Choosing a power supply
When choosing the right power supply, wattage is the key parameter alongside form factor. It indicates the maximum number of Watts that the power supply can continuously deliver to the computer components. We recommend using an online calculator to calculate the optimum wattage based on your chosen components.
Advanced protection with ThermalProtect technology
Innovative ThermalProtect technology on the included native 12V-2×6 cable monitors operating temperatures directly at the graphics card connector. If it detects dangerous overheating, it activates overheat protection and disconnects the power, preventing hardware damage. The comprehensive protection suite includes over-voltage, under-voltage, short-circuit, over-current, and over-power protection. High-quality electrolytic capacitors rated up to 105°C increase operational reliability and provide high thermal stability.
Power supply efficiency
Cybenetics Platinum certification confirms high energy efficiency reaching 91% under typical load. Higher efficiency reduces waste heat, power consumption, and the cooling demands of the entire system. The stable output voltage on the 12V rail with a 70.8A current powers even overclocked processors and the most powerful graphics cards on the market without voltage fluctuations.
Fully modular cabling
The fully modular design lets you connect only the cables your build actually needs. The package includes flexible cables with routing combs and a native connector for modern graphics cards without the need for adapters.
Silent power supply operation
Cooling is handled by a 120mm fan with an optimised blade curve for efficient heat dissipation. Zero RPM mode turns the fan off completely at low and medium loads, meaning the power supply operates in absolute silence. High-quality bearings and speed control keep noise levels low even during high loads, such as gaming or intensive computing.
Compact dimensions for easy installation
With a depth of just 140mm, this unit ranks among the most compact power supplies in its performance category. The smaller dimensions free up space in the bottom of the case to store excess cabling or install liquid cooling. The standardised ATX form factor ensures compatibility with most standard PC cases on the market.
Modern hardware standards
The power circuit design is built for the high peak power demands generated by modern processors and 50-series graphics cards. Support for Modern Standby enables fast wake times from sleep mode while maintaining low power consumption.
Reliable power without compromise
The total continuous output reaches 850W, providing plenty of headroom for gaming systems with a single high-performance graphics card. The power supply architecture efficiently distributes power across individual rails and reduces losses. Protection systems constantly monitor electrical parameters to ensure high safety for all connected components.

80 Plus certification in the European market
The 80 Plus certification provides an objective rating of power supply efficiency, making it easy for users to compare different models. The European market (operating at 230V) features six levels of 80 Plus certification with specific requirements for power supplies. Higher energy efficiency primarily means lower power consumption.
| Power supply load | Efficiency at 20% load | Efficiency at 50% load | Efficiency at 100% load |
|---|---|---|---|
| 80 PLUS | 82% | 85% | 82% |
| 80 PLUS Bronze | 85% | 88% | 85% |
| 80 PLUS Silver | 87% | 90% | 87% |
| 80 PLUS Gold | 90% | 92% | 89% |
| 80 PLUS Platinum | 92% | 94% | 90% |
| 80 PLUS Titanium | 94% | 96% | 94% |
