Product information

Description

The Chieftec GPB-500S power supply unit delivers a total power output of 500 W, designed specifically for standard desktop PC systems using the PS/2 form factor. Operating on an AC input voltage range of 200 to 240 V, this silver PSU ensures stable and reliable power distribution for everyday computing configurations. It features a 20+4 pin ATX motherboard power connector, non-modular cabling, and three peripheral Molex power connectors for hardware connectivity. Active cooling is handled by a built-in 12 cm fan to maintain appropriate operating temperatures during use.

Advantages

This power supply utilizes state-of-the-art PCB design and reliable components to ensure consistent energy delivery. The active cooling system with a 12 cm fan effectively manages airflow while maintaining operational stability. Its standard PS/2 form factor and 20+4 pin ATX connector offer broad compatibility with common PC cases and motherboards. Additionally, the unit incorporates fixed input operation tailored for standard electrical grids, making it a straightforward and practical choice for standard desktop setups.

Suitable for

  • Standard desktop PC builds and upgrades
  • Office and home workstation configurations
  • General purpose daily computing tasks

This power supply may not be suitable for high-end gaming computers equipped with multiple power-demanding graphics cards, overclocked systems, or enterprise server configurations that require higher wattage output or modular cabling options.

Key specifications

  • Total power: 500 W
  • AC input voltage: 200 - 240 V
  • Form factor: PS/2
  • Motherboard connector: 20+4 pin ATX
  • Peripheral Molex connectors: 3
  • Cooling: Active with 12 cm fan
  • Cabling type: Non-Modular
  • Colour: Silver

Installation requires mounting the unit securely inside a compatible PC case using standard screws and connecting the 20+4 pin ATX cable to the motherboard along with the necessary peripheral connectors. Ensure the system is powered off and disconnected from the electrical outlet before handling any internal components. Route the non-modular cables carefully to avoid obstructing airflow inside the chassis.

What to consider before purchase

  • Verify that the 500 W capacity meets the total power requirements of your system components
  • Check that your PC case supports the PS/2 power supply form factor
  • Confirm the availability of required connectors for your motherboard and peripherals

Always verify your system power consumption against the 500 W capacity before installation and ensure proper ventilation within your PC case for optimal operation.
