Corsair RM850x ATX 3.1
The Corsair RM850x ATX 3.1 computer power supply, with its 850W output, powers modern PC builds. It meets the ATX 3.1 standard and its 80 PLUS Gold certification confirms 90% efficiency, which reduces both energy consumption and heat production. The fully modular design simplifies cable installation and improves airflow within the PC case. A 140mm fan with Zero RPM mode, which stops completely under low loads, ensures quiet operation. A comprehensive set of five protection types safeguards connected components from damage. The PSU includes a native 12VHPWR connector for graphics cards.

Choosing a power supply
When choosing a suitable PC power supply, the key parameter besides the form factor is its power output. This indicates the maximum number of watts the power supply can continuously deliver to the computer's components. It is a good idea to use a web calculator to determine the optimal power output based on your chosen components.
Quiet operation and Zero RPM mode
A 140mm fan with a fluid dynamic bearing, which reduces friction and operational noise, cools the internal components. The power supply operates with an intelligent Zero RPM mode. This mode keeps the fan completely off under low loads, achieving silent operation during office work or web browsing. The fan only activates when consumption is higher.
Efficiency and the ATX 3.1 standard
The efficiency of electrical energy conversion is confirmed by 80 PLUS Gold and Cybenetics Gold certifications, which define efficiency of up to 90% under typical load. Higher efficiency reduces the amount of waste heat the power supply produces. As a result, internal components operate at lower temperatures, which affects their lifespan and reduces the cooling demands on the PC case. The power supply's design complies with the ATX 3.1 standard. This specification is crucial for the stability of systems equipped with high-consumption graphics cards. Compliance with the PCIe 5.1 standard means it's ready for future hardware generations and their power requirements.
Modern connectivity and installation
The fully modular design simplifies cable installation, as you can connect only the cables you actually need. Included is a 16-pin 12V-2x6 connector, which is used to directly power NVIDIA GeForce RTX 40 series and future generation graphics cards. This connector delivers high power through a single cable. Native support eliminates the need for unreliable and bulky adapters, which simplifies connection and contributes to a cleaner cable arrangement inside the case.

80 Plus certification on the European market
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.
