Key technologies of the Corsair RM850e PC power supply
- Total power output of 850W
- Fully modular cabling for a clean installation and better airflow
- ATX 3.1 standard supports high component power spikes
- Integrated 12V-2x6 connector powers modern graphics cards without adaptors
- Cybenetics Gold certification confirms high efficiency and low noise
- Zero RPM mode fan only activates under higher loads
- Internal components use capacitors with a 105°C temperature rating
Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the format is its power output. This indicates the maximum number of Watts the power supply can continuously deliver to the components in your computer. It is a good idea to use a web-based calculator to work out the optimal power output based on your chosen components.
Graphics card support
The power supply meets the ATX 3.1 and PCIe 5.1 standard specifications. These standards define the power supply's ability to handle the high, short-term power spikes generated by modern graphics cards. For direct power to modern graphics cards, the cabling includes a native 12V-2x6 connector. This solution eliminates the need for adaptors, which can be a source of problems and overheating. A direct, single-cable connection simplifies installation, improves the look of the case interior, and supports reliable power delivery to the graphics card.
Efficiency and quiet operation
Dual 80 PLUS Gold and Cybenetics Gold certifications confirm high energy conversion efficiency. A 120mm fan with a rifle bearing is responsible for heat dissipation, and features an optimised blade shape for quiet operation. With the Zero RPM function, the fan remains completely switched off at low to medium loads. The fan only activates when power consumption is higher, so the power supply operates completely silently during normal work or less demanding tasks.
Fully modular cabling
The fully modular design means you only connect the cables your build actually needs. The other cables can be safely stored away. The result is a clean and tidy computer interior, where excess cabling doesn't obstruct optimal airflow and component cooling. The flat cables also make routing them easier.
Internal architecture of the power supply
The core of the power supply is a resonant LLC topology with DC-to-DC converters, which ensures precise voltage regulation across all rails. The use of industrial-grade Japanese capacitors rated up to 105°C contributes to long-term stability and reliability. The power supply also supports the Modern Standby function for quickly waking the system from sleep mode. Advanced protection circuits protect the connected hardware against common risks such as overvoltage, undervoltage, overcurrent, or short circuits.

80 Plus certification on the European market
The 80 Plus certification was created to objectively evaluate the efficiency of computer power supplies. This gives users a simple and clear way to compare different models. On the European market (where a 230V voltage is used), there are six levels of 80 Plus certification, each with set requirements for computer power supplies. Higher energy efficiency primarily means lower energy consumption.
