bill by up to 40%.
Easy to use. Simply plug the device into a socket - the green indicator light will light up and indicate that it is working. Leave the device connected to reduce energy consumption and save 20-35% energy under high current load. The first savings will be noticeable after about a month.
