Product information

Description

The CHIEFTEC CTG-550C Power Supply Unit 550 W ATX Semi-Modular Black is a reliable and efficient power solution designed for standard PC systems. Delivering 550 watts of total power, this ATX power supply features an 80 PLUS certification and active Power Factor Correction to ensure stable energy delivery while minimizing waste. Its semi-modular cabling system helps maintain a clean computer interior by allowing users to connect only the necessary cables, improving overall airflow within the chassis.

Advantages

This power supply combines dependable performance with a practical semi-modular design that simplifies cable management during PC assembly. It operates efficiently under standard 230 V electrical inputs and includes a quiet 12 cm active cooling fan that maintains optimal operating temperatures. Built-in compliance standards such as CE, CB, FCC, and RoHS ensure safety and reliability for everyday computing tasks.

Suitable for

  • Building or upgrading standard desktop PC systems
  • Office and home workstations requiring stable 550 W power delivery
  • Setups benefiting from semi-modular cable management for reduced clutter

When it may not be suitable

This power supply is not intended for high-end enthusiast gaming rigs equipped with multiple high-power graphics cards that require significantly higher wattage. It is also unsuited for industrial server deployments that demand redundant power supplies or non-standard form factors.

Key specifications

  • 550 W total power output
  • ATX form factor and ATX-12V 2.3 standard
  • Semi-modular cabling system
  • 80 PLUS efficiency certification
  • Active PFC with 230 V AC input
  • 12 cm active cooling fan
  • Connectors include 24-pin ATX, 8-pin EPS12V, 8-pin PCI Express, SATA, and Molex

How to use

Mount the power supply unit into the designated lower or upper compartment of a compatible ATX PC case using the included screws. Connect the 24-pin ATX motherboard connector and the 8-pin EPS12V connector to the respective ports on your motherboard. Attach only the required semi-modular cables for your storage drives and graphics cards, keeping unused cables stored safely outside the main airflow path. Plug the power cord into a grounded 230 V wall outlet before turning on the system.

What to consider before purchase

  • Verify that the 550 W capacity meets the total power requirements of your processor and graphics card
  • Check your PC case dimensions to ensure standard ATX power supply compatibility
  • Confirm that the included PCIe and SATA connectors match your hardware components
Usage recommendations: Ensure adequate ventilation around the PC case intake and exhaust areas to allow the 12 cm fan to cool the unit effectively. Avoid overloading the 550 W capacity by calculating the combined peak wattage of all connected system components.

Parallel processing technology support: Parallel processing technology is the simultaneous use of more than one CPU or processor core to execute a program or multiple computational threads. Ideally, parallel processing makes programs run faster because there are more engines (CPUs or Cores) running it. In practice, it is often difficult to divide a program in such a way that separate CPUs or cores can execute different portions without interfering with each other. Most computers have just one CPU, but some models have several, and multi-core processor chips are becoming the norm. There are even computers with thousands of CPUs.
