Corsair CX550

Corsair CX550
The Corsair CX550 computer power supply provides consistent and reliable power for the key components in modern PC builds. It offers a continuous output of 550W, covering the energy demands of mid-range systems. With 80 PLUS Bronze certification, it achieves an operating efficiency of up to 88%, leading to more efficient energy conversion, less residual heat generation, and a direct reduction in electricity costs. The thermally controlled 120mm fan automatically adjusts its speed according to the load, keeping noise levels low during normal operation.
Key technologies of the Corsair CX550 computer power supply
- Total power output covers the energy demands of standard builds
- 80 PLUS Bronze certification confirms high energy conversion efficiency
- Cooling is handled by a fan with automatic thermal speed control
- Compact length makes it easy to install in smaller computer cases
- Fixed cabling includes all the necessary connectors to power components
- Features a convenient mains power switch on the back
Choosing a power supply
When choosing a suitable PC power supply, the key parameter, besides the format, is its wattage. This indicates the maximum number of watts the power supply can continuously deliver to the computer's components. It's a good idea to use an online calculator to determine the optimal wattage based on your chosen components.
80 PLUS Bronze efficiency
The 80 PLUS Bronze certification confirms that the power supply meets strict standards for electrical energy conversion at various load levels. When powering components, it experiences low energy losses, which would otherwise manifest as unwanted heat. The lower operating temperature of this 80 PLUS Bronze power supply directly contributes to a more stable environment inside the case and less stress on other parts, such as the processor or graphics card.
Quiet cooling and compact dimensions
A fan takes care of heat dissipation, with its speed automatically adjusting to the current load. At low loads, the fan spins slowly and operates quietly. Its speed only increases under high performance demands, such as during gaming. With a length of just 125mm, the power supply fits into most modern ATX cases, which simplifies installation and cable management.
Connector options
This non-modular 550W power supply has fixed cabling that includes all the essential connectors for building a standard computer. It provides a main 24-pin ATX connector for the motherboard and one 4+4-pin connector to power the processor. For modern graphics cards, the power supply offers two 6+2-pin PCIe connectors. For storage and other peripherals, there are three SATA connectors and two older Molex-type connectors.
Compact ATX format
The power supply has a standard ATX format but with a depth of only 125mm, which significantly simplifies its installation even in smaller computer cases. This compact size leaves more space for cable routing and promotes better airflow within the build. The design fully complies with the ATX 2.4 specification, confirming its compatibility with current motherboards and components. There is also a convenient mains power switch on the back.

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 comparison between different models. On the European market (where 230V is used), there are six levels of 80 Plus certification with set requirements for computer power supplies. Higher energy efficiency primarily means lower energy consumption.
